M-535 is an ashless oil-based corrosion inhibiting formula designed for petroleum and synthetic lubricants in turbine, hydraulic, circulating, compressor, and gear systems during layup or intermittent operation. M-535 protects the system from corrosion caused by condensed moisture and trapped water that could otherwise lead to the failure of equipment components. Corrosion inhibitors in M-535 protect metal surfaces with which they are in direct contact and release molecules in the vapor phase. These Vapor phase Corrosion Inhibitors form a protective molecular layer on metal surfaces above the fluid level, allowing economical and efficient rust protection at a low dose. In addition, M-535 provides outstanding non staining properties and is effective in most hydro carbon based lubricants (including naphthenic, paraffinic, PAO, etc.). Therefore, it is an excellent choice for industrial lubricant applications that require rust protection during layup.

Package and Storage: M-535 is available in 5 gallon (19 L) plastic pails and 55 gallon (208 L) metal drums. To ensure best product
performance, store in original packaging, indoors, and out of direct sunlight at 40-100 °F (4-38 °C).
Shelf life: 2 years
