GENERAL INFORMATION
Product Description:
A two component paste grade system with extended working life for repairing and rebuilding machinery and equipment. Based on a silicon steel
alloy blended with high molecular weight reactive polymers and oligomers. Also used as a high strength structural adhesive for bonding or for
creation of irregular load bearing shims with good electrical insulation characteristics. Once cured, the repair is durable and fully machinable. For
use in Original Equipment Manufacture or repair situations.
Application Areas:
When mixed and applied as detailed in the Belzona Instructions for Use (IFU), the system is ideally suited for application to the following:
- Shafts - Keyways - Pipes
- Hydraulic rams - Engine blocks - Tanks
- Bearing housings - Casings - Flange faces
- Bushing fits - Leveling
