The M-540 premium quality additive is designed to help develop a corrosion inhibiting grease for use even in harsh salt spray conditions.
M-540 is formulated with proprietary technology to provide corrosion protection in bio-based and ester-based greases. It provides long-term protection, even in humid and salt-containing environments, such as coastal and offshore conditions, where the chance for condensation and corrosion increases.
When tested according to ASTM D5969 for rust prevention, grease that failed to prevent rust in a 5-percent seawater solution was able to pass the same test after M-540 was added. Another advantage of M-540 is that it not only provides corrosion protection to metals in direct contact with the grease, but it also provides corrosion protection to nearby metals in bearing housings not directly touching the grease, the company says.
