ER / EH Series Resins and Hardener

�

Resins (ER)

� ER-2 is a low cost single phase resin system that is designed for applications where structural performance is not required

�� above 120F.�� ER-2 resin system works well on fiberglass, carbon, and Kevlar reinforcements.

� 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.

� ER-4 is a higher performance version of ER-3.

� 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.

Hardeners

� EH-101 is the fastest cure hardener (15 min. pot life) and is excellent for joining and fairing.� Cures well at low temperatures.

� EH-102 is designed for laminating moderately large components which need very good overnight room temperature cure

�� and 2-3 hours working time.� Parts can be de-molded after 12 hours at 77 F without the typical epoxy brittle phase.

� EH-103 is a long potlife (200 min) hardener which sets overnight, but requires 120 F post cure to eliminate brittle phase in

�� cure.� Excellent hardener for large boating projects which may require 8 hours of working time

� EH-104 is the slowest hardener and has low skin irritation and is recommended for individuals whom are sensitive to epoxy

�� resin hardeners, and large projects that require up to 12 hours of working time.� Parts will set hard after 48 hours, but

�� require additional heat at 160 F for 4 hours to complete the cure.� Hardener is not recommended for cures below 160 F.
