ER-3: High Performance Epoxy Resin


 

 

   

Product Description

ER-3 is a high performance single phase resin system that is designed

for applications where high modulus and low viscosity are important.   ER-3 resin system works well on all fiberglass, carbon, and Kevlar reinforcements.

Processing

Mix resin and hardener thoroughly at specified ratio.  Resin can be heated slightly to lower viscosity.  Do not expose resin or hardener

to excessive moisture conditions until fully cured.  Post-cure resin to 180oF to achieve maximum cure and composite strength.  In cases

of free standing post-cures, the part should be heated slowly

(20-30oF per 30 minute steps) to prevent warpage.

Applications

Marine and hand laminating projects

Filament winding

RTM processes

Chemical resistant coatings

Hardeners

EH-101, 102, 103 or 104 laminating hardeners

 

If application requires high delamination resistance, two phase ‘DR’ series resins should be considered.
