Rims can be the visual icing on the cake for any car. From glossy silver and matte black to any colour imaginable, nearly everything is possible to give rims a special appearance. The “magic formula” that make rims so an eye catcher is: powder coating. But aesthetics is only one side of the coin. The other side is much more important because powder coatings can also provide rims with great durability by giving them outstanding protection against acid rain, brake fluid spills, scratches, stone chip or just the daily exposure to UV radiation.
How does this protection actually work? A short retrospect: Once upon a time, whenever superior levelling combined with high reactivity was requested, powder coating formulators wouldn't take a polyurethane system into account. Those days are gone. Always at the forefront of developments, Evonik's Crosslinkers Business Line designed a polyurethane (PU) formulation for powder coatings based on VESTAGON® BF grades, which provides both excellent durability against environmental influences and a high surface quality.
VESTAGON® EP-BF 1350 improves UV, stone chip, and scratch resistance and helps powder-coated rims withstand chemical attack, e.g. from acid rain and brake fluids. It also gives rims a superior appearance with excellent gloss control.
VESTAGON® EP-BF 1350 is a blocking agent-free PU crosslinker, enabling the formulation of powder coatings with low emissions that comply with applicable regulatory requirements, cure at low temperatures (e.g. 160°C) and deliver unique levelling for perfect glossy surfaces.
With VESTAGON® EP-BF 1350 and a dedicated catalyst approach, polyurethane powder coatings are able to fulfil the highest performance demands required by the automotive industry.
