FQ High-Efficiency Dehydrating Anti-Rust Oil
Anti-rust treatment for steel parts after processing steps such as blackening and phosphating typically uses an oil immersion process. Drying treatment is required prior to oil immersion. This product is a high-efficiency dehydrating anti-rust oil containing high-performance antioxidants. Replacing traditional heating dehydration, it offers room-temperature dehydration, fast and efficient liquid displacement, and excellent anti-rust performance. It is also suitable for the post-treatment of powder metallurgy and oil-impregnated bearings.
