Medium Cloud Point Glycol RXSOL MCPG is a broad cloud-point, wide molecular weight range, additive designed for medium-to-high salinity polyglycol systems. It can provide improved shale stability, lubricity, high-temperature filtration control, plus reduce dilution rates and bit balling.RXSOL MCPG is recommended for freshwater to seawater polyglycol systems. While polyglycols are most effective when used in conjunction with an inhibitive salt in non-dispersed polymer systems, they can be used as additives in most water-base systems.
