    摘要: A method for the coating of glass surfaces in order to prevent the scattering of glass particles upon bursting, with a transparent, duroplastic protective coat by depositing a paste of hydroxy group-containing 1,2-epoxy compounds with at least one 1,2-epoxide group in the molecule and a lower melting point of more than 40.degree. C. and hardening agents, and hardening the overlay at higher temperatures; which comprises first treating the clean glass surface with an aqueous or alcoholic silane skim coat, drying said surface if necessary and thereafter warming said surface to a temperature up to 120.degree. C., coating the glass surface with said paste of hydroxy group containing 1,2-epoxy compounds and hardening said paste with further addition of heat, wherein said hardening agents are polyisocyanates blocked with cyclic amidines of the general formula ##STR1## wherein the R's are the same or different substituents selected from the group consisting of hydrogen, alkyl-, cycloalkyl-, arylalkyl- and aryl, wherein the hardening agent is added in an amount of 2-15% by weight, calculated with respect to the amount of 1,2-epoxide compounds.
