For lubricant blenders and distributors, additive selection is where performance, compliance and cost converge. A gear oil must carry heavy loads without attacking copper; an engine oil must protect under high temperature while meeting low-ash expectations; a hydraulic fluid must stay clean and stable. Shenyang Lubticants Co.,ltd, operating the Bossed additive brand, supplies single additives and compound additive packages that help formulators meet these demands across automotive, industrial, marine and railway applications.
A focused additive portfolio with practical depth
Founded in 2002, Shenyang Lubticants Co.,ltd is a joint-stock company specialising in the research, production, sales and after-sales service of lubricating oils, lubricant additives and related chemical products. The company covers 36,000 square meters in the Shenyang Economic and Technological Development Zone and holds ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018 certifications. In 2020 it joined forces with Qingdao Bossed Lubrication Technology Co., Ltd, a high-tech enterprise focused on nano-lubricant additives. The Bossed brand now covers more than ten single-agent chemical products and dozens of compound additives, with annual total output exceeding 20,000 tons. Products are sold across more than 20 provinces and cities in China and exported to more than 20 countries, including the United States, Germany, Japan and Southeast Asian nations.
Single additives for targeted performance
Antioxidants and metal deactivators. The range includes aromatic amine high-temperature antioxidants such as BSD-5057 and BSD-5067, thiophenol-type antioxidants BSD-503 and BSD-504, liquid hindered phenol BSD-502 and BSD-502A, and the multifunctional liquid additive BSD-406E. For copper protection, Bossed offers BSD-551 benzotriazole derivative, BSD-T539 oil-soluble metal deactivator and BSD-553 oil-soluble metal deactivator. The T539 and T553 heterocyclic derivative technology uses nitrogen-containing chemistry that can form a protective film on copper surfaces, combining metal deactivation, oxidation resistance and antiwear performance. In a 121 C copper corrosion test, 0.025% T553 or T539 with 3.0% T321H in base oil gave a 1a result. These products are used in transformer oils, gear oils, antiwear hydraulic oils, synthetic greases, metalworking fluids and turbine oils.
Extreme pressure and antiwear additives. The portfolio covers sulfurized isobutylene T321 and high-pressure T321H, odourless T321A, highly active sulfurized olefin T3240, phosphorus-nitrogen types BSD-3101 and BSD-3102, ashless extreme pressure additive BSD-3918, amine salt and acrylate types, nano lanthanum borate BSD-4815 and nano copper composite BSD-3610B. These products support gear oils, hydraulic oils, greases, engine oils and metalworking fluids at treat rates typically between 0.1% and 5.0%, depending on the application and performance target.
Ashless EP additive BSD-3918. This phosphorus-nitrogen additive is produced from phosphorus pentoxide, higher fatty alcohols and long-chain fatty amines. It is designed to deliver extreme pressure, antiwear, corrosion inhibition, rust protection and friction modification, with light colour, good oil solubility and good compatibility. At a 1.0% treat rate in 500N base oil, BSD-3918 achieved a PB value of 152 kg, a weld load of 200 kg, a four-ball wear scar diameter of 0.34 mm and a copper corrosion result of 1a at 121 C for 3 h. It is suitable for vehicle gear oils, industrial gear oils, hydraulic oils and other industrial equipment oils, and it shows strong compatibility with sulfurized isobutylene in sulfur-phosphorus gear oil systems.
Compound packages that simplify formulation
Bossed compound additives are pre-formulated packages designed for specific finished lubricant performance levels. The automotive range includes gasoline engine oil packages from SJ/SL through SM/SN, SP and ACEA A3/B4, plus high-performance packages for Euro and Chinese VI requirements such as SP, ACEA C2/C3/C5/C6 and GF-6A. Diesel engine oil packages cover CF-4, CH-4, CI-4, CJ-4 and CK-4. There are also dual-fuel, low-ash natural gas, motorcycle and air-cooled or water-cooled two-stroke packages. Marine packages cover medium-speed cylinder piston engine oils, system oils and cylinder oils at multiple TBN levels. Railway locomotive oils are available in fourth- and fifth-generation packages.
For driveline and industrial applications, gear oil packages cover GL-4 and GL-5, CKC and CKD, including odourless, high-phosphorus, economical and low-odour heavy-duty options. Hydraulic oil packages include zinc-containing and ashless antiwear types, plus grades for light metals without stains. Industrial and special oil packages cover dual-purpose and multi-purpose oils, hydraulic transmission oils, screw air compressor oils, guide rail oils, automatic transmission fluid, continuously variable transmission fluid, turbine oils, vacuum pump oils, high-temperature chain oils, heat-transfer oils, quenching oils, deep-hole drilling oils, rust preventive oils and organic antifreeze coolant packages.
Where these additives prove their value
The practical value is in the application. Gear oil blenders can use T321, T321H, T321A or T3918 with a metal deactivator to balance extreme pressure protection and copper compatibility. Engine oil formulators can select a compound package for gasoline, diesel, dual-fuel or natural gas service, supported by antioxidants and friction-reducing additives. Industrial lubricant producers can use compound packages for hydraulic, turbine, compressor, heat-transfer, quenching, rust preventive and metalworking fluids. Marine and railway operators benefit from packages built for medium-speed engines, cylinder lubrication and locomotive service.
The product photographs show clear, amber and darker liquid samples in labelled bottles, along with drum storage and plant equipment, illustrating the liquid form and packaging scope of the range. This matters to buyers who need consistent handling, blending and storage across a broad additive line.
Quality, technical support and export experience
Shenyang Lubticants Co.,ltd has been awarded the title of Shenyang Star Enterprise for five consecutive years. Its technical team and production processes support product quality at a leading industry level. The company follows a green and high-quality development philosophy and provides professional lubrication solutions and technical support to customers. Export experience across the United States, Germany, Japan and Southeast Asia helps the team respond to international documentation, packaging and application questions.
A strong proof point is the BSD-78662 heavy-duty vehicle gear oil package, built around T3918 and T321 as core products. This fourth-generation sulfur-phosphorus heavy-duty gear oil passed the L-42, L-37-1, L-60-1 and L-33-1 bench tests at Southwest Research Institute in the United States. This gives overseas buyers a concrete reference when evaluating ashless EP and metal deactivator technology for severe-duty driveline fluids.
A practical path for overseas buyers
Start with the finished lubricant specification, base oil type, target performance level and the metal alloys in contact. From there, Bossed can propose a single additive, a combination of single additives or a compound package with a recommended treat rate. Buyers can evaluate samples in their own formulations, review technical data and then scale to commercial orders. For distributors, the breadth of the catalogue means one supplier can cover automotive, industrial, marine and railway additive needs.
