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.
