Product Introduction
Permabond® A129 is a medium-strength, thixotropic anaerobic adhesive specifically designed for coarse threads. Its viscosity and strength characteristics also make it suitable as a flange sealant or for bonding co-axial joints. Its medium strength allows for easy disassembly with regular tools, making it ideal for maintenance applications.
PERMABOND® A129 Features
- Can be dismantled with normal tools
- Excellent chemical resistance
- Low shrinkage during cure
- Provides corrosion protection
PERMABOND® A129 Applications
- Coarse thread sealing
- Flange sealing
- Co-axial joint bonding
