dvr Defoamer Antifoam

It is a Silicon based versatile liquid capable of effectively removing entrapped air from all types of water based mud under severe field conditions in a wide range of operations. It is utilized to reduce surface tension in water based drilling fluids as well as solids free work over and completion fluids. It is Effective at high temperature and at different PH of water based mud. It tolerates high concentration of salts.
