New Coating System from TechLine America

TechLine America, a group of six Italian companies, has unveiled Naturall "powder-in-powder" polyester coating system, which reproduces wood grain, marble and other special effects on aluminum profiles and sheets. The patented process creates these patterns in a wide range of colors and textures, according to the company. The results can be smooth, wrinkled or matte finishes. The product allows customers to have advantages of polyester and kynar powder-coated aluminum, and its resistance to ultraviolet, weathering and abrasion.

The process requires a powder base color application that is partially cured, followed with a second, darker layer of polyester powder applied by screen printing, thus creating the wood pattern. A final curing of the two powder painted coats fuses them together.

The equipment for Naturall unique coating can be manual or automated. The typical production capacity is about 260 length per hour, and the line requires four workers, according to the company.
