PERMABOND® TA4204 is a 2-part, 1:1 toughened acrylic adhesive. It can be used to bond a wide variety of materials including metals, plastics, GRP, ceramics, wood and other substrates. It is convenient to use in an easy-to-dispense cartridge or it can be used bead on bead without a mixing nozzle. Bonds well to unprepared aluminium
This product may affect some thermoplastics and users must check compatibility of the product with such substrates
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 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. If using a cleaning solvent, allow 3-4 minutes to fully evaporate before applying adhesive.
2) Apply a thin bead of adhesive pre-mixed through a static mixer nozzle. If no mixing nozzle is being used, make sure one component is extruded on top of each other (not side by side).
3) Alternatively apply a thin layer of resin on one component and hardener on the other.
4)Assemble components and clamp.
5)Maintain pressure until handling strength is achieved. The time required will vary according to the joint design and surfaces being bonded.
6)Allow 24 hours for adhesive to fully cure. Accelerated cure times may be achieved by heating.
