Part A (epoxy resin portion) e.g. Stycast 2057 Part A ? Part B (hardener portion) e.g. Stycast 2057 Part B Two component matched urethane system ? Part A (polyol portion) e.g. Stycast U 2500 Part A ? Part B (isocyanate portion) e.g. Stycast U 2500 Part B Mix and match two part epoxy and silicone systems ? Resin side e.g. Stycast 2850FT ? Hardener side e.g. Catalyst 9 [also known as Cat 9] One component epoxy based system ? Stycast Exxx, Axxx, Gxxx, xxx, xxx-x, etc. 9Epoxy Systems 50 Epoxy Formulations Mix ratios: 1:1 to 20:1 Mixed viscosity: 200 cP to 1M cP Hardness: 23 (A) to 95 (D) Gel time: 2 minutes to months Dielectric Strength: up to 2000 volts/mil (20mil thickness) 10 Epoxy Systems Room Temperature Cure ?
