Avery Dennison SC900 Hi Tack is a 2.0 mil cast opaque vinyl film with a high-gloss finish and a high-tack permanent acrylic adhesive that delivers aggressive initial bond strength. The specialty adhesive is formulated for demanding, hard-to-stick surfaces such as low-energy plastics, textured and powder-coated substrates, painted aluminum (ACM/ACP), and recessed rivets where standard adhesives can lift. It is recommended for cut-vinyl graphics and lettering, fleet markings, industrial and outdoor signage, and graphics on textured surfaces. Cast construction provides conformability with up to 12-year outdoor durability (color dependent).
