Stable, Low Temperature Cure Semi-Structural Pressure Sensitive Adhesive (Stable, Low Cure-Temperature)

摘要

(1) one or more polymers resulting from the polymerization of one or more free radically polymerizable monomers; (2) at least one cationically polymerizable monomer; (3) a photoactivatable catalyst system for at least one organometallic complex salt or at least one onium salt containing cationic polymerizable monomer; (4) conversion of the cationically polymerizable monomer of the curable pressure sensitive adhesive for at least 10 days at about 20C, 50% RH, optionally containing monovalent or polyhydric alcohols, while maintaining the elimination of actinic radiation capable of activating the catalyst system A curable pressure-sensitive adhesive having a long storage stability and a process for producing the same are provided.
