Less Energy, Same Results
Reduced costs at a sustained level of quality. That's what the market exacts from product developers right now. Meeting that expectation to a tee are two new products brought forth by Evonik's Crosslinkers Business Line in the market segment Coatings, Adhesives and Printing Inks: Vestagon EP-HA 376 and Vestagon EP-SC 5050.
With the introduction of Vestagon EP-HA 376, Crosslinkers is expanding its product range of hydroxyalkylamide chemicals. This cross-linking agent is used predominantly in powder coatings that are applied by stoving in directly fired gas furnaces. Its advantage over previous products is that, when it hardens in the furnace, it substantially reduces yellowing in white or light colors and thus strongly enhances color stability.
Vestagon EP-SC 5050 is a second-generation catalyst for hardening polyurethane powder coatings at low temperatures. This new catalyst can accelerate matted hybrid powder coatings to achieve the same matting effect at far lower temperatures of around 150 to 200 °C. In addition this product expands the bandwidth of simultaneous hardening of thin and thick substrates while preventing the so-called patchwork phenomenon on the end product, which is caused by variations in object temperature and component density.
