 Hiding Power is applied when the pigment surface, cover the surface background capability. Hiding can be expressed numerically, which is equal to the background is completely covered when the unit surface area (for example lm2) needed to paint in grams. For example, titanium dioxide hiding power, such as in terms of thousands of dry pigment, compared with 45- ~ 509 / m2; zinc white for the 1009 / m2; lithopones to 1209 / m2; lead white is 1379 / m2 and the like. Therefore, the same as a white pigment, titanium dioxide hiding among the best. The following content is provided by Lu Yan Xiao Bian, thank you for your support!
Hiding power also, and the following factors.
1,3) pigment particle size in general, the greater the hiding pigment particles smaller, but too small pigment particles, such as when less than the wavelength of light, the light is no longer reflected by the pigment particles, it hiding fall. When the pigment particles are generally 0.5 / zm hiding for the best.
2, paint pigment molecular structure of crystalline polymorph of hiding the lower symmetry higher than the low symmetry; pigment crystal flaky hiding larger than the rod; pigment high crystallinity lower than crystallinity.
3, light absorption characteristics of the pigment itself is generally light-absorbing ability of the pigment, hiding is relatively large, such as carbon black, can absorb almost all of the incident light, so it is a great hiding pigments. Shenzhen masterbatch
4, the difference between the refractive index of the pigment and the colored resin in general, the refractive index of the refractive index of the pigment and resin crystals larger difference, then paint the greater the opacity resin
