Overview of Belzona 1131
A 2-part epoxy metal repair composite with self-lubricating properties for creation of low friction surfaces and protection of lubrication systems from wear and seizure in the event of lubrication loss.
This 100% solids repair composite has a unique microporous structure which allows it to trap and hold lubricating oil, minimizing friction at start-up and improving the efficiency of mechanical equipment such as pumps. It has outstanding chemical resistance and will bond to almost any rigid surface without the need for hot work.
Key Benefits
Rapid return to service after application
Bonds strongly to virtually any rigid surface
Engineered to withstand demanding mechanical loads
Microporous structure traps oil to minimize friction
