Description

PC-7 ® is a tough job Epoxy formulation developed for maximum bonding power. Components A (grey) and B (black), when mixed, react to form a bond of tremendous strength. PC-7 ® formulation provides extended working time, giving user ample time to complete larger jobs, reposition work or make changes. High wet grab or tack of PC-7 epoxy paste ® makes overhead and sidewall work easy without drip or sag. PC7 epoxy paste ® demonstrates excellent chemical resistance to mild acids, caustics, detergents, gasoline, fuel oil, salt, and fresh water. PC7 epoxy paste ® will not bond to wax paper, TEFLON ®, polyethylene, and some soft plastics. Test area when in doubt.

Mixing Tips

Approximately equal amounts of A and B by volume, variations of either compound as high as 20% will not affect bond strength. When desirable, one part of A to two parts of B may be used to increases elasticity (expansion joints, etc.). In cold or cool temperatures, place PC-7 epoxy paste containers near heat prior to using. PC-7 ® mixes and spreads easier at 80°F than at 40°F. Any smooth flat surface is an excellent surface for mixing and working. A small putty knife or flexible artist's spatula are excellent tools for both mixing and applying PC-7®.

Directions

Using separate knives (remove amount needed from cans), mix equal parts of A (lt. grey) and B (black) on flat surface until uniform in color. Surfaces to be bonded must be free of dirt, oil, rust, etc. Denatured alcohol or lacquer thinner are excellent for removing oil, fingerprints, etc. Rough up surfaces for best results. Normally, no vice or clamp needed, Prop or tape heavy objects to a wall or ceiling. At 70°F (21°C) PC-7 epoxy paste will remain workable in excess of one hour and cures for service overnight. Cure will be much faster at higher temperature than at low.

Application

Apply PC-7 ® in any thickness to both sides of surface and bring together firmly. Be careful to insure that ample PC-7 epoxy paste ® remains between the contact surfaces. To bridge or reinforce larger holes, screen wire or glass cloth is excellent. To smooth out work, dip tool in lacquer thinner or denatured alcohol. After cure, paint, drill, machine, sand, file, or saw PC-7 ®. ADVISE – Do not subject to sustained heat in excess of 200° (93°C). PC-7 ® has strength far exceeding most materials on which used. Speed cure with artificial heat.
