Functional V-422

 Functional V-422 is an additive that confers a tack or stringiness to a lubricant.

It is used to provide adherence in fluid lubricants and stringiness in greases.

Functional V-422 is NSF approved (120906, HX-1, HX-2).

For non-food-grade applications, we recommend Functional V-178, or, where superior thermal and shear stability are needed, Functional V-188. 

Typical treatment levels are 0.5-1.5% in fluid lubricants and up to 2.5% in greases, where shear and high temperatures may be encountered during processing. Since tackiness and stringiness are subjective properties that lack standardized test methods and since like other polyisobutylene tackifiers, V-422 is subject to degradation by shear and heat.  The required treatment level is best determined by experimentation by the user

• Due to the viscosity of V-422, elevated temperature (approximately 150°F) can facilitate handling.
• Temperatures over about 200°F may lead to degradation of tackiness and viscosity.
• In greases, we recommend adding V-422 last, to minimize shear degradation during milling.
• Safe handling precautions are the same as those to be taken with the base oil
