Asphalt adhesives

A coating composition substantially prevents fraying of glass fiber yarn packages. The composition is composed of an aqueous solution of a resin formed of the hydrolysis product of a copolymer of vinyl aromatic monomer and maleic anhydride, an organo silane glass fiber anchoring agent and an effective amount of a water-soluble pyrrolidone-containing polymer sufficient to form a protective film over the glass fiber.

Thermal insulating articles are disclosed of the type which comprises a laminate of thermal insulation and a flexible jacket material with the jacket and thermal insulation being directly adhesively adhered to each other by means of a hot-melt adhesive. The hot-melt adhesive employed consists essentially of an asphalt, an ethylene-vinyl acetate copolymer and a wax. Also provided is a hot-melt adhesive which consists essentially of an asphalt, an ethylene-vinyl acetate copolymer and a compatible wax, which is especially useful in adhering paper used as package wrap.

Hot-melt adhesive

The insulation batt has a facing with a facing flange, the facing flange having pressure-sensitive adhesive thereon and being folded inwardly to engage the pressure-sensitive adhesive with a release strip on the inside of the facing and dispose the facing flange flush with an edge of the batt. For installation of the batt, the facing flange is unfolded outwardly to expose the pressure-sensitive adhesive.
