Abstract: Hot-tackifying tape, the adhesive layer of which is virtually nontacky at 20.degree. C. but forms strong bonds to inorganic substrates at elevated temperatures, which bonds have surprisingly good resistance to prolonged exposure to high humidity and high temperatures. The adhesive layer is an acrylic-silane interpolymer of primarily acrylic ester monomer interacted with an organosilane, which interpolymer has a T.sub.g of -10.degree. to 80.degree. C.

Abstract: A two-part pourable composition capable of forming a dielectric, thermally stable, hydrolytically stable, moisture insensitive polyurethane gel comprising in a first part an aliphatic or cycloaliphatic isocyanate and an aliphatic/naphthenic hydrocarbon oil, and in a second part a polyalkadiene polyol, a dialkyl organotin catalyst, and the aliphatic/naphthenic oil. The gel is ideally suitable as a filler for communication cable splices since it is substantially inert toward molded polycarbonate connectors conventionally used in such splices.

Abstract: An electrically insulating composition especially adapted for insulating terminations or splices of oil-impregnated cables comprises an electrically insulating organic liquid and a reactive thickening agent. Initially the composition is a liquid having a low viscosity permitting it to be conveniently poured into place in a termination housing or splice casing. After reaction of the thickening agent, the composition thickens to prevent undesired drainage of the composition.
