Cold bond adhesive

摘要

An adhesive composition which requires no applied heat to effect curing and which produces a strong bond between a polymeric capping membrane suitably employed in roofing or siding and a roofing or siding base or substrate which composition essentially comprises a homogeneous 60 to 75% solids mixture of(a) between about 0.5 and about 15 wt. % of a thermosetting styrene/isoprene/styrene block polymer containing up to 90% styrene;(b) between about 13 and about 30 wt. % aromatic hydrocarbon solvent containing from about 5 to about 20 wt. % aliphatic hydrocarbon;(c) between about 20 and about 70 wt. % non-blown asphalt optionally containing a minor amount of blown asphalt;(d) between about 1 and about 10 wt. % metal silicate and(e) between about 0.1 and about 5 wt. % of a C6 to C16 alkoxyalkyl amine substituted ester of a C2 to C12 carboxylic acid as a surfactant.The invention also relates to the method of preparing and using the above adhesive composition.
