Barium dinonylnaphthalenesulfonate CAS 25619-56-1
Barium dinonylnaphthalenesulfonate T705 is a versatile, high-performance oil additive. Its strong oil solubility allows it to adhere firmly to metal surfaces, forming a uniform film that prevents oxygen and other harmful gases from contacting the metal surface, providing rust protection. It offers excellent lubricity and wear resistance, and its performance is stable even in wet conditions.

FAQ
- Q: What are the main applications of barium dinonylnaphthalenesulfonate?
A: It is a high-performance oil-soluble anti-rust and anti-corrosion additive. - Q: How is its solubility?
A: It has excellent oil solubility and can be dissolved in mineral oil, synthetic hydrocarbons, ester oils; it is insoluble in water. It is stable in oil-based systems and does not separate easily; it is not suitable for water-based systems. - Q: Storage conditions, shelf life?
A: Store it sealed in a cool and ventilated warehouse, avoiding direct sunlight and high temperatures (>60℃), and keeping it away from strong oxidants. The original packaging is sealed and has a shelf life of 24 months. The viscosity increases in low-temperature environments, and it returns to fluidity after heating, without affecting performance. - Q: Recommended packaging? MOQ & delivery time?
A: 200kg iron drums; 1000kg IBC tanker drums; small samples 100–500g. MOQ: 200kg; Delivery within 3–7 days for regular orders, and production can be arranged for large orders. - Q: Recommended dosage?
A: Adjust the dosage according to the anti-rust grade. Generally, it is 0.5–5%; for high-demand applications such as salt spray and marine storage, the dosage is higher. It is recommended that customers conduct small-scale tests in salt spray and humidity chambers.
