Definitions
- the present invention relates to a reaction resin which contains at least ethyl methacrylate, a prepolymer with an acid number in the range from 1 to 12 mg (KOH)/g. and optionally contains either an initiator or an accelerator.
- the invention relates to a 2K system which comprises the reaction resin according to the invention and a hardener component, and the use of the 2K system as a road marking, road repair compound, intumescent coating, floor coating, casting resin, building protection, membrane, sealing, coating agent and/or laminating agent.
- Reactive resins and 2K systems containing them are known as such. Reducing the volatile components of a reactive resin and thus the exposure of processors and the odor nuisance when using it has been the goal of development for a long time. Such reaction resins are described in various prior art documents.
- EP 2 739677 B1 relates to an odor-free (meth)acrylic reaction resin which contains high-boiling reactive (meth)acrylic monomers from the group of polar cyclically substituted esters. These are used as a replacement for methyl (meth)acrylate (MMA).
- MMA methyl (meth)acrylate
- WO 2016/026757 A1 discloses a dirt-repellent reaction resin seal for marking or coating floor surfaces or roadways, such as roads, based on cold plastic. This seal results in reduced dirt adhesion, particularly in hot and/or dry, dusty environments. This means that the marking remains more visible than conventional markings, even in dry, hot regions.
- the disadvantage of the method described is the additional effort required to apply two marking layers.
- WO 2011/006767 A1 discloses formulations for marking roadways, such as roads, which can be driven on again after application after a shortened waiting time.
- the examples describe the use of polymers with acid functions.
- the disadvantage of the disclosed reactive resins is the high proportion of crosslinkers, which means that the road markings have little flexibility and tend to become brittle and chip, particularly when applied in thicker layers.
- WO 2013/185993 A1 discloses formulations (reactive resins) for marking or coating floor surfaces or roadways, such as roads.
- the formulations have reduced health hazards and good mechanical properties.
- fast-curing reaction resins with a low content of accelerating amines should be made available.
- the document relates in particular to reaction resins that contain asymmetric aromatic tertiary amines as an accelerator component.
- the disadvantage of the disclosed reactive resins is that they only address the health risks caused by the accelerating amine component and their efficiency in the resins, while other usage properties remain unchanged, i.e. H. especially unchanged dirt absorption. Measures to reduce the health risks for processors due to exposure to volatile components such as methyl (meth)acrylate or the use of peroxides containing phthalate are not described.
- CN 105 753 367 A describes a resin-containing composition for bridge repairs.
- the resin contains two different types of monomers, prepolymers and an initiator.

- reaction resins described in the prior art already have good properties with regard to their smell. However, they often have disadvantages in terms of their processing and/or their tendency to get dirty. In addition, they often do not provide a solution for reducing the emission of monomers, but simply mask their smell by adding fragrances.
- reaction resins and 2K systems that do not have, or only to a reduced extent, the disadvantages of the reaction resins and 2K systems described in the prior art.
- the alternative reaction resins and 2K systems should have reduced emissions of organic components during processing.

Therefore they are less flammable.
- the reaction resins also have increased flexibility and reduced shrinkage, which improves their impact strength and reduces cracking in coatings made from them.
