HY-302 Self-Defoaming Acid/Alkali-Resistant Wetting Agent
HY-302 is a modified siloxane gemini surfactant for waterborne systems, combining wetting and penetration, defoaming and foam suppression, lubrication, abrasion resistance and long-term stability.
Product Features
Surface tension as low as 24mN/m with excellent wetting and penetration.
Non-foaming by itself and provides defoaming and foam suppression.
Outstanding oxidation resistance and high/low temperature resistance.
Excellent compatibility with water-glycol systems and can be compounded with dispersants and corrosion inhibitors.
Good compatibility with resins and additives, without affecting recoating processes.
