577 is a liquid inorganic rust inhibitor designed for treatment of steel and iron parts. 577 works by reacting with the surface of the steel and passivating it. There does not need to be any residual 577 left on the surface of the parts to provide protection. Parts can be welded, painted, plated or assembled without the additional step of removing the rust inhibitor.
- Provides in-process rust protection to iron or steel parts and to steel media during deburring operations.
- Provides rust protection for short-term storage after cleaning or mass finishing of iron or steel parts.
- Does not require parts to be re-cleaned before painting or heat treatment.
- Compatible with most alkaline compounds when simultaneous use is required.
