Abstract (en)
[origin: WO2019043182A1] The invention relates to a composition for refining a substrate, in particular glass, containing a binding matrix formed from silazane, preferably cyclo-silazane, and a cross linking agent, the crosslinking agent preferably being an alkoxy silane or an alkylamine silane. The composition also contains hard particles which have a Vickers hardness of more than 1200HV1. The matrix inclusive of hard particles penetrates the surface of the substrate, whereby the hardness and mechanical load-bearing capability of the surface are improved. The refining is particularly well suited for the protection of mobile telephone displays, and displays of other mobile devices and electronic devices.
