This JB Weld Original ColdWeld Grey Epoxy (2 Pack 28.4g) is designed for users needing strong, permanent repairs on metal, automotive parts, and machinery. Its key benefit is a steel-reinforced formula offering up to 5020 PSI tensile strength with an extended 4-6 hour set time for precise application. A potential caveat is its longer curing period, which may not be suitable for urgent repairs.

The initial set time is 4–6 hours, during which the parts should be held in place. A full cure, achieving maximum strength, typically takes 24 hours.
It works well on most rigid plastics. However, it is not recommended for flexible plastics or those like polyethylene or Teflon. Always test on a small, inconspicuous area first.
You must mix equal amounts (by volume) of the resin and hardener. Stir them together thoroughly until a uniform grey color is achieved.
It provides a tensile strength of up to 5020 PSI when fully cured.
Yes, J-B Weld Original ColdWeld is designed to withstand high temperatures after curing, making it suitable for many automotive and machinery applications where heat is present.
Store unused epoxy in its original, tightly sealed tubes in a cool, dry place to maintain its effectiveness.
The resin is the base component, and the hardener is the activator. When mixed in equal parts, they undergo a chemical reaction that cures into a strong, solid material.
Ensure resin and hardener were mixed in equal parts and stirred thoroughly for the recommended time. Check that the ambient temperature is within the recommended range (typically 50-90°F or 10-32°C).
Verify that the surfaces were properly cleaned, degreased, and free from contaminants. Roughening the surfaces can significantly improve adhesion. Ensure the parts were held securely during the curing process.
Check the storage conditions; extreme cold can thicken the epoxy. Gently warm the tubes to room temperature if they have been stored in a cold environment. Ensure you are using both components correctly.
This is usually due to incomplete mixing. Ensure the resin and hardener are stirred until a uniform grey color is achieved before application.
Setup:
Compatibility:
This epoxy is ideal for bonding to most rigid surfaces, including steel, iron, aluminum, carbon steel, brass, concrete, ceramic, and many rigid plastics. It is not recommended for use on flexible materials or polyethylene/Teflon. Always test on an inconspicuous area if unsure.
Care:
Store unused epoxy in its original, tightly sealed tubes in a cool, dry place. Once mixed, there is no storage; use immediately. Clean tools and any excess uncured epoxy with denatured alcohol or acetone before it hardens.
