Product Description of PERMABOND® TA4660
PERMABOND® TA4660 is a 2-part, 2:1 low odour, acrylic adhesive. It was developed for structural bonding of nylon/polyamide (filled and unfilled) without the need for any primers or additional surface treatment, such as plasma. TA4660 is also good for bonding nylon in combination with certain metals. It cures at room temperature and contains microbeads to control the bondline thickness for superior performance.
Features and benefits of PERMABOND® TA4660
- Excellent adhesion to nylon
- No primers required
- Full cure at room temperature
- Low odour
- Good temperature resistance
Surface Preparation for PERMABOND® TA4660
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
