TPS® 44
TPS® 44 is an inactive trisulfide sulfur donor additive (44% sulfur) showing excellent extreme-pressure and anti-wear properties, practically non-corrosive to copper & compatibility with mineral, synthetic base oils and greases.
Key properties: virtually colorless, clear liquid, with no particulates, free of unsatured hydrocarbon residues and compatible with a large range of closed-system formulations.
