Moisture Content	10% max.
PH of 1% Solution	6.0 - 8.5
Degree of substitution	0.80 -0.95

 

Sample in 350ml solution
Viscometer dial reading at 600 r/min 2.20g in deionised water	minimum 30
Viscometer dial reading at 600 r/min 40g in 40 g/l salt solution	minimum 30
Viscometer dial reading at 600 r/min 2.50g in saturated salt water	minimum 30

Application
CMC HV is a cost-effective additive to reduce API filtration rate of many water based drilling fluids from freshwater to saturate saltwater. It increases and stabilizes viscosity to improve rheology, wellhole cleaning and suspension property by coating and encapsulating cuttings and solids of drilling fluids.
