Polyester-polyether hybrid urethane acrylate oligomer for UV curing pressure sensitive adhesives

Polyester-polyether hybrid urethane acrylate oligomer for UV curing pressure sensitive adhesives

The invention is a pressure sensitive adhesive (PSA) composition, which is the ultraviolet radiation (UV) cured reaction product of a polyester-polyether-based urethane acrylate, one or more acrylate monomers, and a UV photosensitizer. The polyester-polyether-based urethane acrylate is the reaction...

description The invention is a pressure sensitive adhesive (PSA) composition, which is the ultraviolet radiation (UV) cured reaction product of a polyester-polyether-based urethane acrylate, one or more acrylate monomers, and a UV photosensitizer. The polyester-polyether-based urethane acrylate is the reaction product of between about 50 and 90 wt-% of a polyester diol having a molecular weight ranging from about 500 to 3200; between about 10 and 50 wt-% of a polyether polyol having a molecular weight ranging from about 1000 to 6000; between about 1 and 5 wt-% of a hydroxy-functional acrylate; and a polyisocyanate.
