820 Epoxy Info
We sell only the very best epoxy!
After reviewing & testing all leading epoxies, we found 820 epoxy to be the best. This is why we are proud to sell this outstanding product!
Summary:
– UV stable (all hardeners)
– Room temp & high temp cure (handles temp up to 215F)
– Post-curing compatible
– Very high tensile (breaking strength). One of the world’s strongest 2 part epoxies
– Low Viscosity (thinner epoxy)
– Available in Qt, Gal, 5Gal, & 55Gal drums
– Very low to no odor
– a professional epoxy that works exceptionally well for pros and hobbyists alike
The 820 Epoxy Laminating Systems are developed for the fabrication and repair of high-performance composite structures. They consist of one resin and a selection of three separate hardeners to suit your building or repair needs. The resin and hardener combinations produce low-viscosity mixtures with convenient volumetric mix ratios. In addition, the 820 Epoxy Laminating Systems are specially formulated for standard wet lay-up or resin-infusion operations requiring the highest degree of fabric wetting and air release attributes. The systems are specifically engineered to promote a high fiber-to-resin ratio and a greater interface with composite fabric(s), thereby resulting in lighter, stronger parts offering lower maintenance and long-term performance.
820 Epoxy Laminating Systems are UV-stabilized, ultra-low viscosity laminating system that is ideal for use in vacuum infusion processes or RTM applications. Use with Graphite, S-Glass, E-Glass or Kevlar fabrics. Produces strong, lightweight composite parts. They are specially formulated for standard wet lay-up or resin-infusion operations requiring the highest degree of fabric wetting and air release attributes.
We recommend curing 820 between 80F and 160F (the epoxy will stop curing below 70F) . We have not tested above 215F and temp below 72F are not recommended due to very long cure times. The 820 will get thick when they get cold. If stored below 60F it may become semi-solid (this does not hurt the resin); if this occurs, put the can in front of a space heater and the resin will become thin and clear again.
