2 Part Epoxy Canister Kit Item# 12001 – 12 per Case

Red Epoxy, a two-part heat-cured repair kit, effectively seals and repairs cracks and crevasses in metals and rigid plastics.


Ideal for use on vertical or horizontal surfaces, Red Epoxy proves effective on aluminum/aluminum alloys, cast irons, copper/copper alloys, magnesium/magnesium alloys, carbon and stainless steels, galvanized surfaces, and most rigid plastics, including PVC, etc. Widely used in HVAC, refrigeration, plumbing, automotive, marine, and manufacturing industries.

Ideal for any:

  • vertical or horizontal surfaces
  • aluminum/aluminum alloys
  • cast irons
  • copper/copper alloys
  • magnesium/magnesium alloys
  • carbon steels
  • stainless steels
  • galvanized surfaces

Used in many industries, including:

  • HVAC
  • Refrigeration
  • Plumbing
  • Automotive
  • Marine
  • Manufacturing

How to Use

Clean: Clean repair area using sandpaper or emery cloth to remove debris, then degrease with a solvent like mineral spirits, ensuring it dries completely before application. Do not apply Red Epoxy to a wet surface.

Apply: Apply equal amounts of resin from the red and white tubes onto provided foil tray.

Mix: Thoroughly mix the red and white parts until achieving a uniform red color. Once mixed, the resin remains viable for up to 4 hours.

Cover: Use mixed epoxy to cover the repair area adequately.

Heat: Slowly and uniformly heat the repaired area using a hot-air gun. Avoid concentrating heat in one spot to prevent overheating, charring, or excessive running of the repair. In this event, remove and start over.

Cure: Observe the color deepen from red to nearly a dark purple as heating progresses before turning gold. A uniform gold indicates a cure. Once gold, remove heat and allow repair to naturally cool to room temperature. Do NOT force cool as it will cause a weakened resin bond and may result in an incomplete cure. After repair has cooled, equipment can be returned to service immediately.

Sold by kit. See above for kit specifications.

How does it Work?

Initially, the red part (epoxy resin) is mixed with an equal part of the yellow part (hardener) forming a homogeneous mass. At this point, the reactants are brought together and allowed to develop sufficient compatibility before being used. In epoxy chemistry, the time required for the parts to become compatible is referred to as the induction time. Typically, an induction time of about 10 minutes is sufficient for Red Epoxy. Once the parts (or reactants) are brought together the reaction will slowly begin even without heat being applied. Eventually the reaction will result in a fully cured epoxy. Red Epoxy will fully cure without heat in 24 to 72 hours depending on temperature and humidity.

NOTE: when Red Epoxy is allowed to cure without heat it retains its deep red color. The period of time required for an epoxy mixture to become unworkable is referred to as the pot life. Red Epoxy has a pot life of about 4 hours. This means that Red Epoxy can be used for repairs up to 4 hours after mixing. Finally, the Red Epoxy mixture is heated and the reaction rate is accelerated. When the color changes from red to gold the product is completely cured.

Making Repairs with Red Epoxy is easy. Just follow these steps:

  1. Squeeze out a small amount of resin from the red tube and the white tube on any clean surface.
  2. Mix the two parts together with a clean spatula or stick into a uniform red color. This guarantees uniform mixture.
  3. For best adhesion, clean the repair area with sandpaper or emery cloth removing all loose scale, dirt or other foreign matter.
  4. Then clean the sanded area with a solvent degreaser such as mineral spirits to remove any residual oil or grease. Allow the solvent to evaporate to a dry surface. Do not apply Red Epoxy to a solvent-wet surface.
  5. Place a small amount of the prepared Red Epoxy to the break or area to be repaired. Be sure to use enough Red Epoxy to cover the area to be repaired.
  6. With a hot-air gun or propane torch, slowly heat the Red Epoxy and surrounding area. Use a slow brush strokes of hot air or heat from propane torch and pass directly over the repair area. NOTE: do not use a direct flame to heat the Red Epoxy to avoid overheating or charring. This heats the Red Epoxy and base material slowly and uniformly and does not develop hot spots in the patch. Overheating may result in charring or excessive running of the repair. If this occurs, remove material and start over.
  7. As the heating progresses, the red color will deepen and then fade to a gold color. When the entire patch is gold, remove the heat source and allow the work to cool to room temperature. CAUTION: do not force cool. Rapid contraction of the base material will weaken the resin bond and a complete cure may not occur. When the repair has cooled the equipment may be returned to service immediately.


Anywhere a small hole or crack exist Red Epoxy makes the best repair material. Red Epoxy does not run and it works on vertical surfaces. Red Epoxy makes an excellent threaded joint sealant, particularly for hard to seal chemicals and dissimilar materials. Red Epoxy has a very broad application range and is used in HVAC, refrigeration, plumbing, automotive, marine, process piping, petrochemical and manufacturing applications in industrial, commercial and institutional sectors.

Red Epoxy has successfully repaired aluminum evaporators, heating coils, hot water heater tanks, pipes, valves, fittings, metal components, automotive engines, radiators (both plastic and metal), condensate drip pans, exhaust systems, metal cooling towers, tanks and boiler tubes.
