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
- Excellent adhesion to nylon
- No primers required
- Full cure at room temperature
- Low odour
- Good temperature resistance
