Premix Phase:
- Charge 50 L water → slowly add HEC and mix 30 min.
- Add wetting, dispersing, defoamer, and pine oil.
- Add pigment/filler mix gradually under high-speed dispersion (30–45 min).
Post Dispersion:
- Add binder slowly under slow stirring.
- Add anti-settling agent (e.g., bentonite slurry) and HASE thickener slowly. Adjust viscosity to ~90–100 KU.
Final Make-Up:
- Add balance water, DEG, biocide, texanol, and thinner.
- Homogenize, filter, and pack.
