As a chemical for changing the wettability of the solid phase, RS-502 hydrophobizes the particles of the weighting agent and drilled particles, thereby preventing their sticking and precipitation, increases stability of temperature and rheology, the level of water loss and the stability of the emulsion, and also increases the resistance of the solution to contaminants
Concentration of the chemical for a fresh fluid varies from 2.85 to 11.4 kg/m3; approximately 0.18 kg/m3 is used for daily treatment of the mud (if needed).
