Nonionic resin oxyalkylate water in oil demulsifier Applications: Witbreak DRC-163 is a resin oxyalkylate. This emulsion-breaker works by effectively neutralizing the strength of the natural emulsifying agent, allowing the finely dispersed water droplets to coalesce. As the tiny water droplets merge into progressively larger and heavier drops, the water settles and the oil rapidly rises to the top. The result is a sharp, welldefined oil/water interface and bright, clean and marketable oil. Information provided by Nouryon |
