VK-T02 is a white free flowing powder. Nano tio2 particle size is only 10-50 nm, is a screen ultraviolet radiation function and produce color effect of a kind of transparent material. Because of its transparency and anti-ultraviolet function and unification of makes it once was published, and prevent bask in skin care in, plastic film products, wood protection, transparent durable surface paint, fine ceramics and other aspects have gained wide application.
Nano tio2 (VK-T02) of strong ultraviolet ability is due to its high refractive index sex and highlights activity. Its anti-ultraviolet ability and its mechanism and its size relevant: when the particle size is bigger, cut off to ultraviolet reflex, scattering is the main and medium wave area and long wave area of ultraviolet are valid. The mechanism is prevented bask in simple cover, belong to the general physical bask in, prevent bask in ability is weak; With the decrease of the size, light can through nano-silicon dioxide (VK-T02) particle surface, to long wave area ultraviolet reflex, scattering sex is not obvious, and the absorption of medium wave area of ultraviolet obviously increased.
Property:
Effective resistance to UV.
Easily dispersed in water based and solvent based systems.
Non Toxic Uniform Particle Size:
1.Cosmetics and Sunscreen – provides highly efficient resistance to UV and reflection of visible and infrared light.
2.Plastics and functional fibres – improves resistance to aging, surface finish, weather resistance and brightness. Improves color and surface luster.
3.Coatings, Paint and Printing Inks - greatly improves aging resistance and scrub resistance. Improves self-cleaning properties. Paper making - used in paper coating to improve printability and opacity. VK-T02 is also used in metallurgy and aerospace industry.
