Viscosity Index Improver

It is an oil concentrate of an olefinic copolymer and is recommended primarily as a Viscosity Index Improver for crankcase lubricants particularly where excellent shear stability is desired.

As applies to all viscosity index improvers, there is some loss in viscosity and in viscosity index due to the shear forces encountered in engine operation. In this respect, it exhibits outstanding characteristics as evidenced by an average viscosity loss of 12 % at 100o C for SAE 15W-40 crankcase oils in over the road service.

In laboratory Caterpillar diesel engine Engine tests, it would be expected to perform at least comparable to the poly iso butylene type V.I. Improvers and superior to the polymeric ester types in regard to piston cleanliness. Being an all hydrocarbon material, it behaves in the same manner as the base oil component in MS Sequence engine tests. Multiviscosity oils containing VII have tendency for lower Octane Requirements Increase (ORI) than other V.I. Improvers.

Corrosion to the engine parts by acidic matters also can be prevented and its service time can be prolonged. Better compounding synergistic effect can be obtained with the addition of ashless dispersant, anti-oxidant and corrosion inhibitor. The quantity of the product to be added into lubricating oil is from 1.5% to 3.0% in formulating engine oil and 5 to 10 % in formulating Marine engine oils.

Dispersant

Introduction

Dispersants typically contain a hydrocarbon attached to an amine or alcohol containing polar group. The hydrocarbon "tail" serves to solubilize the molecule in lubricant base stock, while the polar group serves to attract the polar contaminants resulting from the lube breakdown. The dispersant forms millions of minute structures in the lubricant base stocks, which contain a highly polar core and disperse enormous amounts of polar contaminants. These contaminants are products of oxidation, which serves as precursors to varnish carbon and sludge formation as well as already-formed varnish/carbon/sludge deposits. The dispersed contaminants are held in "solution" in the basestock while already-formed deposits are cleaned off the metal and elastomer surfaces. Both the suspended precursors and deposits will readily pass through commonly used filters. Ultimately, when these cores are saturated, the dispersant can no longer pick up contaminants, so the oil must be drained. However, the oil should be drained well before this stage is achieved systems.

Performance

Dispersants can also emulsify water and can provide some secondary benefits in corrosion and rust protection. In addition, because of their surfactancy, dispersants are attracted to metal surfaces and may provide some measure of protection against rust and corrosion formation by coating the metal surface. It works with other anti-rust and anti-corrosion additives in supreme way in formulations of industrial and automotive oils and greases.

It is oil soluble ashless dispersant recommended for engine oils, themic fluids, quenching oils at 0.5 to 1.5 % w/w.

Features

It has following additional performance benefits.

	It gives better performance at lower concentrations and also cost effective.
	Higher maximum protection due to high thermal stability.
	Easily miscible and flowable liquid.
	It has excellent reserved alkalinity which protects oil degradation.
	Even at higher concentrations it does not allow gum and lacquer/varnish formations.
	It prevents catalytic effect of the metal at higher temperatures.
	Compatible with all conventional automotive and industrial additives.
