Application
Mainly for fluid-loss control plus partial thinning effect. Good resistance to high temperature, salt and calcium. Contributes to borehole stabilization, anti-caving and anti-sticking. Recommended dosage: 1%–5%.
Dosage Guidance
1%–5%.
Indicative range from technical documentation. Final dosage requires testing and evaluation of the fluid system.
Packaging & Storage
3-in-1 composite bags with PE liner, net 25 kg/bag. Cool dry ventilated storage. Avoid broken packages; slight moisture absorption does not impair performance.
