Part I: Product Description
Basic barium dinonylnaphthalene sulfonate (Chorus BSB) is a versatile oil-soluble anti-rust additive used in rust preventive formulations.
01. It has excellent anti-rust and anti-corrosion properties for ferrous metals.
02. It has good oil-soluble stability and excellent demulsibility.
03. It has an alkalinity reserve in the form of barium hydroxide Ba(OH)2 with a base value of approximately 45mgKOH/g to neutralize acidic components in lubricant oil.
04. Chorus BSB has a base value from barium hydroxide, which can result in slight corrosion to copper and some nonferrous metals.
05. In some extreme-pressure oil formulations, Chorus BSB may slightly affect the oil's extreme-pressure performance.
Countertype of KING NA-SUL BSB.
Part II: Advantages of Rust Inhibitor
Excellent salt spray protection.
Soluble and stable in petroleum oils and solvents.
Excellent water-displacing and water-separation.
Non-staining.
