Hydraulic Oil For Rust Preventive Oil
Rust-inhibiting oil, visually discernible by its reddish-brown hue, effectively safeguards metals from corrosion. Its primary role is to establish a barrier film atop metal surfaces, impeding the penetration of oxygen and moisture, thereby forestalling oxidation and the onset of rust.
Product Details：Hydraulic Oil For Rust Preventive Oil
Rust preventative oil, primarily formulated with oil-soluble inhibitors, base oil, and supplementary additives, can be administered onto metal surfaces through coating, immersion, or spraying methods. It finds extensive application in industries such as automobiles, machinery, shipping, electronics, and more, safeguarding metallic components from oxidative degradation.

1. Specifications: SH/T 0692-2000(2007)
2. Characteristics:
(1) Rust preventive oils can form a dense protective film on the metal surface, effectively insulating it from oxygen and moisture, thus significantly reducing the corrosion rate of the metal, or even bringing the corrosion rate down to zero.
(2) Different types of rust preventive oils, such as thin-layer rust preventive oils, replacement rust preventive oils, sealing rust preventive oils, etc., are suitable for different rust prevention needs, and can provide long-term and stable rust prevention effects.
3. Application scope:
(1) Preventing metal surfaces from rusting or corroding, particularly in damp or saline conditions, thereby prolonging the lifespan and preserving the quality of metal products.
(2) Serving as a protective barrier, sealing the metal surface to shield it from moisture, oxygen, and other corrosive elements.
(3) Application in the automotive sector to safeguard car body panels, engines, and other metallic components during storage or transportation.
(4) Utilization in machinery manufacturing to preserve equipment parts and tools prior to assembly or shipment.
(5) Assisting in maintaining the aesthetic appearance of metal objects by hindering the development of rust stains or discoloration.
(6) Employment in marine settings to protect ship hulls, anchors, and other submerged metal structures from corrosion.
(7) Adoption in the construction industry to safeguard ironworks, steel beams, and other metal structures during construction and before painting.
(8) Functioning as a temporary coating for metal surfaces awaiting further processing or finishing stages.
