BYK 333 is a highly effective surface additive. It provides a strong reduction of surface tension, thereby improving the wetting of critical substrates. BYK 333 is particularly recommended for improving the substrate wetting. It improves properties like anti-blocking, slip and gloss. BYK 333 avoids issues like cratering and improves performance in areas like wetting and adhesion. The additive can be incorporated during any stage of the production process, including post-addition. BYK 333 is very user-friendly and proven to give good results without stability or defect issues when used as per recommended levels.
