DINITROL 3850 is a corrosion preventive fluid, designed for long-term protection against corrosion and, due to its residual hard film affords some protection against mechanical wear. DINITROL 3850 contains environmentally acceptable low aromatic solvents, which onceevaporated leaves a thick, brown waxy film. DINITROL 3850 is primarily designed for cavity protection but may also be used for storage, transport and underbody protection.
