SILSEP matting agents are synthetic amorphous silica in white powder form with porous structure, excellent optical properties and tight particle-size control (2–13 μm). All grades: whiteness 98, SiO₂ (dry basis) ≥99.9%, pH 6.5–7.5. Packaging: 10 kg paper bag.
Precipitated-process grade with high oil absorption (DBP 300–350 ml/100g) and 4–6 μm particle size. Excellent matting efficiency and cost-performance for thick-film, cost-sensitive systems. Recommended: furniture paint, pigmented wood systems, general industrial.
Gel-process grade, BET 290–350 m²/g, 4–6 μm, narrow particle-size distribution for clear systems. Comparable to ED2-type grades. Recommended: wood clearcoats, coil, industrial and plastic paint.
5–6 μm grade with high transparency and balanced matting/anti-settling behavior. Comparable to C805-type grades. Recommended: wood, coil, industrial and plastic paint.
Organically surface-treated 6–7 μm grade — improved slip, reduced anti-settling reliance, better gloss retention. Comparable to ED-30 / C7 / OK412-type grades. Recommended: premium wood finishes.
Ultra-fine 2–4 μm grade with high oil absorption (350–380 ml/100g) for smooth, uniform low-gloss films. Recommended: leather finishes and soft-feel systems.
4–5 μm grade tuned for plastic coatings — balanced matting and recoatability. Recommended: plastic paint.
Organically treated 6–8 μm grade for plastic, wood and waterborne paint. Comparable to OK520-type grades.
6–8 μm grade engineered for high-speed coil application and industrial paint lines — stable rheology at high shear.
Organically treated grade with controlled oil absorption (140–180 ml/100g) engineered for 100%-solids UV-cure systems where standard grades lose matting power.
