Crosslinkable pressure-sensitive adhesives containing a liquid copolymeric organopolysiloxane

摘要

The invention relates to a method of contacting two components to form a pressure-sensitive adhesive (PSA) construction, wherein the first component comprises a conventional PSA and a liquid copolymeric organopolysiloxane and the second component comprises the PSA and a cure agent for the liquid copolymeric organopolysiloxane. The method provides improved adhesion over the unmodified PSA as measured by bond strength and/or the percentage of cohesive failure of the construction, which bond strength generally increases with the passage of time.
