Throughout the UV region (200 to 400nm), the absorption capacity of the zinc oxide to light is stronger than the titanium oxide. Of zinc oxide effective role for a long time, long the band of ultraviolet shielding ultraviolet A (UVA, wavelength 320 ~ 400nm) and ultraviolet B (UVB, wavelength 280 ~ 320nm) were shielding effect, through the visible, the high chemical stability and thermal stability.
Nano-zinc oxide have good hydrophilic and lipophilic effect well dispersed in the latex paint, and enhance the ability of latex paint UV-and nano-zinc oxide transparency can improve latex paint hiding. Weakening the sensitivity of the latex paint to humid environmental conditions, to improve the resistance to aging.
Conjunction with nano-titanium dioxide (VK-T25) for interior and exterior wall emulsion paint can has shielded UV coating absorb infrared and antibacterial mildew role, also has a thickening effect, so that the pigment dispersion stability. NanoZinc oxide for ship paint raw material, can not only play the role of ultraviolet radiation shielding, and can kill a variety of microorganisms, thereby increasing the speed of navigation and extend the maintenance period.
