Grace extinction powder C809 Water matte powder C809
Extinction powder C809 has an average particle size of 9NM, oil absorption value of 300G/100G, PH value of 3.3, porosity of 2.0ml/g, and packaging specification of 10KG/ package. Extinction powder C809 is an amorphous silica, white powder, free flow. Extinction powder C809 IS A SILICA extinction agent with high porosity and easy dispersion without surface treatment. It has universal characteristics and wide application range. It is mainly used in coil coating, general industrial paint and printing ink.
SYLOID C series extinction powder has high extinction efficiency, controllable performance, and requires very little addition, so the influence on mechanical properties, weather resistance and other coating properties is quite small. SYLOID C series products can be added with a high speed blender to correct gloss, or with other pigments using a blender or bead mill.
Extinction powder C809 has the same commonalities and characteristics as other extinction powders of SYLOID C series, such as: High shear stability, resistance to excessive grinding, no hard precipitation will form in the coating during storage, no effect on curing performance, no side effect on interlayer adhesion, smooth, wear-resistant high-quality surface, high transparency, no fog shadow formation, as little as possible on the mechanical properties of the coating (such as hardness or flexibility), the weatherability of the coating has little negative effect.
