Industry News, Science and Technology, and Market Insight
The shift to waterborne and 100% solids coatings to reduce VOCs and growing end-user expectations for greater coating performance and functionality are placing pressure on resin, additive, and pigment suppliers to develop novel materials that facilitate the formulation of low-VOC systems while imparting unique functionality. Additive manufacturers are taking on this challenge. Although used in minor quantities, additives can have a significant impact on the properties of coatings during processing, application, and after film formation. New products are being introduced regularly to help coating formulators achieve new performance attributes.
Evonik has launched two silicone-free flow and leveling additives. TEGO® Flow 375 and TEGO Flow 460 N have been developed for use in can and coil coatings. Both are listed worldwide, are suitable for direct contact with food, and are free from aromatics. For details, visit www.tego.de.
Acrylate Functional Silane
An activated acrylate functional silane has been introduced by Gelest. Sivate™ A200 can be used in adhesion promotion applications, including as primers for fiber optic cladding and coupling agents for light-cure acrylic nanocomposites. More information is available at www.gelest.com.
