Abstract
The invention relates to organopolysiloxane compositions which are stable when stored under anhydrous conditions, but when exposed to moisture cure to an elastomer containing (a) a diorganopolysiloxane having terminal condensable groups, (b) a silicon compound having 3 amino groups bonded to silicon via nitrogen and/or oxime groups bonded to silicon via oxygen per molecule and (c) a silicon compound having at least one thiol group selected from mercapto-functional silanes or siloxanes. The presence of the mercapto-functional silanes or siloxanes substantially retards the formation of skin but does not substantially extend the cure time of the organopolysiloxanes compositions. These compositions are useful in, for example, screen printing, where a long skin-over time is desired.
