What is Dimethylol glycol?
Dimethylol glycol (CAS 3586-55-8), also known as ethylene glycol bis(semiformal), is a difunctional hydroxymethyl compound used as a reactive building block and crosslinking agent in polymer and resin systems.
Where is Dimethylol glycol used?
- Coatings and adhesives: crosslinker that improves film cohesion and adhesion strength
- Textile and leather finishing: imparts dimensional stability and wrinkle resistance
- Paper and pulp: wet-strength resin formulations where controlled crosslink density affects performance
- Polymer formulators evaluate it as a plasticizing comonomer.
Good to know: Buyers should confirm purity and active content directly; stability parameters vary between producers and should be verified with the supplier.
