TOFA is separated and distilled off from various natural oil stocks and often blended with other fats to provide a better fat profile to be used for several industrial chemical manufacturing processes. Especially for amide and bis-amide synthesis, combination of saturated and unsaturated fatty acid imparts low Tg and favors less crystallization. It can also be used for chain termination additive for various polymerization processes. Provides structural support between casing and wellbore. Acts as a barrier to prevent steel corrosion. Blocks oil, gas, or water from traveling through the annulus. Protects fresh water aquifers. Prevents the inflow of undesirable hydrocarbons. Mixed with retarders to slow down the setting process
