Accelerated inhibited platinum-catalyzed organosilicon compositions.

摘要

Organopolysiloxane compositions are disclosed which are reactive by way of a platinum-catalyzed hydrosilylation reaction which is inhibited for hours at room temperature but which proceeds readily at temperatures as low as 180 DEG F. This is accomplished by mixing a reaction-inhibitor component and a reaction-accelerator component with the reactive composition. Paper-coating compositions having a long room temperature pot life and a short cure time at 180 DEG F are disclosed.
