HiTEC® 082

Alkylated Sulfone Seal Swell Agent

Key Performance Benefits

  • Metal Free
  • Chlorine Free
  • Good handling characteristics


HiTEC® 082 is a highly polar but relatively inert solvent which is used in a variety of applications where these properties are desirable. It may be used as an additive in lubricants in order to improve the solubility characteristics of other polar chemistry, and in order to prevent seals that the lubricant may contact from shrinking or from hardening.

Recommended Dosage

HiTEC® 082 is recommended between 0.5% wt. and 1.5% wt. in lubricants comprising high levels of group II, III or IV base oil to bring elastomer properties. Required treat rates may be influenced by a number of factors, including:

  • Base oil
  • Other additives present
  • Elastomer composition
  • Temperature
  • Application

Please contact your Afton Chemical representative for specific recommendations.
