Acrylic adhesive TA4550 series

for metalsingle-componentfor bonding

PERMABOND® TA4550 is a 2-part, 2:1 low odour, acrylic adhesive. It was developed for structural bonding of nylon/polyamide without the need for any primers or additional surface treatment, such as plasma. TA4550 is also good for bonding plastics, composites and metals. It cures rapidly at room temperature and is thixotropic (non-slump). The adhesive is highly toughened, which makes it suitable for applications involving impact and vibration Surface Preparation Surfaces should be clean, dry and grease-free before applying the adhesive. Surfaces may have traces of mold release agent present – wipe with isopropanol (IPA) solvent and allow to fully evaporate before bonding. If bonding to metal: some metals such as aluminium, copper and its alloys will benefit from light abrasion with emery cloth (or similar) to remove the oxide layer. Directions for Use 1) Surfaces must be clean, dry and grease-free prior to bonding. 2) Apply a thin bead of adhesive pre-mixed through a static mixer nozzle. 3) Assemble components and clamp. 4) Maintain pressure until handling strength is achieved. The time required will vary according to the joint design and surfaces being bonded. 5) Allow 24 hours for adhesive to fully cure. NB: Adhesive outside of a closed joint (i.e. excess material) will cure more slowly and may feel soft due to air contact. Adhesive inside the joint will cure solid. 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.
