High Performance Reactive Pressure Sensitive Adhesive Composition

Abstract:

Provided herein is a high performance reactive pressure sensitive adhesive (HPR-PSA) formulation which can be compounded and coated on facestock at ambient temperatures. Upon curing by exposing to a high temperature, the HPR-PSA becomes a structural adhesive with superior mechanical performance. This HPR-PSA formulation comprises the unique mixture of the SIS and SB rubber, hydrocarbon and rosin resins tackifiers, and a phenolic derivative curing agent.
