It can also be used on canvas and other flexible face stocks to mask large areas cost effectively and provide easy removability. Additional features include, clean, quick, trouble free cutting with most plotters. Fast, easy weeding and a textured surface to help reduce over spray problems. The matte transparent film allows for quick, easy positioning. Stock Number CM8448 48” x 164 ft.

Shelf Life Two years when stored between 55° to 78°F (15° to 25°C) and 40%-50% relative humidity in its original package. Recommendations Removability will vary from surface to surface. Removal at slow speeds and at a 90° angle provides the best result from most surfaces. The above suggestions should be followed with air-dry paint systems. For those requiring heat to dry, removal of the mask while still warm is best. Bake temperatures above 140°F (60°C) are not recommended. Solvent compositions of paints vary. Compatibility with MACmask should be evaluated prior to use. Improper removal of paint solvents may degrade adhesive performance. It is critical that recommended drying procedures for each paint be followed. In all cases, we recommend the mask be removed within four hours maximum, following application to the substrate.
