The role our kaolin plays in your formulation
Rheology & Viscosity Control
Fine-tunes flow behaviour for consistent application performance.
Sag Resistance
Helps sealants and adhesives hold shape on vertical and overhead surfaces.
Cost-in-Use Efficiency
Effective extender that reduces overall formulation cost.
Consistent Dispersion
Uniform particle size verified batch-to-batch in our in-house QC lab.
