Verilok 552

Copolymeric latex additive for high salt and high BHCT wellbore cementing

Chemistry Type: Synthetic copolymer

Function(s): Cement Additives

Verilok 552 provides gas migration control for wellbore cements in high salt environments and high bottomhole circulating temperature (BHCT). It also acts as a fluid loss agent, suspension aid and stabilizer in cement slurries, as well as prevents dewatering and premature cement setting.

Previously sold under the Genceal CM 8400 name.
