Titanium is a well-known metallic element that is used in many industrial applications Pure titanium dioxide (TiO2) is basically a fine white powder that provides a white pigment that is incredibly useful in all applications.
TiO2 has been used for years as an additive in a variety of industrial products, including paints & coatings and PVC.
Titanium Dioxide for PVC
The plastic industry is one of the major users of TiO2 thanks to its features including high hiding power and pigment characteristics that help enhance its use in plastics. It increases heat resistance, weather resistance, and light resistance of PVC products, while also providing protection from UV rays.
Titanium dioxide is also used in many thermoplastic and thermosetting plastics, including polystyrene, polyolefins, and polyvinyl chloride. It can be used in several ways such as mixing with a solution containing a plasticizer, dry resin powder, or it can be processed into a colour masterbatch before processing and shaping.
Titanium Dioxide for Paints and Coatings
Like in PVC, titanium dioxide is the ideal white pigment to help you obtain intense whiteness and covering power in paints and coatings. This is because of its high refractive index and the ability to be transparent to visible light. What makes titanium dioxide even more attractive is its spherical shape, particles of the right size, and provides a range of post-treatment options.
In paints and coatings, titanium dioxide provides opacity and brightness while also enhancing the durability of exterior paints. However, its effectiveness as an opacifier or brightener is significantly impacted by the paint-making process and the formulation specifications.
TiO2 produces clean, brilliant tints, imparts neutral tone and maximum brightness in white coatings. It is also incredibly cost effective and disperses easily and satisfies the requirements of modern production procedures, producing high-gloss, low-haze coatings.
Notably it works well with all water-borne, oil, and solvent paints & coatings for exterior use.
