Evonik's SPHERILEX® DP-0110 is an amorphous (crystal-free) precipitated silica with unique spherical particles and a narrow particle size distribution.
Technical indicators
Product Benefits
01Excellent scratch resistance
02Higher transparency
03 Lower specific surface area and oil absorption have little effect on coating viscosity
Application of wood coating
In wood coatings, it is suitable for thin coatings and coating systems using small particle size pigments to promote surface smoothness and 85 degree gloss. SPHERILEX® DP-0110 is ideal for achieving satin and eggshell finishes that are resistant to polishing and scrubbing. When mixed with silica matting agents, deep matte, natural-looking wood coating effects can be achieved with improved scratch, buff and mar resistance.
Application of plastic paint
Plastic paints have a need for scratch resistance in some fields such as automotive interior paints and 3C coatings, especially matte black paints, which leave a mark after being scratched. Adding SPHERILEX ® DP-0110 can effectively improve the scratch resistance of the coating film. The recommended addition amount is 6-10%.
Application suggestions
01 Anti-settling
SPHERILEX ® DP-0110 has a relatively high specific gravity and needs to be prevented from settling. It can be used with Evonik's easily dispersible gas silica AEROSIL ® E972 to prevent settling.
02 Matting efficiency and transparency
Matting agent has a negative effect on scratch resistance. The more it is added, the worse the scratch resistance. To improve the matte scratch resistance, the amount of matting agent used needs to be reduced. Evonik's ACEMATT ® TS 100, ACEMATT ® 3300, and ACEMATT ® 3400 gas phase type matting agents have high matting efficiency and transparency, achieving the required gloss while reducing the amount of matting agent used.
