  • the present disclosure relates, in general to temporary protection of coated glass substrates, and more specifically to a water-based temporary protective coating for heat treatable glass substrates provided with a functional coating.
  • Glass surfaces remain an enduring area of scientific and technological challenges for applications of glass, and approaches to understand and customize its surface. Interfacial behaviors with glass modifications and functional coatings represent a critical direction for glass’ future.
  • Glass substrates are increasingly being deposited with functional coatings to improve performance and durability. Widely used and popular functional coatings include solar control, conductive, antireflective and/or low emissivity coatings.
  • Other coatings that modify the various physical properties of glass substrates such as optical, thermal or mechanical properties are also common.
  • Such coated glass substrates are usually shipped from manufacture sites to fabricator locations for further processing such as cutting, grinding, bending etc.
  • the known shipping methods are inadequate for transporting glass substrates deposited with functional coatings without causing any damage to these coatings.
  • the functionally coated surface of one coated glass substrate during handling, processing, shipping or storage could possibly damage or scratch the functional coating of an adjacent coated glass substrate.
  • these functional coatings cannot survive temperatures higher than 200 °C or 250 °C without suffering some form of degradation and also cannot be subjected to further processing steps post coating due to the susceptibility of these coatings to such processing steps.
  • these functionally coated glass substrates need to be shaped, sized, cut, ground, edge grinded and / or processed prior to the coating process as, such processing are not possible post the coating process as well as post the heat treatment. This constraint posts significant challenges while trying to achieve a continuous production process.
  • a functionally coated glass substrate may be covered with a layer of IR or UV curable enamel, cured and then heat treated.
  • a curing process does not provide mechanical resistance and water resistance sufficient for allowing the coated glass substrate to be transported, cut, edge-worked, stocked, and/or otherwise processed, before the heat treatment.
