V - 991 is using nanometer phase hybrid technology, make the distribution of polymer nanoparticles,

in the process of synthesis in the process of film coating the surface concave and convex effect, so

that the light source of a diffuse physical extinction method, replacing the traditional extinction powder

technology, this way of extinction can reach 20 ° to 60 °, 85 ° full extinction Angle, effect is more soft,

does not affect the light transmittance.
