Acid Diversion Agent SDA-120
CategoryAcidizing Fluid Additives

Product Overview:

Acid diversion agent SDA-120 is an ampholytic surfactant with special structure. It can dramatically increase the solution viscosity in acidic condition, such that the acidifying solution thickens and used for the preparation of diversion acid. Compared to acid diversion agent SDA-90, acid diversion agent SDA-120 has better viscosity stability at high temperature.
