Solvent-Free Acrylic and Polyurethane Pressure-Sensitive Adhesives

Solvent-free acrylic and polyurethane pressure-sensitive adhesives (PSA) form very interesting new groups of polymers. The research and development of these polymers with self-adhesive properties is a quite interesting research field with full innovation and expected further exciting development in this area. Solvent-free acrylic and polyurethane PSA are still something of a speciality. They are photoreactive and UV-crosslinkable, and after crosslinking are characterized by sufficient thermal resistance, excellent moisture resistance and very good adhesion to wide range of typical surfaces.
