ER-4: High Performance Epoxy Resin
ER-4 is a high performance single phase resin system that is designed
for applications where high modulus and low viscosity are important. ER-4 resin system works well on all fiberglass, carbon, and Kevlar reinforcements.
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 160oF 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.
Marine and hand laminating projects
Chemical resistant coatings
Viscosity is low enough to allow exceptional wetout at room temperature.
EH-101, 102, 103 or 104 laminating hardeners
If application requires high delamination resistance, two phase DR series resins should be considered.
Morphology: single continuous epoxy phase
