Glycerol Polyglycidyl Ether

Model Number

EJ-300, EJ-340

DESCRIPTION

Glyether Product EJ-300 is respectively glycerin polyglycidyl ether type epoxy resin that is compatible with various water-based resins (urea melamine resin, phenol resin, acryl emulsion, urethane emulsion, etc.). Addition of these modifiers improves water resistance, thermal resistance, and adhesion. EJ-300 polyglycidyl ether type epoxy resin is a water soluble, low viscosity, epoxy equivalent 135-150eq. EJ-300 provides excellent resistance to salt intrusion, and excellent adhesion to most common construction substrate. Addition of Glyether Product EJ-300 resin is ideal for adhesives, laminate, water soluble additives and wet lay-up applications. EJ-300 epoxy resin can be cured with various hardeners through the epoxide groups. Resulting in highly cross-linked thermoset polymers having good mechanical properties, good resistance to chemical and solvent resistance.

ADVANTAGES

• SOLUBLE IN WATER IN ANY CONCENTRATION, AND COMPATIBLE WITH WATER-BASED RESINS.

USES.

Glyether Product EJ-300 epoxy resin is a compatible with both bisphenol-A and other epoxy resins, adding highly cross-linked thermoset polymers having good resistance to chemical and solvent resistance. And improved impact strength to end products. Their epoxy functionality permits them to cross-link with hardeners and become part of the cured system.
