PERMABOND® TA4246
PERMABOND® TA4246 is a 2-part, no-mix, room temperature curing structural adhesive. It is ideal for use on a wide variety of substrate materials and forms a very high strength structural bond with excellent environmental durability and chemical resistance. It has high peel strength and excellent impact resistance and can be used to replace rivets or welding to give a more lightweight, durable assembly. Use with Permabond® Initiator 46.

- Use Direction
Surfaces must be clean, dry and grease-free. Apply Initiator 46 to one surface. 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.
- Benefits and Features
- Adhesion to a wide variety of substrates
- Fast cure at room temperature
- No mix application
- Very high shear and peel strength
- Excellent impact strength
- Good chemical resistance
- 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..
