Release Liner 0.003 in. (0.08 mm) Red / Black Printed Paper Colour White Approximate Density : Lb./ft.3 12 Foam Only (kg/cm3) (192) Shelf Life 36 months from date of despatch when stored in the original carton at 21°C (70°F) & 50 % Relative Humidity As shown on above table, greater weights can be supported if the load is applied after one hour adhesion build time. 1.a utility hook is adhered to a wall but nothing is hung from the hook for one hour. The hook can then hold a greater weight than if something had been hung from it immediately. 2. adhesive has good adhesion to most painted surfaces as well as to low surface energy plastics such as polypropylene and polystyrene while maintaining excellent adhesion to metals, glass and high surface energy plastics. adhesive will reach maximum adhesion in one hour. Adhesion to polyethylene will usually be dependent on special surface treatment. Because of additives in plastics and high solid paints, it is important for the user to evaluate individual applications for appropriate use and suitability. 3.Care should be used when bonding to surfaces with very low internal strength such as painted plaster board, fabric or cloth, wallpaper, blown vinyl etc since delamination of that surface may occur.
