ABSTRACT:
An oxime curable silicone sealant composition with good oil resistance can be formulated, using calcium carbonate filler with higher water content than previously known to be useful. The sealant formulation is adjusted to accommodate higher water content by adjusting the ketoximosilane crosslinker level. The correct amount of crosslinker is determined by the hydroxy content present from both the silanol on the base polymer and the water content of the filler.
