HOSTADRILL EM 19142

HOSTADRILL EM 19142 is a primary emulsifier, based on a mixture of crude tall oil derivatives in hydrocarbons (containing aromatics) for oil-based muds. It promotes stabilization of water-in-oil emulsions in muds with densities up to 2.1 g/cm³ and temperatures up to 205°C (400°F), helping with electrical stability and reducing the mud's filtrate volume. For a good balance in the oil-based mud system, it is recommended to use HOSTADRILL EM 19142 in combination with the secondary emulsifier HOSTADRILL EM 17071, in addition of lime to obtain a calcium soap and improve system stability.
