Abstract

See full text

Optically clear stretch releasing pressure sensitive adhesive films containing a silicone pressure sensitive adhesive composition and a tacky tab are provided. The pressure sensitive adhesive compositions are formed from elastomeric silicone polymer selected from the group consisting of urea-based silicone copolymers, oxamide-based silicone copolymers, amide-based silicone copolymers, urethane-based silicone copolymers, polydiorganosiloxane polymers, or mixtures of these copolymers. The pressure sensitive adhesive compositions may also contain an MQ tackifying resin. The pressure sensitive adhesive compositions may be used to form adhesive articles.
