The 820 Epoxy Laminating Systems are 100% solids systems developed for the fabrication and repair of high performance composite structures. The 820 Epoxy Laminating Systems 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.
