DOWFROST™ Iron Inhibitor is a specialty dipotassium hydrogen phosphate based inhibitor designed to boost anti-corrosion properties for system protection.
DOWFROST™ Iron Inhibitor is a specialty additive intended to be added when the inhibitors in heat transfer fluids become low or depleted. DOWFROST™ Iron Inhibitor is formulated to ensure proper protection for propylene glycol thermal transfer solutions and to maintain the balance of the inhibitor package; Dow offers free sample test kits to test your inhibitor levels.
