Method for making organically-modified, radiation-curable siloxane resins

摘要

There is disclosed herein a radiation-curable, organically-modified siloxane resin composition which is prepared from (A) at least one multifunctional acrylate and (B) the reaction product formed from (a) an alkoxy-functional organometallic compound, (b) an alkoxysilane and (c) water. The alkoxysilane (b) includes at least one functional group that renders the alkoxysilane copolymerizable with the multifunctional acrylate (A). In the preferred embodiment, the alkoxy-functional organometallic compound (a) and the alkoxysilane (b) undergo cohydrolysis and cocondensation in the presence of a siloxane polymerization catalyst (d).
