- Additional Information
This product is not recommended for use in contact with strong oxidizing materials. This product may affect some thermoplastics and users must check compatibility of the product with such substrates.
Information regarding the safe handling of this material may be obtained from the Safety Data Sheet.
Users are reminded that all materials, whether innocuous or not, should be handled in accordance with the principles of good industrial hygiene.- Surface Preparation
Surfaces should be clean, dry and grease-free before applying the adhesive. Permabond Cleaner A is recommended for the degreasing of most surfaces. Some metals such as aluminum, copper and its alloys will benefit from light abrasion with emery cloth (or similar), to remove the oxide layer.
- Directions for Use
- Surfaces must be clean, dry and grease-free.
- Apply a thin bead of adhesive pre-mixed through a static mixer nozzle.
- Assemble components and clamp.
- Maintain pressure until handling strength is achieved. The time required will vary according to the joint design and surfaces being bonded.
- Allow 24 hours for adhesive to fully cure.

Graph shows typical strength development of bonded components at 23°C. Curing at higher or lower temperatures may affect cure speed.
- Hot Strength
“Hot strength” shear strength tests performed on mild steel. Product fully cured at room temperature and conditioned to pull temperature for 30 minutes before testing.
TA452 can withstand higher temperatures for brief periods (such as for paint baking and wave soldering processes) providing the joint is not unduly stressed. The minimum temperature the cured adhesive can be exposed to is -55°C (-65°F) depending on the materials being bonded.
