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
million of minute structures in the lubricants base stocks,which contain a
highly polar core and disperse enormous amount of polar contaminants. These
contaminants are products of oxidation, which serves as precursors to varnish
carbon and sludge formation as well as ready-formed varnish/carbon/sludge
deposits. the dispersed contaminants are held in “solution” in the base stock
while already-formed deposits are cleaned off the metal are elastomer surfaces.Both
the suspended precursors and deposit 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.
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. OCN 9810 works with other anti-rust and anti-corrosion additives in
supreme way in formulations of industrial and automotive oils and greases.
DESCRIPTION: OCN-9810 is oil soluble ashless dispersant recommended for engine oils, thermic
fluids,quenching oils 0.5 to 1.5% w/w.
It gives better
performance at lower concentrations, Higher maximum protection
due to high thermal stability and also cost effective.
It has excellent reserved
alkalinity which protects oil degradation.Easily miscible and flowable liquid.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.
DOSAGE: OCN 9810 at 0.5 – 1.5% treat level or as per requirements of formulators.
