PermaColor Window Film from Mactac
Optically clear film lasts up to 5 years outdoors.
Mactac’s new PermaColor PermaTrans is an optically clear, pressure-sensitive adhesive film for second-surface mounting. The film is designed to eliminate silvering over printed materials. It features a polyester-release liner on each side and is reportedly resistant to water, detergents, alcohol, and some aliphatic solvents. Durable up to 20 years indoors or 5 years outdoors, the material is suitable for applications such as backlit signage and face- or back-mounted transparencies on glass, acrylic, Plexiglas, and other clear substrates.
