PERMABOND® TA4660 is a 2-part, 2:1 low odor, acrylic adhesive. It was developed for the 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 bond line thickness for superior performance.
Features & Benefits

- No primers required
- Full cure at room temperature
- Low odor
- Good temperature resistance
Surfaces it bonds: Nylon, Polyamides, Carbon Steel, Stainless Steel, Aluminum, Most other Metals, Wood, Ceramics, Rock, Concrete, Glass, Fiberglass
