Description

MPM5072671 - foreign filing text MOISTURE-CURABLE RESIN COMPOSITIONS FIELD OF THE INVENTION The invention relates to moisture-curable silylated resin compositions, cured resin compositions, obtained from such moisture-curable silylated resin compositions, coating, sealant or adhesive compositions comprising the moisture-curable silylated resin compositions, cured coatings, sealants or adhesives obtained therefrom, a process for the manufacture of a coating, sealant or adhesive, and coated, sealed or bonded articles comprising a substrate with cured coatings, sealants or adhesives obtained by curing the moisture-curable coating compositions on a substrate. BACKGROUND OF THE INVENTION Moisture-curing compositions based on silane-functional polymers have been used for some time as elastic adhesives, sealants and coatings. Since they are free of isocyanate groups, they constitute a preferred alternative to isocyanate-containing polyurethane compositions from a toxicological point of view. Moisture-curable silylated resins including those obtained from the silylation of polyurethanes derived from polycarbonate diols or polyether polyols and polyisocyanates are known and are valued for the functional properties they confer on coating, sealant and adhesive compositions containing them. However known moisture-curable silylated resins, including those of the aforementioned silylated polycarbonate diol- or polyether polyol-based polyurethane type, may fail to perform acceptably in a given coating, sealant or adhesive composition, either during the application of these products and/or in their post-cured properties, in particular in that they may not show balanced physical properties in respect to elongation, tensile strength and adhesion on damp substrates which is desired in multiple applications, including coating, adhesive and sealants (CAS). Specifically, coatings based of silylated polycarbonate urethane polymer composition resulted in excellent adhesion to damp and alkaline concrete, which is highly desired in construction of new structures or repair jobs to reduce time instead of conventional practice to wait for substrate to dry or come near neutral pH before applying coatings. However, silylated- polycarbonate urethane-based coatings lacked desired elongation property required for such applications. Polymeric resins or binders are the key ingredient used in CAS formulations to achieve target mechanical and performance properties. However, each resin has its own advantages and disadvantages. Even when a combination is used, it is difficult to get the “best of both worlds”. JP2015113375A discloses an aqueous adhesive comprising an acid-modified polyolefin resin (A) and a silanol group-containing polyurethane resin (B). US20200109230A1 describes silylated polycarbonate urethane resins. WO2011123351A1 and WO2008060506A2 describe silylated polyether urethane resins. However, these patents do not disclose how to MPM5072671 - foreign filing text improve mechanical properties, specifically elongation and to improve wet adhesion (damped concrete). SUMMARY OF THE INVENTION In accordance with one aspect of the invention, there is provided a moisture-curable resin composition comprising: (A) one or more silylated polycarbonate urethane resins, and (B) one or more silylated polyether urethane resins, resins (A) and (B) being different from each other. The composition comprising a silylated polycarbonate urethane resin (A) and a silylated polyether urethane resin (B) resulted in surprisingly improved balance of mechanical properties such as elongation, tensile strength and at the same time provide improved adhesion in particular on damp substrates such as wet and alkaline concrete which is desired in multiple applications, including coating, adhesive and sealants (CAS). DETAILED DESCRIPTION OF THE INVENTION In the moisture-curable resin composition according to the invention resins (A), the silylated polycarbonate urethane resins, are obtained suitably by reacting one or more polycarbonate polyols (C) with one or more polyisocyanates (E) and subsequent reaction with one or more functional silanes (F).

In such case the group O groups form a urethane group of the formula MPM5072671 - foreign filing text or . In another, more preferred synthetic approach, an isocyanate-terminated polyurethane is reacted with an amino (-NH2)-functional silane (R⁵ = H) or preferably with a secondary amino functional (-NH(R⁵))-functional silane (R⁵ = monovalent organic group).

A particular preferred silylated polycarbonate urethane resin (A) is obtained by the reaction of a polycarbonate diol with an excess of isophorone diisocyanate (IPDI) terminal groups and subsequent capping reaction of the resulting intermediate with a small excess of N-(n-butyl)-3-aminopropyltrimethoxysilane: MPM5072671 - foreign filing text . synthesis of such resins (A) in greater details.

The terminal silyl units -A-R⁶-SiR⁷3-e(OR⁸)e or (OR⁸)eR⁷3-eSi-R⁶-A- are basically the same as for the silylated polycarbonate urethane resins (A) as described herein. Particular silylated polyether urethane resins (B) are selected from the group of formulas: a are as As a hydroxy-terminated polyurethane prepolymer with an isocyanate-functional silane (F) leads to the resin (B) of the former formula and endcapping of an isocyanate terminated polyurethane prepolymer with an amino functional silane (F) leads to the resin (B) of the latter formula. Similar as described for the silylated polycarbonate urethane resins (A) above, in an embodiment depending on the molar ratios of the educts (polyether polyols (D), polyisocyanates (E) and functional silanes (F)), the synthesis of the silylated polyether urethane resins (B) may lead to a mixture comprising for example one or more of the following species (B1), (B2), (B3) (here again exemplified with using N-(n-butyl)-3- aminopropyltrimethoxysilane: as component (F)):

The polycarbonate polyols (C) suitably have the formula: d from hydroxy or a two to eight functional organic moiety, R² is as defined above, c is more than about 5, preferably about 5 to about 1000, more preferably 5 to 100, still more preferably 10 to 50, still more preferably 10 to 20, with the provisos that d is 1 in case R³ is hydroxy and d is 2 to 8 in case R³ is a two to eight functional organic moiety, and preferably R³ is hydroxy and d is 1, or d is 2. Particularly preferred are the polycarbonate diols described in US 10,538,612B2 and include polycarbonate diols which can be obtained by reacting at least one carbonylating agent with diol of which at least 80 mole percent, preferably at least 90 mole, and more preferably at least 95 mole percent and still more preferably 100 mole percent, is at least one of a mixture of at least two different acyclic straight chain aliphatic diols, each such diol possessing up to 12 carbon atoms, preferably 2 to 12 carbon atoms, and more preferably from 2 to 10 carbon atoms; at least one acyclic branched chain aliphatic diol possessing up to 12 carbon atoms, MPM5072671 - foreign filing text preferably 3 to 12 carbon atoms and more preferably from 3 to 10 carbon atoms; and, a mixture of at least one straight chain aliphatic diol possessing up to 12 carbon atoms, preferably 2 to 12 carbon atoms and more preferably from 2 to 10 carbon atoms, and at least one acyclic branched chain aliphatic diol possessing up to 12 carbon atoms, preferably 3 to 12 carbon atoms and more preferably from 3 to 10 carbon atoms. Suitable carbonylating agents for reaction with the aforementioned polyol(s) to produce polycarbonate diol(s) include, but are not limited to, phosgene, triphosgene, [1,3,5] trioxane-2,4,6-trione, aliphatic and aromatic carbonates (carbonate esters) such as dialkyl carbonates, diarylcarbonates, alkylene carbonates, alkylaryl carbonates, and mixtures thereof. For example, the carbonate compound can be dimethyl carbonate, diethyl carbonate, di-n-butyl carbonate, diisobutyl carbonate, diphenyl carbonate, methylphenyl carbonate, ethylene carbonate, propylene carbonate, and mixtures thereof. Of these carbonylating agents, phosgene, dialkyl carbonates such as dimethyl carbonate and diethyl carbonate, and alkylene carbonates such as ethylene carbonate and propylene carbonate are generally preferred with phosgene being more preferred. In one embodiment of a polycarbonate diol at least two different acyclic straight chain aliphatic diols each possessing from 2 to 12 carbon atoms, and preferably from 2 to 10 carbon atoms, are reacted with the selected carbonylating agent(s) to provide a mixture of copolycarbonate diols. Among the suitable acyclic straight chain aliphatic diols that can be used for the preparation of a mixture of copolycarbonate diols are ethylene glycol, 1,3- propanediol, 1,4-butanediol, 1,5-pentanediol, 1,6-hexanediol, 1,7-heptanediol, 1,8-octanediol, 1,9-nonanediol, 1,10-decanediol, and the like. The proportions of acyclic straight chain aliphatic diols to each other can vary widely, e.g., from 20 to 80 mole percent, and preferably from 40 to 60 mole percent, of a first acyclic straight chain aliphatic diol with the balance being made up of second, third, etc., acyclic straight chain aliphatic diol(s). With further regard to this embodiment of polycarbonate diol it is especially advantageous to employ a mixture of two or more different acyclic straight chain aliphatic diols in which at least one such diol possesses an even number of carbon atoms and at least one other such diol possess an odd number of carbon atoms. The diol(s) possessing an even number of carbon atoms can represent from 20 to 80 mole percent, and preferably, from 40 to 60 mole percent, of the diol mixture with the diol(s) possessing an odd number of carbon atoms making up the remainder of the diol mixture. In accordance with this particular embodiment, some suitable diol mixtures include the following: Acyclic Straight Chain Aliphatic Diol(s) of Even Carbon Acyclic Straight Chain Aliphatic Diol Number, mole percent Diol(s) of Odd Carbon Number, Mixture mole percent A ethylene glycol, 50 1,3-propanediol, 50 MPM5072671 - foreign filing text B ethylene glycol, 60 1,3-propanediol, 40 C ethylene glycol, 60 1,5-pentanediol, 40 D 1,4-butanediol, 40 1,3-propanediol, 60 E ethylene glycol, 30 1,5-pentanediol, 20 1,4-butanediol, 20 F 1,4-butanediol, 60 1,5-pentanediol, 40 G ethylene glycol, 50 1,7-heptanediol, 50 H 1,6-hexanediol, 50 1,5-pentanediol, 50 I 1,4-butanediol, 40 1,5-pentanediol, 30 1,7-heptanediol, 30 J 1,4-butanediol, 60 1,7-heptanediol, 40 K ethylene glycol, 35 1,5-heptanediol, 15 1,4-butanediol, 40 1,7-heptanediol, 15 In an embodiment, use of such mixtures of acyclic straight chain aliphatic diols in the preparation of polycarbonate diols has been found to reduce the crystallinity of the product copolycarbonate diols even further compared with the use of mixtures of acyclic straight chain copolycarbonate diols in which all, or nearly all, of the constituent diols have chain lengths having an even number of carbon atoms or conversely, an odd number of carbon atoms. In another embodiment of polycarbonate diol, at least one acyclic branched aliphatic diol possessing up to 12 carbon atoms, and preferably from 3 to 10 carbon atoms, is reacted with carbonylating agent(s) to provide the polycarbonate diol. Suitable acyclic branched diols include, but are not limited to, 2-methyl-1,3-propanediol, 2-methy-1,4-butanediol, 2,3-dimethyl- 1,4-butanediol, 2-methyl-1,5-pentanediol,3-methyl-1,5-pentanediol, 2,2,4-trimethyl-1,6- hexanediol, 3,3,5-trimethyl-1,6-hexanediol, 2,3,5-trimethyl-1,6-pentanediol, 2-methyl-3-ethyl- 1,5-pentanediol, 2-ethyl-3-propyl-1,5-pentanediol, 2,4-dimethyl-3-ethyl-1,5-pentanediol, 2- ethyl-4-methyl-3-propyl-1,5-pentanediol, 2,3-diethyl-4-methyl-1,5-pentanediol, 3-ethyl-2,2,4- trimethyl-1,5-pentanediol, 2,2-dimethyl-4-ethyl-3-propyl-1,5-pentanediol, 2-methyl-2-propyl- 1,5-pentanediol, 2,4-dimethyl-3-ethyl-2-propyl-1,5-pentanediol, 2-butyl-2-ethyl-1,5- pentanediol, and 3-butyl-2-propyl-1,5-pentanediol and combinations thereof. Of these acyclic branched aliphatic diols, 2-methyl-1,3-propanediol, 2-methyl-1,4-butanediol, 2,3-dimethyl-1,4-butanediol and 2-methyl-1,5-pentanediol and mixtures thereof are preferred for use in the preparation of polycarbonate diols. Where mixtures of acyclic branched chain aliphatic diols are used, it can be advantageous to employ at least one such diol possessing an even number of carbon atoms and at least one such diol possessing an odd number of carbon atoms. MPM5072671 - foreign filing text In yet another embodiment, polycarbonate diol and mixtures of such diols are obtained from the reaction of the selected carbonylating agent(s) with mixtures containing at least one acyclic straight chain diol and at least one acyclic branched chain aliphatic diol of the foregoing types. The proportions of acyclic straight chain aliphatic diol(s) and acyclic branched chain diol(s) can vary widely in these diol mixtures, e.g., from 20 to 80 mole percent, and preferably from 40 to 60 weight percent, of the former with the latter making up the balance of the diol mixtures. Here also it can be advantageous to employ diol mixtures in the preparation of polycarbonate diols in which at least one constituent diol, e.g., acyclic straight chain aliphatic diol, possesses an even number of carbon atoms and at least one other constituent diol, e.g., acyclic branched chain aliphatic diol, possesses an odd number of carbon atoms or vice versa. Some suitable mixtures of acyclic straight chain aliphatic diol(s) and acyclic branched chain aliphatic diol(s) for preparation of polycarbonate diols include the following: Acyclic Branched Chain Diol Acyclic Straight Chain Aliphatic Aliphatic Diol(s), mole percent Mixture Diol(s), mole percent L ethylene glycol, 50 2-methyl-1,4-butanediol, 50 M ethylene glycol, 50 2-methyl-1,4-butanediol, 50 N 1,3-propanediol, 50 2-methyl-1,3-propanediol, 50 O 1,4-butanediol, 65 2,3-dimethyl-1,4-butanediol, 35 P ethylene glycol, 30 2-methyl-1,3-propanediol, 45 1,3-propanediol 25 Q 1,4-butanediol, 60 2-methyl-1,5-pentanediol, 40 R 1,6-hexanediol, 60 3-methyl-1,5-pentanediol, 40 S ethylene glycol, 30 2-methyl-1,5-pentanediol, 30 1,4-butanediol, 20 2,4-dimethyl-3-ethyl-1,5- pentanediol, 20 T 1,4-butanediol, 50 2-methyl-1,4-butanediol, 50 1,6-hexanediol, 25 The reaction of diol(s) with carbonylating agent(s) can be carried out in accordance with known and conventional procedures to produce polycarbonate diol(s). As the reaction proceeds, by- product(s) of the reaction, e.g., HCl in the case of phosgene as carbonylating agent and alkanol(s) in the case of dialkyl carbonates as carbonylating agents, are advantageously removed from the reaction zone on a continuous basis. The amounts of diol(s) and carbonylating agent(s) may vary provided copolycarbonate diol(s) are obtained. Thus, for example, the mole ratio of total diol(s) to total carbonylating agent(s) can vary from 2.0:1.0 to MPM5072671 - foreign filing text 1.01:1.0 and preferably from 1.3:1.0 to 1.1:1.0. In an embodiment, it is generally preferred to employ a molar excess of diol(s) to carbonylating agent(s). In some cases, it may be desirable to employ at least one catalyst for the reaction of carbonylating agent and diol to produce polycarbonate diol(s), e.g., a transesterification catalyst. Suitable transesterification catalysts include, but are not limited to, titanium compounds such as titanium tetrachloride and tetraalkoxytitaniums such as tetra-n-butoxy- titanium and tetraisopropoxytitanium; metallic tin and tin compounds such as tin(II)hydroxide, tin(II)chloride, dibutyltin laurate, dibutyltin oxide, and butyltin tris(ethylhexanoate). Of the aforementioned transesterification catalysts, it is preferred to employ one or more of tetra-n- butoxytitanium, tetraisopropoxytitanium, dibutyltin laurate, dibutyltin oxide and butyltin tris(ethylhexanoate). The catalyst will be present is the transesterification reaction medium in at least a transesterification catalyzing-effective amount, for example, in an amount of from 1 to 5,000 ppm, and preferably from 10 to 1,000 ppm, based on the weight of the diol reactant(s). The reaction conditions employed for producing polycarbonate diol can vary widely, again, provided polycarbonate is obtained. For example, specific reaction conditions include heating the reaction mixture at a temperature of from 110 to 200^o C under ambient atmospheric pressure for 1 to 24 hours, then at a temperature of from 110 to 260^o C, preferably 140 to 240^o C under reduced pressure for from 1 to 20 hours, and then under reduced pressure gradually taken down to 20 mmHg or less at 140 to 240^o C for 0.1 to 20 hours. The reactor is preferably provided with a means, e.g., a distillation column, to remove by-product(s) of the reaction as it/they are produced. Polycarbonate diol can advantageously possess a number average molecular weight as measured in accordance with ASTM D5296-11, Standard Test method for Molecular Weight Averages and Molecular Weight Distribution of Polystyrene by High Performance Size- Exclusion Chromatography of from 400 to 5,000, preferably from 500 to 4,000 and more preferably from 1500 to 3000, and a hydroxyl value (KOH mg/g) as measured in accordance with ASTM E222-10, Standard Test method for Hydroxyl Groups Using acetic Anhydride Acetylation, of from 25 to 250 and preferably from 50 to 125. The polyether polyols (D) suitably used to prepare the silylated polyether urethane resins (B) comprise two or more units of the formula: selected from a divalent aliphatic or alicyclic hydrocarbyl group with 2 to 6 carbon atoms, preferably independently selected from ethylene, propylene, and butylene, More specifically the polyether polyols (D) suitably have the formula: MPM5072671 - foreign filing text R_O 1 _{O R}1 R _{O H} b from hydrogen or a two to eight functional organic group, R¹ as and a is more than about 5, preferably about 5 to about 1000, with the provisos that b is 1 in case R is hydrogen and b is 2 to 8 in case R is a two to eight functional organic moiety, and preferably R is hydrogen and b is 1 or b is 2. Suitable polyether polyols (D) are described e.g. in US 7,732,554 B2, the relevant disclosure of which is herein included by reference to such patent. Such polyether polyols include for example hydroxyl-terminated polyether polyols such as at room temperature liquid polyether polyols possessing at least two terminal hydroxyl groups. Specific suitable polyether polyols include the polyether diols, in particular, the poly(oxyethylene) diols, the poly(oxypropylene) diols and the poly(oxyethylene-oxypropylene) diols, polyoxyalkylene triols, polytetramethylene glycols and the like. In one embodiment of the present invention, the polyols used in the production of the silylated polyurethane resins (B) are poly(oxyethylene) diols with number average molecular weights from about 500 to about 25,000 grams per mole (g/mol). In another embodiment of the present invention, the polyols used in the production of the silylated polyurethane resins are poly(oxypropylene) diols with number average molecular weights from about 1,000 to about 20,000 grams per mole. Mixtures of polyols of various structures, molecular weights and/or functionalities can also be used. The polyether polyols can have specifically functionality up to about 8 hydroxyl groups per polymer chain and more specifically have a functionality of from about 2 to 4 hydroxyl groups per polymer chain and most specifically, a functionality of 2 hydroxyl groups per polymer chain (i.e., diols). Especially suitable are the polyether polyols prepared in the presence of double- metal cyanide (DMC) catalysts, an alkaline metal hydroxide catalyst, or an alkaline metal alkoxide catalyst; see, for example, U.S. Pat.

Polyether polyols produced in the presence of double-metal cyanide catalysts tend to have high molecular weights and low levels of unsaturation, properties of which, it is believed, are responsible for the improved performance.
