Product Introduction

Dimethylol propionic acid -DMPA is a chemical compound that has the full IUPAC name of 2,2-bis(hydroxymethyl)propionic acid and is an organic compound with one carboxyl and two hydroxy groups.

[1] It has the CAS Registry Number of 4767-03-7.

• Regular: Standard grade Dimethylolpropionic Acid
• Low Sodium: Ideal for applications requiring insulation (i.e. insulated films & coatings)
• Fine: Smaller particle size for better quality of dispersions

Synonyms: Dimethylolpropionic acid; dihydroxypivalic acid;2,2-Dimethylol Propionic Acid; BIS-MPA; DMPA;
2,2-Dimethylolpropionic acid; 2,2-Bis(hydroxymethyl) propionic acid;dmpa acid;dmpa chemistry。

Dimethylol propionic acid -DMPA is an odorless free flowing white crystalline solid and essentially non-toxic. DMPA has two different functional groups hydroxyl and carboxylic acid so the molecule can be used for a wide variety of syntheses. In addition to reaction with other chemicals, DMPA can also react with itself to produce esters via esterification, as one example.

Dimethylolpropionic acid is multi-purpose organic raw material. It is one kind of chain extenders which used in water-based polyurethanes. It can also obtain self-emulsifying properties for polyurethane. 


• Tri-functional compound with 2 primary hydroxyl groups and 1 tertiary carboxyl group

• Neopentyl structure 

• Permits simplified processing by allowing the combining of all reactants in a single kettle charge

• Free acid group actively promotes resin water solubility or water dispersibility after neutralization with a base 

• Easily introduces a polar group to improve coating adhesion and synthetic fibre dye receptivity

• Increases the alkali solubility of deposited films.

Applications for Dimethylolpropionic Acid include:

• Polyurethane dispersions
• Water soluble alkyds and polyester resins
• Powder coatings
• Epoxy ester coatings
• Printing inks
• Lubricating oil additives


• Adhesion          • Carboxylic Acid Functional      • Hardness/High Tg     

• Hydrophilic      • Low Tg/Multi Functional          • Water Resistance

• Water Dispersibility             • Hydroxyl Functional
