Product Introduction
Permabond® LH197 is a highly flexible anaerobic material used for creating “formed in situ” gaskets between metal surfaces. It is particularly useful in applications involving dissimilar metals where differential thermal expansion may be a concern, making it ideal for use with soft metals like aluminum alloys.
PERMABOND® LH197 Features
- Flexible for easy removal
- Replaces all sizes of formed gaskets
- Ideal for bonding dissimilar metals
- Suitable for non-ferrous metals
- Can be dismantled with normal tools
PERMABOND® LH197 Applications
- Gasketing applications for dissimilar metals
- Applications requiring routine disassembly
- Ideal for soft metals like aluminum alloys
