Product Bulletin
VERSACOAT VERSACOAT organic surfactant is a multi-functional additive which
serves as an emulsifier and wetting agent in the VERSA oil mud
systems. Secondary benefits include improved thermal stability
and High-Temperature, High-Pressure (HTHP) filtration control.
The product is effective over a wide temperature range and in the
presence of contaminants, and for reducing the adverse effects of
water contamination.
