SCOPE The material defined by these specifications is a clear, release liner backed, abrasion resistant urethane film with a water clear pressure sensitive adhesive. Films B1 - B4 include a clearcoat applied over the urethane film to prevent film s

A clean surface is recommended for tape application. A wetting solution (25% isopropyl alcohol/75% deionized water or S-802 Decal Lube or equiv
7、alent) may be recommended by the supplier to aid in application. Tape dimensions and premask (with or without) are specified on the engineering drawings. 3.
