PC-7 is the tough job epoxy. This paste epoxy was formulated for maximum bonding power. When mixed, components A (grey) and B (black) reacts to form a bond of tremendous strength. PC-7 formulation provides extended working time, for large and critical jobs, which allow the user to reposition work or make changes. High "wet grab" or tack of PC-7 Paste Epoxy makes overhead and sidewall work easy without drip or sag. PC-7 demonstrates excellent chemical resistance to mild acids, caustics, detergents, gasoline, fuel oil, salt, and fresh water. Approximately equal amounts of A and B by volume; variations of either component as high as 20 percent will not affect the bond strength. When desirable, one part of A to two parts B may be used to increase elasticity (expansion joints, etc. ). In cold or cool temperatures, place PC-7 container near heat prior to using. PC-7 mixes and spreads easier at 80 degree F than at 40 degree F. Any clean smooth flat surface is an excellent surface for mixing and working. A small putty knife or flexible artist spatula are great tools for mixing and applying PC-7. Use with as adhesive: wood, metal (all types), glass, brick, block, rubber, concrete, stone, slate, fiberglass, tile, and more in any and all combinations; as sealant: oil, gas, water tanks, cellar cracks, pressure tanks, and plumbing leaks; as a filler: holes, castings, patterns, molds, voids, welds, steering wheels and much more. Work time (70 degree F): 60 minutes. Tack free cure time: 160 minutes. Cure for service: 24 hours. Maximum cure: 7 day. Gardner impact resistance: 160 in. /Lb. Conduction (electric): non conductive. Excellent thermal shock. Non toxic once cured. Heat range: -20 to 200 degree F.
