PRODUCT DESCRIPTION 

M-370 is a multimetal, corrosion preventive additive for water-based metalworking fluids, lubricants, cleaners and coatings during product manufacturing. 

This water-based additive utilizes VCI technology for maximum protection. 


M-370 is also available in: 

• M-370 NS, a surfactant-free version, which helps in some detergent formulations 

• M-370 HS, a high surfactant version for providing a source of a compatible surfactant with levels high enough to clean 

• M-370 C, which provides additional protection to cast parts and surfaces which are rough 



FEATURES 

• Water-soluble 

• Environmentally acceptable 

• Safe to apply 

• Prevents flash corrosion on metal surfaces 

• Very stable in hard water 

• Forms a hydrophobic film 

• Will pass through a 1 micron filter 

• Nitrite-free and phosphate ester-free 

• Non-flammable 

• Passes ASTM D-4627-86 (Test Method for Iron Chip Corrosion for Water-soluble Metalworking Fluids) at 2.0% by weight 

• Usually can be added at any stage of production 



TYPICAL APPLICATIONS 

• Coolants 

• Primer coatings
