DINITROL 977 is a semi-transparent, water-based and liquid corrosion protection for cavities in vehicles, trucks, buses and other premises or locations where corrosion protection is required. The product is water-repellent and has excellent penetration properties. After drying, a wax coating remains with good temperature resistance up to approx. +120 °C and is almost non-sticking. When DINITROL 977 heats up in a dry state due to the sun or engine heat, it does not emit the conventional smell of cavity waxes.
