JS-280C product feature:
1.High extinction efficiency (use of advanced production technology to make the gap matting agent , 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)
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.)
