Description

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.
