AgeSin® DF-D9202S (similar to Tego Airex 920) is a non-silicone polymeric defoamer and deaerator designed to eliminate air bubbles generated during production, packaging, and application of coatings. It provides outstanding defoaming and air-release performance, especially in UV-curable systems. The additive suppresses bubble formation at an early stage, helps trapped air escape from the film, and prevents surface defects. It is particularly suitable for curtain coating applications without causing film breaks.
