Permabond® A129 is a medium-strength thixotropic (non-drip) anaerobic adhesive. It is specifically designed for use on coarse threads. Because of its viscosity and its strength characteristics, it may also be used as a flange sealant or for bonding co-axial joints. Its medium- strength also means that it may be dismantled for maintenance with normal tools.
FEATURES AND BENEFITS
- Can be dismantled with normal tools
- Excellent chemical resistance
- Low shrinkage during cure
- Provides corrosion protection
