PERMABOND® TA439
PERMABOND® TA439 is a two component structural acrylic adhesive designed primarily for bonding metals, ferrites, ceramics and some plastics. The typical fixture time of is 20-40 seconds. The fast fixture time of TA439 makes it an ideal adhesive for high speed production lines. This product provides high strength, tough, durable bonds with good impact resistance and performs well in drop tests.

- Use Direction
Surfaces must be clean, dry and grease-free. Apply Initiator 41 to one surface (or Initiator 43 for use on plastics).; Apply adhesive to the other surface.; Assemble the components using sufficient force to spread the adhesive thinly. Parts should be bonded immediately and within a maximum of two hours of applying the Initiator.; Maintain pressure until handling strength is achieved. The time required will vary according to the joint design, gap and surfaces being bonded.; Allow 24 hours for adhesive to fully cure. Accelerated cure times may be achieved by heating.
- HIGHLIGHTS
TA439 is methacrylic acid free, this means it is suitable for use on sealed electric motors and will not cause corrosion to sensitive components. Use TA439 with Initiator 41 (or Initiator 43 for use on plastics).
- Benefits and Features
- Adhesion to a wide variety of substrates
- Fast cure at room temperature
- No mix application
- High shear and peel strength
- Good impact strength
- Good chemical resistance
- Non-corrosive formulation
- 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.
- 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.
- Environmental Resistance
All values were generated on as received steel lap shears as described in ISO4587. Adhesive was cured at room temperature for 48 hours prior to environmental exposure. Test pieces were assembled with no induced gap and subjected to continuous exposure for 1000 hours at the testing temperature and then the shear strength was tested at room temperature.
