FAQs

What is the maximum temperature this epoxy can withstand?

The JB Weld HighHeat Epoxy Putty is designed to withstand continuous heat up to 205°C (400°F).

How long does it take to set?

The epoxy putty begins to set in approximately 1 hour after mixing.

Can I drill or sand the epoxy after it cures?

Yes, once fully cured, the epoxy can be drilled, tapped, sanded, and painted.

What types of materials can I use this epoxy on?

This epoxy is ideal for repairing metal components. It is not recommended for use on plastics or other non-metallic materials.

How should I store the unused epoxy putty?

Store any unused portions in their original packaging in a cool, dry place away from direct sunlight.

What is the tensile strength of the epoxy?

The tensile strength is up to 800 PSI, with 600 PSI at elevated temperatures.

How do I clean up after using the putty?

Clean tools and hands immediately after use with soap and water before the epoxy cures.

Troubleshooting

Epoxy not hardening or curing slowly

Ensure both parts of the putty were mixed thoroughly and in the correct ratio. Check that the ambient temperature is within the recommended range for curing (typically above 10°C/50°F).

Poor adhesion to the surface

Verify that the repair surface was properly cleaned, dried, and free from contaminants like oil, grease, or rust. Roughening the surface before application can improve adhesion.

Difficulty in mixing the putty

Ensure you are using sufficient pressure to knead the putty. If the putty has become very stiff, it may be too old or have been stored improperly.

Pros and Cons

Pros

Excellent performance in high-heat environments up to 205°C.
Provides durable and strong bonds suitable for demanding applications.
Quick 1-hour set time speeds up repair processes.
Can be machined after curing for a professional finish.
Easy to mix and apply by hand.

Cons

Requires careful mixing within the 1-hour set time.
Strength may be reduced at maximum temperature limits.
Limited to metal repairs where high heat is a factor.

Setup, Compatibility & Care

Setup:

Ensure the surfaces to be repaired are clean, dry, and free from grease, oil, or rust. Lightly roughening the surface with sandpaper can improve adhesion.
Cut off the required amount of putty from both sticks.
Mix the two parts thoroughly by hand until a uniform grey color is achieved. This typically takes 2-3 minutes. Work relatively quickly as the product begins to set in about 1 hour.
Apply the mixed putty firmly to the prepared area, ensuring complete coverage and good contact.
Allow the epoxy to cure for the recommended time before subjecting it to stress or heat.

Compatibility:

This epoxy putty is designed for use on most metals, including steel, iron, and aluminum. It is not recommended for use on plastics or other non-metallic materials.

Care:

Store unused putty in its original packaging in a cool, dry place. Once mixed, the putty cannot be re-used. Clean tools and hands immediately after use with soap and water.
