UREA-BASED AND URETHANE-BASED PRESSURE SENSITIVE ADHESIVE BLENDS

摘要

Adhesive compositions include a blend of a non-siloxane polyurea-based polymer, a non-siloxane polyurethane-based polymer, or a blend of a non-siloxane polyurea-based and non-siloxane polyurethane-based with at least one (meth)acrylate-based pressure sensitive adhesive. The non-siloxane polyurea-based polymer or non-siloxane polyurethane-based polymer is free of free radically polymerized groups. The adhesive composition is a self-wetting, optically clear pressure sensitive adhesive. The adhesive compositions can be coated on substrates to form adhesive articles.
