Silicone-coated architectural glass

摘要

An extremely durable, stable and fast-curing elastomeric composition suitable for coating all types of architectural glass is disclosed. The coating comprises the following components in the following approximate weight percentages: (a) 75-90 wt % of a crosslinked polyvinylsiloxane/liquid silicone rubber component which, prior to crosslinking, contains the following components: dimethylvinyl-terminated dimethylsiloxane; dimethylvinylated, trimethylated silica; dimethylvinyl-terminated dimethyl, methylvinyl siloxane; dimethyl, methylhydrogen siloxane; and a platinum metal complex as a catalyst; (b) 1-10 wt% of a mixture of methylhydrogen siloxane and methylhydrogen cyclosiloxanes as a coupling agent/adhesion promoter; (c) 1-10 wt% vinyl-terminated dimethylsiloxane as a flowability- enhancing agent; (d) 1-10 wt% hydrogen-terminated dimethylsiloxane as a flowability-enhancing agent; and (e) 0 - 6 wt % pigment. A composite article comprising a glass substrate or metallic-coated glass substrate coated with the coating is also disclosed.
