Overview
2,2-Dimethylolbutanoic acid (CAS 10097-02-6 ), commonly abbreviated as DMBA, is a difunctional hydroxyl acid monomer used to introduce ionic or hydrophilic character into polymer backbones.
It enables water dispersibility in polyurethane and polyester systems without requiring external emulsifiers. DMBA is a primary building block in waterborne polyurethane dispersions (PUDs) for industrial use.
In these systems, its carboxyl group is neutralized with amines to create self-emulsifying resin systems for coatings and industrial adhesives. This process is essential for modern chemical manufacturing.
In two-component waterborne coatings, it contributes to crosslink density and film hardness while maintaining low VOC profiles demanded by modern formulation standards. This ensures high performance in various applications.
Sealant and elastomer manufacturers use DMBA to tune the hydrophilicity and adhesion performance of polyurethane prepolymers. This versatility makes it a staple in the specialty chemicals sector.
Specialty polymer producers also incorporate it into UV-curable and radiation-curable resin systems targeting graphic arts and packaging applications. It provides excellent stability and processing characteristics.
DMBA is supplied as a white crystalline powder. It is available in technical and high-purity grades, with specifications typically aligned to the requirements of polyurethane resin manufacturers.
Packaging ranges from small drums to bulk quantities suited to continuous production environments. Our logistics team ensures that all material meets rigorous industrial quality benchmarks for global shipping.
