A3215TB is a 60 mil, clear solid acrylic tape that is virtually invisible after application. When used to reduce or eliminate the use of mechanical fasteners in a joint, it can provide for aesthetically pleasing joint designs. Designed with a solid acrylic core, it can develop high performance bonds to reduce or replace conventional mechanical fasteners, rivets, liquid adhesives and welds. Once adhered it will increase in bond strength over time and its performance will enhance with elevated temperature. NORMOUNTÂ® Acrylic also has excellent weathering properties.
