These coatings have a rough surface similar to sandpaper. The degree of surface roughness can be controlled by monitoring the coat thickness. In order to achieve a rougher surface, the color coat should be thinner than usual and must be cured completely. The level of gloss and roughness can be adjusted based on preference and the application requirements.
These coatings are available in all coating bases like polyester, epoxy polyester, polyurethane. In fact, PU-based sand texture powder coatings can be used to great advantage in aluminum door and window sector of industry as they can be given a wood-like decorative effect.
The ratio of virgin-to- recycled coating affects the roughness or smoothness of these coatings, therefore it is recommended to keep the ratio constant to ensure a uniform design.
