Corrosion Protection - DINITROL 77B

Coating Technology

DINITROL 77B DINITROL 77 B 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 77B is a corrosion protection fluid for long-lasting protection against corrosion, which also offers a certain level of protection against mechanical wear due to the remaining hard film.

The product contains environmentally friendly, low-aromatic solvents that leave a thick brown waxy film after evaporation. DINITROL 77B was primarily developed for cavity sealing, but is also suitable for long-lasting protection during storage and transport as well as for underbody protection.

The recommended application temperature for the product and the object in question is between 15 and 30 °C.

  • Low dry film thickness with high corrosion inhibition effect
  • Diverse options for application
  • Large-scale applications, adapted for Airless pump technology
