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.

UV curing , solvent-free system.
Strong defoaming and deaerating effect throughout the whole coating process
Suppresses bubble generation at the initial stage
Facilitates air release from the coating film
Excellent compatibility in UV‑curable systems
No negative impact on adhesion
Does not cause film breaks in curtain coating applications
UV-curable coatings
UV inks
Suitable for other solvent-free systems where high-efficiency defoaming is required
Dosage: 0.1 – 1.0% of total coating weight
Recommended addition method: Add before grinding (under high shear) for best performance. For post‑addition, high shear mixing is necessary to ensure full effectiveness and minimize side effects.
