Claims9
A plasticized sulfur composition comprising at least 50% by weight sulfur, a sulfur plasticizer, a finely divided particulate mineral suspending agent and an organosilane stabilizing agent having the formula R--Si(OR').sub.3 wherein R is an organic radical having at least one functional group selected from the group consisting of amino, epoxy, vinyl, methacryloxy and mercapto groups, and wherein R' is a low molecular weight alkyl group.
A plasticized sulfur coating composition comprising about 80% by weight sulfur, about 2% by weight of an aromatic polysulfide formed by reacting 1 mol of phenol with at least 2 mols of sulfur, 0.5% by weight of a linear aliphatic polysulfide having the recurring unit
- --S.sub.x CH.sub.2 CH.sub.2 OCH.sub.2 OCH.sub.2 CH.sub.2 S.sub.x --
- about 18% by weight mica, and about 0.2% by weight gamma-glycidoxypropyltrimethoxysilane.
