4767-03-7 - Application:

2,2-Bis(hydroxymethyl)propionic Acid (DMPA) (CAS: 4767-03-7) is a versatile organic materials. it is used as water-based polyurethane chain extender, also make the polyurethane obtained from emulsifying properties, excellent stability can be made self-emulsifying aqueous polyurethane. For preparation a photosensitive resin and liquid crystal materials; for epoxy ester coatings, polyurethane elastomers and powder coatings; Preparation of magnetic recording materials and adhesives etc..
DMPA is a unique multifunctional hindered diol molecule with both hydroxyl and carboxyl groups. After neutralization with alkali, the free acid group can actively improve the water solubility or dispersion of the resin; Polar groups were introduced to improve the adhesion of coatings and the dyeing properties of synthetic fibers; Increase the alkali solubility of the coating. It can be used in water-soluble polyurethane system, water-soluble alkyd resin and polyester resin, epoxy ester coating, polyurethane elastomer and powder coating. It can also be applied to leather chemicals, liquid crystals, inks, food additives, adhesives and chemical industries. Especially in the manufacture of waterborne polyurethane and leather finishing agents, it is both a chain extender and a good self emulsifying property of polyurethane, which can greatly improve the stability of polyurethane emulsion and is widely used.
