Cortec®'s M-640 L is a liquid corrosion inhibiting additive for water and glycol-based heat exchange fluids. It protects ferrous and non-ferrous metals from corrosive contaminants. This product is an excellent replacement for silicates and phosphate/nitrite-based amine compounds. M-640 L is based on an organic-inorganic formulation designed for low level concentrations in field applications. M-640 L contains a unique combination of contact and vapor phase corrosion inhibitors that provide corrosion protection even in partially filled spaces. M-640 L is nitrite, chromate, silicate and heavy metal free.

Packaging:
Available in 5 gallon (19 liter) pails. Contact Us to get a quote for this product in drums.

Dosage:
The final concentration range for M-640 L under operating conditions is 2.0-2.5% by weight.

Typical Applications:
Use M-640 L as an additive to antifreeze and coolant fluids to replace nitrites, phosphates, amines and other types of restricted corrosion inhibitors. Can be used on closed loops during operation or layup. Metals protected include copper, brass, carbon steel, cast iron and aluminum.
