中文1. Product Introduction
This product is composed of fatty acid metal salts, antioxidants, composite rust inhibitors, special surfactants and refined mineral oil. It has excellent rust resistance, moisture and heat superposition resistance, and washability. It is suitable for sealing and rust prevention of cold-rolled steel plates (coils) and galvanized steel plates (coils).
2. Product characteristics
1) Low viscosity, easy to spray, low oil consumption;
2) Good moisture and heat superposition resistance and rust resistance. Oiled steel plates and galvanized steel plates will not burn or rust after long-term bundling;
3) Good washability, can be removed with general alkaline degreasing agents;
4) It has excellent matching with the wet leveling liquid used in the leveling process of steel plates and galvanized steel plates.
