Patent ID: 7211637

Claim:
A single component addition curable polysiloxane system comprising: (a) a siloxane reagent having at least one unsaturated organic functional group for a crosslinking reaction; (b) a crosslinking reagent comprising a silicon hydride group for said crosslinking reaction, wherein said silicon hydride of said crosslinking reagent is sterically hindered, wherein said crosslinking reagent is represented by a nominal formula selected from the group consisting of: wherein R 1 and R 2 each comprise a non-reactive alkyl group having 4 or more carbon atoms and each respective R 3 , R 4 , and R 5 is each independently selected from the group consisting of: a non-reactive organic group and hydrogen; and (c) a catalyst, wherein the single component addition curable polysiloxane system has flowability at ambient conditions prior to said crosslinking reaction.
