The technology
What makes a matting agent perform in waterborne systems
Performance in high-humidity waterborne coatings comes from surface chemistry and particle engineering — not just raw silica.
High-melt PE wax modification
Surface wax treatment prevents hard sedimentation in low-viscosity systems and delivers a fine, smooth touch.
Narrow particle-size control
Tight d50 control (3.5–9.0μm) balances transparency and matting efficiency for water-white clarity.
Matting + anti-settling combo
Paired with fumed-silica thixotropy for anti-settling stability across the waterborne window.
High-purity amorphous silica
Amorphous, high-purity dry basis — no crystalline silica — for zero haze on dark substrates.
