ER-10: GENERAL EPOXY RESIN
Product Description
ER-10 is a single phase resin system that is designed for applications where high modulus and low cost are important. ER-10 resin system works well on all fiberglass, carbon, and Kevlar reinforcements.
Applications
- Snowboards
- Skis
- Molding applications that use heat to help assist fiber wetout
- 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.
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 180°F to achieve maximum cure and composite strength. In cases of free standing post-cures, the part should be heated slowly (20-30°F per 30 minute steps) to prevent warpage.
