Silane coupling agent modified treatment greatly improves the dispersion stability in water-based resin systems, avoiding sedimentation and caking of filler; high-temperature calcination optimizes crystal grain structure, improving the covering power and anti-ultraviolet aging performance of coatings; moderate oil absorption adapts to the formula viscosity requirements of water-based coatings, improving construction fluidity; low water absorption avoids thickening problems in coating systems, ensuring storage stability of coatings.
The median particle size d50 is 3.2μm, whiteness deviation ≤0.8%, modification grafting rate ≥1.2%, packaged in 1 Metric Ton cartons. The production process meets VOC emission standards, no heavy metal residues, and complies with EU REACH regulations, providing safe and environmentally friendly fillers for water-based paint production.
Filling and covering materials for interior and exterior wall latex paint, waterborne industrial anti-corrosion paint, waterborne wood paint and waterborne floor paint; production lines of home improvement coatings; industrial painting workshops, providing stable and high-performance fillers for water-based coating production.
