1, high extinction efficiency (use of advanced production technology to make the gap matting agent of 1.8ml / g, can be very high extinction efficiency)
2, added easily (can be added at any stage of the production process)
3, the film transparency is good (high purity matting agent, few impurities, its refractive index 1.46, and therefractive index of the resin is similar, so that the film transparency is good.)
4, excellent suspension characteristics (due to generation of a matting agent after a unique organictreatment, and they have good suspension, even after prolonged storage and will not form a hardprecipitate.
5, good dispersion (easily dispersed in any paint, just use normal-speed blender, about 15-20 minutes aftermixing can achieve good dispersion, fineness values up to 15-25 microns.)
(Advisable without sanding or three-roll mill for a long time to be dispersed, so as not to reducethe effect of extinction, and the viscosity increases. Because this product is added to the wax
Surface treatment products). This product does not require polishing, easily dispersed, can be directly added to the coating, the dispersion using a high speed mixer for 10-20 minutes, the dispersion speed of about 1200 rev / min (peripheral speed of the blade 5 m / sec.) The finenessis less than 2.5um . matting effect, with anti-sink effect.
1, high-end furniture, paint, oil-based ink type A; B-type water-based inks.
2, general industrial coatings
3, decorative paints and coatings marketed
4, thin film coatings, such as leather; decorative sheet

Semi-matte: 3-6% of the whole dumb: 6-10%
Matting agents due to large pore volume, and therefore hygroscopic, need to re-sealed after use,and run out as soon as possible
