Abstract:
A process for making UV curable pressure sensitive adhesive compositions by derivatizing an acrylic polymer with a derivatizing agent prepared from a hydroxy-functional acrylate monomer and a diisocyanate. The derivatizing agent typically has a ratio of hydroxy-functional acrylate monomer to diisocyanate greater than about 1:1. Also disclosed are UV curable pressure sensitive adhesives made with the derivatizing agent and methods for adhering substrates with pressure sensitive adhesive compositions.
Abstract:
The invention relates to a process for making e-Beam curable pressure sensitive adhesive compositions by derivatizing an acrylic polymer having one or more hydroxy groups or one or more acid groups with a derivatizing agent prepared from a hydroxy-functional acrylate monomer and a diisocyanate. The pressure sensitive adhesive can be effectively cured without a photoinitiator or reactive diluent. Also disclosed are e-Beam curable pressure sensitive adhesives made with the derivatizing agent and methods for adhering substrates with the pressure sensitive adhesive compositions.
Abstract:
Pressure sensitive adhesive (“PSA”) compositions comprising a polymer having at least one vinyl group and a Type I photoinitiator bound to the polymer. The polymer is derivatized with a derivatizing agent comprising a vinyl group. The PSA can be cured by exposure to ultraviolet radiation.
