New polyester provides flexibility with a tough exterior
Article Type: New products From: Pigment & Resin Technology, Volume 39, Issue 1
Valspar has introduced Granite, a polyester coating developed for prepainted metal products that require superior flexibility, scratch, and stain resistance as well as advanced adhesion performance when exposed to moist environments. These new polyester coatings are ideal for many coated coil applications including garage doors, truck trailer, rainware, and certain building panel applications. Granite coatings are available in a wide spectrum of colors with low, medium, or high gloss.
The Granite coating was designed to be used as a single coat application over aluminum. Lab and field tests prove this coating can achieve a 0T bend which allows for more design options. Scratch resistance tests show pencil hardness results up to 4H compared to the industry standard of F-2H. HDG steel, CRS, and Galvalume substrates can be coated with Granite coatings. A primer should be used over steel.
