PC-7 is the original tough job epoxy!
This paste epoxy was originally formulated more than 60 years ago for the maximum in bonding power. Professionals to the do-it-yourselfers select PC-7 because of its exceptional adhesion to metals, ceramics, masonry and many plastics. PC-7 is designed for permanent repairs. Where other adhesives fail… PC-7 won’t! Choose PC-7 if you want to: seal a crack in a wall, attach a hanger to a ceramic plaque, seal a leak in an oil pan, repair a granite monument, fix a leak in PVC pipe connection, create a multimedia sculpture, and thousands of other repairs. When mixed, part A (grey) and the hardener part B (black) react to form a bond of tremendous strength. The PC-7 formulation is slow curing, but slow can be a good thing especially for large tasks.
PC-7 is thick. Thick is good if you need to work vertically or want to hold an object in place. How thick? Thicker than peanut butter but not as thick as bubble gum.
Working time: 60 minutes
Cure time: 24 hours (tack free in 3 hours, 48 hours for full cure)
Why use a paste epoxy? Paste epoxies are for the heavy duty, permanent repairs. Paste epoxies give extra working time for large jobs and are the strongest epoxies in the PC-Products family of repair products. Your choice for critical repairs.
Easy mix The two parts are differently coloured, simply mix until you can no longer distinguish between the two colours. Unlike most epoxies, PC-7 does not require precisely a 1:1 mix ratio. Plus or minus 25% A or B will not affect the performance.
Waterproof PC-7 is not only waterproof but has excellent chemical resistance to mild acids, caustics, detergents, gasoline, fuel oil, salt and fresh water.
Multipurpose Use PC-7 on fibreglass, concrete, wood, metals, brick, glass, block, ceramics, rubber and more. (Some surfaces may benefit from prepping before use.) It is easier to say what PC-7 will NOT bond to: Wax paper, teflon, plexiglass, vinyl and some softer plastics.
Finishing touches After PC-7 has cured it can be sawed, sanded, tapped, drilled, machined, filed and painted.
