Product Introduction

With a tertiary carboxylic acid group and two reactive hydroxyl groups, 2,2-bis(hydroxymethyl)butanoic acid(CAS No.10097-02-6) is one single molecule that offers the functionalities of water-soluble polyurethane and polyester. Highly solubility in organic solvents. 10 times more soluble in acetone than dimethyl propanoic acid.

Dimethylolbutyric acid is widely used in the manufacture of water-based polyurethane(wbpu), polyester, epoxy resin and other adhesives. It has better solubility than DMPA in different solvents and is regarded as a new generation of green environmental protection Chain extenders(chain extensions), And internal emulsifiers for the production of water-soluble polyurethane adhesives, without the use of organic solvents, zero organic residues, no high melting point, slow dissolution, long reaction time, high energy consumption and other problems.

Features:

• Highly solubility in organic solvents.
• 10 times more soluble in acetone than dimethyl propanoic acid.
• Does not require N-Methyl Pyrrolidine as a co-solvent.
• Does not have a coagulation problem.
• Gives a clear solution after the reaction.

• Tasteless, free flowing white crystals

Some examples on the use of DMBA:

• (water soluble) polyurethane dispersions
• chemical building block
• photo chemicals
• printing inks
• alkyds & polyesters
