Adhesive

This 100 micron cast blockout film is coated with acrylic pressure-sensitive adhesive which facilitates applications over a wide range of temperatures. Initial adhesion, ultimate adhesion and shrinkage properties have been balanced to create a product that is easy to apply, and performs to user expectations. Optimum application temperatures are between 60°F and 90°F (15°C and 32°C), but may be extended by special preparation i.e., heat gun at below 4°C and “wet” application at above 32°C.

Durability

Five (5) years, unprinted. Durability will be affected by any printing or clear coating, as well as actual exposure conditions and sign face maintenance.

Usage and Application Information

For best results on large, continuous-color signs, be sure to utilize material from identical rolls on the same sign face to assure perfect color reflection and transmission across the sign face.

When rejoining sheets or characters, avoid overlapping lm if possible. A preferable splice can be achieved utilizing a 45°-mitre cut after determining splice point by overlapping. Strip waste ends from top and bottom, then butt-angle cut together.

The angled butt splice gives best protection from uneven splices, preventing light leaks while avoiding overlaps that will create dark bands along splice edges.

When installing large graphics on glass, Plexiglas® or acrylic sign faces, it is useful to follow “wet” application techniques. This will reduce trapped air problems and aid in repositionability for proper registration. Care should be taken to thoroughly remove entrapped water through high squeegee pressure.
