PAC R & PAC L
PAC R: Filtration Control Additive
PAC R modified natural cellulosic polymer provides filtration control in most water-based drilling fluids.PAC L:Modified Natural Cellulosic Polymer
PAC L modified natural cellulosic polymer provides filtration control in most water-based drilling fluids without substantially increasing viscosity.
