Resin-modified contact adhesive for use on polyethylene surfaces, e.g. in consumer electronics and cars, comprises acrylate copolymer with a very low glass transition point and special compatible tackifying resin

摘要

A resin-modified pressure-sensitive adhesive (I) comprising a mixture of (A) an acrylate polymer and (B) 45-55 wt% highly-compatible tackifying resin, in which (I) shows a tan-delta max value of at least 1.7 at the glass transition point (Tg) and a Tg of 0-8[deg]C as measured by DMA temperature sweep (10 rad/s; -50 to 120[deg]C) and the copolymer (A) shows a Tg of -35 to -42[deg]C.
