The increasing stringent environmental regulations are urging the demand for high-value, eco-friendly coatings. 100% UV coatings are known for their eco-friendly properties, releasing no volatile organic compounds (VOC). Low gloss, high transparency, 100% solvent free UV coatings is one of the fastest growing technologies for its fast curing speed, short circle time, improved manufacturing efficiency, and film property, and it’s highly recommended for semi-gloss and matt coating applications such as wood coatings for floor and furniture.
However, matting of UV coating is still quite challenging. In 100% UV system, a large amount of matting agent needs to be added in the formulation, the wetting and dispersing performance is critical as it’s difficult to make the balance between the acceptable viscosity and the targeted gloss level and desired film properties.
TEGO® Dispers 689, launched in 2018, is a high molecular weight dispersant for solvent free UV Matting system. It is 100% active matt content liquid providing excellent wetting, reduced viscosity and anti-sedimentation properties for matting agents. It is especially suitable for untreated matting agents that have good transparency but high sedimentation tendency.
Because of its excellent anti-sedimentation property, it allows users to lessen or eliminate the use of anti-sedimentation additives in their formulation – which is advantageous to the development of highly transparent matte coatings. Appearance of the coating with this tailor-made additive can offer a sensation of high quality matting surfaces.
“We are honored to again receive this award in recognition of our long term commitment to the advancement of coating industry through our innovative product solutions,” said Wei Yin, Vice President, Evonik Coating Additives Asia Pacific, “The stricter legislation creates opportunities for innovation and enhancement in UV matting technology. The award-winning TEGO® Dispers 689 is a perfect example to demonstrate our ability to drive innovative solutions to help formulators address the formulation challenges by leveraging our global and regional R&D network and decades of experiences in waterborne coating additive solutions.”
