2、VE, TWO SIDED, WSB-M3G221-A ACRYLIC, MEDIUM TACK, INTERIOR 1. SCOPE The material defined by this specification is a two sided acrylic based pressure sensitive adhesive film with a medium to firm tack. One side is protected by a release liner. 2. APPLICATION This specification was released originally
3、 for material to bond flexible (PVC) foam to interior trim substrates. Prior to approval for other applications, the performance of the tape must be verified on the intended substrates to the requirements of the specifications and requirements defined in any associated component or assembly specific
