The Balancing Act: Soft and Hard Tg Components in Acrylic Pressure Sensitive Adhesives (PSAs)
Acrylic polymers are the most commonly used self-adhesives, having replaced many compounded natural or synthetic resins. Acrylic offers oxidative stability and resistance to some UV radiations, and are inherently tacky and can be adapted to a variety of uses by copolymerizing two or more monomers, including non-acrylates such as vinyl acetate, N-vinyl pyrrolidone, or N-vinyl…
