BYK-1640

BYK-1640 is a highly effective defoamer and antifoaming agent for aqueous coating systems. BYK-1640 is VOC-free and silicone-free making it suitable for various coating applications. BYK-1640 exhibits optimum performance at very low dosages, remains stable across wide pH range and can be added at any stage of production. BYK-1640 efficiently controls foam during production and application of coatings. Its unique polymer structure provides long-lasting antifoam effect. BYK-1640 is particularly useful in production of high-quality coatings for Advanced Materials where tight foam control is required to achieve uniform thickness and appearance of coated layers.
