AVIC Hangte company  is a well - known enterprise in the lubricant field, dedicated to providing high - quality products and services for the manufacturing of aerospace, research institutions, aircraft carriers and ships. Among its many excellent products, No.2 protective oil is a star product, which has attracted much attention.

No.2 protective oil is blended from refined mineral base oil with the addition of viscosity index improvers, rust inhibitors, antioxidants, etc. It passed the technical appraisal organized by the General Staff in 1996 and has become one of the most widely used protective oils in the Chinese military.

This protective oil works through physical and chemical adsorption, forming a dense protective film on the metal surface. This film effectively prevents the metal from direct contact with the atmosphere, water film and other media, thus playing an 

excellent rust preventing role. As a brown oily liquid, it has excellent high and low temperature performance, which can meet the use requirements of most regions in China . Its open - flash point is not lower than 140℃, and the pour point is not 

higher than - 50℃ . With a kinematic viscosity at 40℃ of not less than 16.5mm²/s, it can provide rust protection for 3 to 6 months . If the metal parts are sealed with plastic film after being treated with the protective oil, the rust - proof time can be 

extended by 2 to 3 times .

CLP gun oil  is commonly known as gun - cleaning oil, which is suitable for the annual use in areas above - 30℃ . It can be used for the daily cleaning and maintenance of various parts of firearms, as well as short - term (within 1 month) protection . When mixed with gun lubricating grease in different proportions, it can be used for the long - term storage of weapons and various metal components (5 to 6 years) . In addition to firearms, it is also suitable for the daily cleaning and short - term protection of the exposed metal surfaces of other equipment, and can also be used for the long - term storage of weapons and metal spare parts when mixed with gun lubricating grease . It is also widely used in the anti - rust of copper, aluminum, other ferrous and non - ferrous metals, and mechanical parts during the processing stage .

The product has many advantages. It is low - toxic and environmentally friendly, meeting the modern industrial environmental protection standards, so it can be used safely by operators . The oil film is only 6μm thick, and it can form a film quickly after spraying or brushing, with no residue and no adhesion to sand and dust . What's more, it has a certain cleaning ability, which can remove more than 85% of rust, carbon deposits and gunpowder residues on the metal surface, avoiding acid corrosion .

In general, AVIC Hangte  No.2 protective oil, with its excellent performance and reliable quality, provides a strong guarantee for the rust prevention and maintenance of weapons and various metal equipment, and plays an important role in the fields of national defense equipment and industrial manufacturing.
