Claims22
A high impact resistant article comprising a breakable substrate bonded to a flexible substrate, wherein the breakable substrate is bonded to the flexible substrate using a pressure sensitive adhesive prepared by combining an acrylic polymer and a silane-functional polymer, wherein the silane-functional polymer has a glass transition temperature of below −20° C.
A pressure sensitive adhesive prepared by combining a pressure sensitive acrylic polymer and a silane-functional polymer wherein the silane-functional polymer has a glass transition temperature of below −20° C. and contains —Si(CxH2x+1)n(OCyH2y+1)3−n, end groups where n is 0, 1 or 2, and x and y are independently integral numbers from 0 to 12.
A pressure sensitive adhesive prepared by combining an acrylic polymer and a silane-functional polymer wherein the silane-functional polymer has a glass transition temperature of below −20° C. and contains —Si(CxH2x+1)n(OCyH2y+1)3−n end groups where n is 0, 1 or 2, and x and y are independently integral numbers from 0 to 12 and wherein the acrylic polymer contains no silyl functional groups.
A pressure sensitive adhesive prepared by combining an acrylic polymer and a silane functional polymer wherein the silane functional polymer is a silane-terminated polyurethane that has a glass transition temperature of below −20° C.
