Description:

?

1.? Liangjiang Brand-Rutile titanium dioxide R909 for coating is rutile titanium dioxide pigment manufactured by the sulphate process with excellent control of particle-size and unique coating technology. It is coated with inorganic and special organic surface treatment. It has excellent pigment properties, with good whiteness and gloss, excellent hiding power, strong tinting strength, superior weatherability and chalk resistance, is easy wetting and easy to disperse. R909 can endow the coating film bright color, enhance its mechanical strength & adhesion and keep it from crazing. It can also prevent the penetration of UV or moisture, improving the chalk resistance of film to extend its working life.

?

Application fields:?

?

R909 is rutile titanium dioxide pigment special for coating. It can be used in a wide range of architectural coatings, water soluble coatings, industrial coatings, powder coatings, special paint for ships, coil coatings, anti-corrosive paint, antifouling paint etc.

Rutile titanium dioxide for coatings

?

This substance is of high importance for coatings.
Based on experiments and expert knowledge, we produced rutile pigments in various grades. Each grade leads to excellent performance properties for the type of paint or coating being manufactured like high chalk resistance with extreme durability for exterior paints and coatings, or low abrasion and high opacity in inks.
Using these TiO2 pigments, coatings resistant against weathering. They can be applied in external uses and have water proofing properties.
Low abrasion of this form of pigment is important in producing flexographic inks. Also, because of resistance against weathering it increases the life of glasses and is useful for polishing. TiO2 pigments are used in industrial and architecture coatings because of their naturalness, whiteness and opacity.
Applications of TiO2 rutile pigments are as follows:
??Industrial Coatings
? Powder Coatings
? Silicone Coatings
? Mineral Plasters
? Can Coatings
? Decorative Coatings
? Wood Protecting
? UV Coatings
? Automobile Coatings
? Low-VOC Systems

Coatings industry consumes most qty of titanium dioxide, especially the rutile type. The global coating industries occupy 58% - 60%, mainly because the aspects of the performance is much better than the other white pigments. So the coating using by titanium dioxide is much higher than ordinary filler, because titanium dioxide is an integral part of in the coating, covering and adornment, its role is not only more important is to improve the physical and chemical properties of paint, bust also to improve the mechanical strength of the coating, adhesion, anticorrosive, light and weather resistance.So during of the production of coatings, It’s reasonable for us to choose the suitable type and specs!
