DOWFROST™ Copper Inhibitor is a specialty, azole-based inhibitor package designed to boost the anticorrosion properties of a Dow propylene glycol heat transfer fluid.
DOWFROST™ Copper Inhibitor is intended to be added when the inhibitors in a heat transfer fluid system become depleted or low, resulting in heightened rust formation or system damage.
To ensure proper protection for your system and to maintain the balance of the inhibitor package, Dow offers free sample test kits to test your inhibitor levels.
