TEGO Airex 922 — Technical Profile
TEGO Airex 922 is a Silicone-free organic-based deaerator and defoamer for non-aqueous systems manufactured by Evonik Industries AG (Germany), part of the TEGO Airex product line. World's strongest for EP floors.
How It Works
TEGO Airex 922 destabilizes entrapped air bubbles (micro-foam and macro-foam) in the wet film by reducing the surface elasticity of bubble walls, causing them to drain, thin, and rupture. Deaeration (micro-bubble release) is the primary function — these are not traditional aqueous defoamers but film-applied air release agents.

Formulation Considerations
Airex 922 (silicone-free) is critical for epoxy floor coatings where silicone contamination prevents recoating. Airex 931 (fluorosilicone) is uniquely effective for pinhole prevention in thin-film applications.
