THERMALLY STABLE ORGANOSILOXANE COMPOSITIONS AND METHOD FOR PREPARING SAME

摘要

THERMALLY STABLE ORGANOSILOXANE COMPOSITIONS AND METHOD FOR PREPARING SAME Small amounts, typically from about 0.001 to about 0.05 percent by weight, of certain aliphatic and cycloaliphatic mono-, di- and triamines have been shown to retard the heatinduced discoloration to materials prepared by curing unfilled organosiloxane compositions comprising a specified class of vinyl-substituted polyorganosiloxanes, an organohydrogensiloxane and a platinum-containing hydrosilation catalyst. Preferred amines will also function as platinum catalyst inhibitors, and impart long term storage stability to these curable organosiloxane compositions when packaged in a single container.
