- Technology
- Ready-to-Use Products
- Use Direction
Surfaces must be clean, dry and grease-free prior to bonding.; Shake cartridge (or stir bulk material) before use if separation has occurred.; Apply a thin bead of adhesive pre-mixed through a static mixer nozzle. (Alternatively bulk material can be dispensed via metered dispensing equipment).; Assemble components and clamp.; Maintain pressure until handling strength is achieved.; Allow 24 hours for adhesive to fully cure. Accelerated cure times may be achieved by heating.
- Benefits and Features
- Adhesion to a wide variety of substrates
- Cures at room temperature
- Easy 1:1 mix ratio
- Good resistance to impact and vibration
- Thixotropic, non-slump rheology
- 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.
