摘要 |
A gel has improved thermal stability and is the ultraviolet hydrosilylation reaction product of (A) an organopolysiloxane having an average of at least 0.1 silicon-bonded alkenyl group per molecule and (B) a cross-linker having an average of at least 2 silicon-bonded hydrogen atoms per molecule. (A) and (B) react via hydrosilylation in the presence of (C) a UV-activated hydrosilylation catalyst comprising at least one of platinum, rhodium, ruthenium, palladium, osmium, and iridium, and (D) a thermal stabilizer. The (D) thermal stabilizer is present in an amount of from about 0.01 to about 30 weight percent based on a total weight of (A) and (B) and having transparency to UV light sufficient for the ultraviolet hydrosilylation reaction product to form. |
