BYK’s latest additive solutions for radiation-curing coating systems, which will be unveiled at the upcoming European Coatings Show 2017 in Nuremberg, address these issues:
BYK-1788 and BYK-1799 are VOC-free defoamers for solvent-borne, high-solid and solvent-free systems with particular suitability for 100% UV systems. As a defoamer with broad compatibility, BYK-1788 is especially recommended for clear coat systems, whereas BYK-1799, on account of its strong defoaming action, can be seen to be pre-eminently suited for matt or pigmented coating systems and printing inks.
To systematically supplement its product portfolio in the area of wetting and dispersing additives, BYK has developed two new products that are characterized by their highly effective dispersion and stabilization of untreated and treated silica-based matting agents. Their use leads to a very significant reduction in viscosity, thus allowing a far larger quantity of matting agents to be incorporated. This also makes it possible to achieve a far more homogenous incorporation and orientation of the matting agents for deep matt UV-curing and conventional solvent-based wood and furniture coatings.
