BT-S1 suspending aid
Overviews
BT-S1 additive is a suspending aid and free-water control agent which is effective up to 302oF(150oC)(the equivalent of SA-541TM Control Agent). When slurries containing BT-S1 suspending aid are heated to temperatures over 90°C, the material yields to suspend down hole solids. BT-S1 suspending aid counteracts the thermal thinning of cement slurries and enables them to be mixed more easily. The control agent has little effect on surface-mixing viscosity.
BT-S1 control agent has a shelf-life of up to 24 months and is not classified as hazardous waste by the Environmental Protection Agency.
