Bonds Most Everything to Nearly Anything!
Description:
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.
***Note: PC-7® will not bond to wax paper, Teflon®, Polyethylene, and some other plastics. There are hundreds of plastics in thousands of combination. Test a small area when in doubt.

Directions:
Using separate knives to remove amount needed, mix equal parts A (grey) and B (black) on flat clean surface until uniform color is achieved. Surfaces to be bonded must be free of dirt, oil, rust, etc. For best results, rough up the surface PC-7® will be bonding to. Normally, no vice or clamp needed. Prop or tape heavy objects to a wall or ceiling.
Apply PC-7® Epoxy Paste in any thickness to both sides of surface and bring together firmly. Be careful to insure that ample amount of PC-7® remains between the contact surfaces. Use screen wire or fiberglass cloth to reinforce large voids and gaps.
Denatured alcohol is excellent for smoothing applied PC-7®. Also use Denatured alcohol to clean surfaces before applying.
After cure: Paint Drill, Machine, Sand, File, Tap, or Saw.

Approximately equal amounts of A and B by volume; variations of either component as high as 20%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°F than at 40 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®.
***Note: Most epoxies are temperature sensitive and will cure faster at higher temperatures and slower at cooler temperatures. Speed cure with artificial heat.
