What BET surface area is ideal for wood coating matting agents?

For wood coating matting agents, a BET surface area of 250-320 m²/g is optimal. CensilMatt 3651C at ~290 m²/g delivers strong matting efficiency while maintaining excellent film transparency and smooth surface finish.

How does CensilMatt 3651C compare to ACEMATT OK-520?

CensilMatt 3651C (BET ~290 m²/g) offers higher matting efficiency and better film clarity compared to ACEMATT OK-520 (BET ~260 m²/g), with superior surface smoothness and competitive pricing.

What is the recommended dosage for matting agent in wood coatings?

Typically 2-5% by weight. For satin finish (30-40 GU): 2-3%. For deep matte (10-20 GU): 4-5%.

Is CensilMatt 3651C suitable for UV-cured coatings?

Yes. Fully compatible with UV-curable coating systems including UV acrylate, UV polyurethane, and hybrid UV formulations. Does not interfere with photoinitiator activity or UV cure speed.

What is the difference between precipitated silica and fumed silica for matting?

Precipitated silica has uniform spherical particles with narrow size distribution, lower cost, and easier dispersion. Fumed silica has chain-like nanostructures that are more expensive and increase viscosity more aggressively. For coating matting, precipitated silica is preferred.
