Abstract
Siloxane-based pipe coatings include a hot melt processable siloxane-based elastomeric polymer, and may optionally contain fillers and additives. The siloxane-based elastomeric polymer is a urea-containing segmented copolymer or an oxamide-containing segmented copolymer. The coatings are substantially free of tackifying resins and are non-tacky and non-adhesive until heated to a temperature of at least 50 C.
