## Overview

PC-7 The Original Heavy Duty Epoxy Paste is a two-part, high-viscosity adhesive designed for demanding repairs. It offers a 60-minute working time and cures to a rock-hard, chemical-resistant bond with 2150 PSI tensile strength. Suitable for bonding, sealing, and filling a wide range of materials, it performs reliably from -20°F to 200°F, making it the go-to epoxy for professional-grade indoor and outdoor projects.

## Description

Product 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. 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.

Review: Great overall epoxy for projects that require no running and strong bonds. - This is a much more affordable replacement for JB Weld. It has a long 1 hour working time. It does take a good 24 hours to cure solidly. The first hour it is still malleable by using a alcohol to smooth out the surface. It cures rock hard if you mix it in the right proportions and is mixed thoroughly. It sands very easily. I use this for creating fillets on high powered rocket fins, both plywood or fiberglass. Its easy to work with. It does not run/slide like thinner epoxies which allows you to apply it to multiple locations on your project at the same time. It is pretty thick to mix but is a great product overall. It is super strong. Use tape to mask off the area you don't want it to come in contact with.
Review: Sticky and strong. Excellent stuff - Used this stuff to repair a pitted, rusty bulkhead door. Cleaned the rust to shiny bare metal (important!) with a grinder then smeared the epoxy on with a putty knife. Worked great. I highly recommend wearing disposable gloves cuz this stuff is thick and sticky. 50/50 mix makes measuring simple. Use a stiff knife on a board or other stiff surface. A paper cup won’t cut it! Mix well. Hardens in 24 hours if 70 degrees.

## Questions & Answers

**Q: I'm using this to fill a crack in a hot water boiler. There'll be about 12 lbs of pressure on it, and between 120-180 degrees F. Will this work?**
A: I have used this on the inside of pool pump housing that are made of fiberglass and it sealed the tiny crack perfectly and has held for almost two years now. Not sure if I would use it if any of that water is going to consumed by human or animals. 
Your sealing the outside of a tank, so rough it up good to give it something to hold onto and it should be fine..

**Q: Can you paint over before it's fully cured?**
A: You can paint over most everything but will the paint stay is the true question.  I would not try painting over the Epoxy until fully cured and lightly sanded.  Sanding give it a slight rough texture for the paint to stick to.  Epoxy putty cures in 24 hr.

**Q: Can this be used to adhere mosaics?**
A: PC-7 Epoxy works on many different substrates, including glass and ceramics. Depending on how you do your mosaics it should work great, the only problem might be the thickness of the epoxy paste. It has a consistency like cold peanut butter, but that also helps it adhere in vertical applications.

**Q: Will this product secure threaded rod in concrete for a heavy duty flag pole in winds up to 100 MPH?**
A: I have not used in concrete, but it is a fenominal product and I believe it would

### ⭐⭐⭐⭐⭐ Saved my Favorite Fountain!! Happy!!
*by G***S on July 3, 2025*

I thought I'd already had left a positive review for this, but Amazon keeps asking me to do one so here it is. Pros/Cons: I used this to repair my20 year old vase shaped with a small basin fountain that had developed leaks, and cracks. Also used an easy to cut screen patch (also left a review on that a month ago) that this product enabled me to adhere the screen. Adhesive quality has been great so far, very easy to use with a disposable glove, no tools needed. Important to apply it only after the water has been drained out completely. first and no moisture is left on the area you want to patch. Allow it to dry for two full days to cure before lightly sanding any rough edges. I gently removed the sanding dust with a wet paper towel and then refilled the fountain with water. My fountain had faded from the original dark black color to a fairly light gray over the 20 years in the sunlight. I had assumed the black color of this adhesive would stand out like crazy, but once I started the fountain again it darkened the vase fountain to black again and the product remained exactly the same color as before so it blended very well! Personally, there are no cons, only pros for how I used it and the results! Highly recommend it for small projects!
