Description

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. Its dual hydroxymethyl groups make it effective for controlled network formation in thermosetting formulations. In coatings and adhesives, it functions as a crosslinker that improves film cohesion and adhesion strength. This compound also enhances resistance to solvents and humidity in various industrial applications. Textile and leather finishing operations use it to impart dimensional stability and wrinkle resistance to treated fabrics and hides. Paper and pulp processors incorporate it into wet-strength resin formulations where controlled crosslink density directly affects end-product performance. Polymer formulators also evaluate it as a plasticizing comonomer. This application is particularly useful where flexibility and compatibility with hydroxyl-functional resins are required. Dimethylol glycol is typically supplied as a liquid at standard commercial concentrations for ease of use. Technical-grade material is the primary market form, with specifications aligned to industrial end-use requirements in coatings, textile, and paper applications. Buyers should confirm purity and active content directly. Stability parameters should also be verified with the supplier, as these vary between producers. This ensures the material meets the specific needs of the intended chemical manufacturing or processing application. Contact us for supply of Dimethylol glycol Request Quote
