WATER VAPOR-PERMEABLE, PRESSURE-SENSITIVE ADHESIVES
摘要:
Water-permeable, pressure-sensitive adhesives and adhesive constructions are characterized by a MVTR of at least 1,900 g/m2/day and low adhesive edge lift, even after 25 kGy gamma irradiation. The copolymers are formed from a plurality of acrylic monomers, preferably butyl acrylate, 2-ethylhexyl acrylate, hydroxyethyl acrylate, and optionally N-vinyl pyrrolidone.
