Core Features and Applications
Structural characteristics: The molecule possesses both one carboxyl group and two active hydroxymethyl groups, with strong hydrophilicity and high reactivity.
Main applications: synthesis of waterborne polyurethane, waterborne polyester, epoxy resin adhesives; As the key chain extender of soap free self emulsifying system, stable lotion can be prepared without organic solvent.
Advantage comparison: Compared with similar DMPA, DMBA dissolves faster and has higher reaction efficiency. The resulting paint film has better water resistance and weather resistance, and reduces organic solvent residue. ‌‌

 
Storage and Security
Storage conditions: cool, dry, sealed, moisture-proof and light proof, away from strong oxidants and alkalis.
Safety reminder: It is irritating to the eyes, and protective equipment should be worn during operation; Avoid discharging into the environment. ‌‌
