Product Name:Dipropylene glycol diglycidyl ether
English Name:Dipropylene glycol diglycidyl ether
CAS No.:41638-13-5
Aliases:Bis(epoxypropyl) dipropylene glycol ether, DER 736, Reactive diluent for epoxy resins
Molecular Formula:C12H22O5
Physical Properties:Colorless to light yellow transparent liquid with low viscosity. Density approx. 1.06 g/cm³ (25°C), flash point above 130°C (closed cup), epoxy equivalent weight approx. 170–190 g/eq, viscosity approx. 20–60 mPa·s at 25°C. Soluble in most organic solvents, slightly soluble in water.
Uses:Used as a low-viscosity reactive diluent for epoxy resins, effectively reducing system viscosity and improving wetting of substrates. Widely applied in epoxy coatings, adhesives, composites, and electronic encapsulation materials. Also serves as a modifying and toughening component in potting compounds and floor coatings to enhance flexibility and impact resistance.
