Stainless steel powder coating

aluminumfor the automotive industryISO 14001

Painting technology is one of the most widespread and traditional surface treatments in industry. The continuous development of the technology over decades has led to a variety of completely different application techniques. Collini primarily focusses on powder coating and cataphoresis (CDP) – a proven combination in the automotive industry. The design options in terms of colour, structure and gloss are limitless, while also providing optimal corrosion protection. In combination with hot-dip galvanising, powder coating provides maximum corrosion protection with many design options The powder particles, which are electrostatically charged in the powder gun, are blown onto the workpiece during powder coating. The workpiece is grounded so that there is a force of attraction, which makes the colour particles adhere. In the curing oven, they fuse at approx. 200 °C into a homogeneous, resistant powder coating layer (approx. 80 µm thick lacquer layer). The hardening or cross-linking that matches the component results in a perfect coating in terms of mechanical and chemical resistance. By selecting the appropriate type of powder, UV stability can be influenced. The colour hue, surface structures and gloss levels can be freely selected. The gradations from a smooth to a fine to a coarse structure have an influence on the tactile sensation, while the gloss levels, from high gloss to dull matt, complement the desired visual impression. Special effects, such as metallic, hammered or glaze effects complete the extensive range of design options.
