摘要:
This disclosure is directed to an additive package for a lubricant composition that provides improved fluoropolymer compatibility. The additive package comprises a halide seal compatibility additive and a second seal compatibility additive. The disclosure is also directed to a lubricant composition comprising a base oil, a halide seal compatibility additive, and a second seal compatibility additive. The halide seal compatibility and the second seal compatibility additive improves the fluoropolymer seal compatibility of the resultant lubricant composition.
摘要:
The present invention relates to polyalkene amine formulations comprising at least one polyalkene amine in a solvent, having improved performance properties, especially improved low temperature properties; a process for preparing such formulations and the use of these formulations in fuel and lubricant compositions, in particular fuels, for improving the intake system-cleaning action of such fuels.
摘要:
Described are various formulations of lubricant additive composition comprising an additive base oil, a chlorinated paraffin, and a first antioxidant that can be used as a stand-alone lubricant or can be used in an additive package that can be added to another lubricant composition (e.g., an engine oil, a transmission fluid, a turbine oil, a gear oil, a grease, etc.). Also described are various engine oil composition comprising the lubricant additive composition.

摘要:
A fluid composition comprised of a fluorocarbon refrigerant, a hydrocarbon oil, and an alkylene oxide additive compound represented by the general formula (I): ##STR1## wherein R is hydrogen or a lower alkyl group and R' is an alkyl group, wherein R and R' contain 6 or more carbon atoms. The additive improves the thermal resistance of the oil in the presence of the refrigerant.
