Dimethylolbutanoic acid (DMBA)_DMBA

Dimethylolbutanoic acid (DMBA)


Description: 

DMBA is neopentyl carboxylic acid with two reactive hydroxymethyl groups. It is considered as a new generation of green & environment-friendly chain extender and internal emulsifier for water-based polyurethan. As a monomer for the process of modification, DMBA needs no organic solvents (water instead), therefore the production process is simpler and owns stabler and best performance. It solves the faults of DMPA such as high melting point, slow dissolution, long reaction time, high energy consumption, poor product performance, the need of organic solvents, big solvent residual volume and so on. Currently, it is the best multipurposed modified auxiliary (hydrophilic chain extender) of polyurethane, water-based resins, water-based adhesives, water-based paints and other water-based products
