Application of Vinyl Decals: Our standard vinyl is a plasticized, flexible, 4 mil film, coated with a pressure-sensitive adhesive. Vinyls are scuff-resistant and ultraviolet-resistant, so they will withstand outdoor use. Application temperatures for vinyl material and adhesives range from +35°F to +185°F. Once applied, vinyl will adhere in temperatures between -50°F to +185° F.
