Sign Muscle is a crystal clear, tough, polymer coating that surface encapsulates the images and text printed variety of substrates creating extremely durable signs and labels for indoor and outdoor use. Sign Muscle, a liquid monomer, is applied to the substrate after printing and cured by UV light radiation creating a high strength bond.

The polymer coating resists most chemicals, abrasion, staining and repeated washing, weather, pollution etc.. The Sign Muscle surface is smooth and nonporous enabling easy cleaning with conventional industrial cleaners and it’s durability permits washing with high-pressure washing equipment. Unlike traditional laminated products used in the sign industry that rely on adhesives, Sign Muscle is a permanent coating that can’t delaminate. Due to it’s ultra-hard surface, Sign Muscle allows easy removal of graffiti (spray paint, felt marking pens, stickers, etc) without damage to the graphics and text. Print color integrity is significantly improved due to Sign Muscle’s UV inhibiting properties thereby extending the life of all signs and labels, particularly items in outdoor locations.
