What is 2,2-Dimethylolbutanoic acid?
2,2-Dimethylolbutanoic acid (CAS 10097-02-6), abbreviated DMBA, is a difunctional hydroxyl acid monomer used to introduce ionic or hydrophilic character into polymer backbones.
Where is 2,2-Dimethylolbutanoic acid used?
- Waterborne polyurethane dispersions (PUDs) for industrial use
- Coatings and industrial adhesives: carboxyl group neutralized with amines to create self-emulsifying resin systems
- Two-component waterborne coatings: crosslink density and film hardness with low VOC profiles
- Sealants and elastomers: tuning hydrophilicity and adhesion of polyurethane prepolymers
- UV-curable and radiation-curable resins for graphic arts and packaging
- It enables water dispersibility in polyurethane and polyester systems without external emulsifiers.
Commercial specifications
- Technical and high-purity grades
- Specifications aligned to polyurethane resin manufacturers
- Packaging from small drums to bulk quantities
