Liquid Epoxy Resins

Grade EEW Viscosity Description (gr/eq) (mPa.s @ 25 °C)

Bisphenol A Epoxy Resins

D.E.R.TM 332 171-175 4000-6000 High purity diglycidyl ether of bisphenol A. Its high purity and low oligomer content assures uniform performance, exceptionally low viscosity and can provide improved elevated temperature properties over standard epoxy resins. This resin grade is mainly used in filament winding, electrical laminates and encapsulation applications.

D.E.R. 383 176-183 9000-10500 D.E.R. 383 epoxy resin is a low viscosity bisphenol A epoxy resin. Applications are similar to those of D.E.R. 331 liquid epoxy resin. D.E.R. 383 epoxy resin frequently crystallizes at room temperature. Heating to 50-55 °C restores the resin to a liquid state. Long-term warm storage may result in a slight discoloration but does not affect the resin performance.

D.E.R. 331 182-192 11000-14000 A widely used, general purpose liquid epoxy resin based on bisphenol A. It is recognized as a standard from which many variations have been developed.

D.E.R. 331J 186-190 12000-15000 Standard undiluted bisphenol A epoxy resin. Low chlorine content makes it suitable for electronics applications.

D.E.R. 317 192-203 16000-25000 High viscosity, fast reacting bisphenol A epoxy resin.

Low Viscosity Epoxy Blends

D.E.R. 354 167-174 3400-4200 Standard bisphenol F based epoxy resin of low viscosity, used for solvent-free coatings, concrete reinforcements, adhesives, electrical insulation and filament winding. This resin can provide improved resistance performance against solvents compared to standard bisphenol A liquid epoxy resins.

D.E.R. 351 169-181 4500-6500 D.E.R. 351 liquid epoxy resin is a low viscosity epoxy resin that combines the performance properties of standard bisphenol A epoxy resin with the low viscosity of bisphenol F epoxy resin. Applications include solvent-free coatings, tank-and pipe-linings, concrete reinforcements and also floorings, adhesives, electrical insulation and filament winding.

D.E.R. 352 172-181 5700-7700 Similar to D.E.R. 351 but with a higher viscosity specification.

Reactive Diluent Epoxy Blends

D.E.R. 321 180-188 500-700 D.E.R. 321 epoxy resin has extremely low viscosity which is advantageous for compounds containing large amount of filler. D.E.R. 321 has a cure rate similar to undiluted resins. The reactive diluent limits the solvent resistance, whereas an improved acid resistance can be observed. Main applications include floorings, groutings, concrete reinforcement, structural adhesives, water dispersible systems, crack injection and castings.

D.E.R. 324 195-204 600-800 D.E.R. 324 liquid epoxy resin offers low viscosity and low surface tension. The low surface tension explains why this resin wets the surface better, gives better adhesion and will have slightly lower viscosity at any given filler loading. The diluent increases pot-life, flexibility (impact resistance) and acid resistance but limits the solvent resistance. D.E.R. 324 liquid epoxy resin is prone to crystallization.

D.E.R. 353 190-200 800-1000 D.E.R. 353 liquid epoxy resin is a low viscosity epoxy resin with a very low crystallization tendency. The performance of D.E.R. 353 in ambient cure formulations is similar to those obtained when using D.E.R. 324 liquid epoxy resin.

D.E.R. 329 145-155 900-1300 D.E.R. 329 contains tri-functional reactive diluent, making it suitable for composites.

Flexible Epoxy Resins

D.E.R. 736 175-205 30-60 D.E.R. 736 is a short chain length polyglycol di-epoxide liquid resin. Its applications include coatings and adhesives for improved flexibility, elongation, and impact resistance.

D.E.R. 732 310-330 60-70 D.E.R. 732 is a long chain length polyglycol di-epoxide liquid resin. Its applications include coatings and adhesives for improved flexibility, elongation, and impact resistance.

Solid Epoxy Resins

D.E.R. 671 475-550 75-85 D.E.R. 671 solid epoxy resin is a standard “1-type” epoxy resin. Formulated with suitable hardeners, it forms an excellent base for many high quality chemical resistant coatings withstanding exposure to corrosive atmospheres containing a variety of chemical reagents, solvents or salt water.

D.E.R. 662E 590-630 87-93 D.E.R. 662E solid epoxy resin is a standard “2-type” epoxy resin developed for use mainly in powder coatings where it provides excellent flow. This epoxy resin grade is also employed to tailor the flexibility of lower molecular weight liquid coatings.

D.E.R. 663UK 787-813 90-96 Low molecular weight “3-type” epoxy resin with excellent flow for both decorative and functional coatings.

D.E.R. 663U 730-820 92-102 Low molecular weight “3-type” epoxy resin.

D.E.R. 663UE 740-800 98-104 Low molecular weight “3-type” epoxy resin for both pure epoxy and epoxy/polyester powder coatings requiring good gloss, smoothness and excellent flexibility.
