Overview
Dipropylene glycol dimethyl ether , also known by its CAS 111109-77-4 , is a high-boiling glycol ether solvent used across industrial cleaning, coatings, and adhesive formulations.
Its low evaporation rate and strong solvency make it a preferred carrier and process solvent where controlled drying and compatibility with demanding formulations are required for manufacturers.
In printing and packaging, DPGDME functions as a slow-release solvent in ink formulations, helping to control flow and prevent premature drying on press during high-speed production cycles.
Coatings manufacturers incorporate it as a coalescing solvent in waterborne and solvent-borne systems, improving film formation and leveling in architectural and industrial finishes for better durability.
In adhesive and sealant production, it acts as a reactive diluent and carrier solvent, supporting viscosity adjustment without compromising bond performance or the integrity of the final product.
Industrial and institutional cleaning formulators use it as a degreasing solvent in hard-surface cleaners, where its low volatility reduces worker exposure while maintaining effective soil removal.
Dipropylene glycol dimethyl ether is supplied as a clear liquid in standard drum and IBC packaging. Technical grade is the primary commercial specification for most industrial applications.
Purity levels are typically at 98% or higher to ensure consistent performance. Bulk tanker supply is available for high-volume industrial customers requiring large scale chemical distribution.
