DuPonttm Ti-Pure R-105 titanium dioxide 

 Product Description 

 DuPont Ti-Pure R-105 is a chloride for preparation of rutile titanium dioxide pigment. Rutile titanium dioxide white pigment is the most widely used. R-105 combines the neutral white hue and opacity characteristics moderate make color matching easier, the user is outside a specially designed plastic titanium dioxide. silica coating technology to minimize the TiO2 surface and plastic products in the interaction of other substances. R105 along with organic surface treatment to guide the powder with excellent flow and processing, while reducing the inorganic coating of titanium dioxide that is only shared by moisture absorption. R-105 is a fine, dry powder, has the following basic properties:

 Use recommended 

 DuPont Ti-Pure R-105 is recommended for outdoor use in plastics, especially PVC profiles. R105 silica coating technology used, minimizing the TiO2 surface interaction with the surrounding environment, which can reduce the general outdoor plastics in common "powder", cracking and other surface degradation. R-105 surface treatment also makes liquid and dry powder dispersion in plastics technology to achieve the best. 

 Basic properties of Table II 




 Better coverage 

 Neutral white hue 

 Excellent weather resistance 

 In the following material in the dispersion: 

 Excellent dry-mixing process 

 Well plasticized PVC resin 

 Good melt blending operations 


 R-105 optical properties of PVC products for outdoor use are particularly useful. R105 an excellent combination of brightness, a neutral white background and moderate color strength. 

 R-105 weather 

 Ti-Pure R-105 to have the effect of SiO2 coated weather-resistant technology is optimized to make it even completely coated the surface of TiO2, SiO2 film as a layer mask to block the TiO2 surface with polymers or other additives between the reaction of this type of product in the topical application is particularly important because of the TiO2 particles absorb ultraviolet light energy may cause the polymer catalytic reaction. R-105 outdoor plastic products can provide excellent gloss retention.

 R-105 anti-fading 

 R-105 used in surface coating technology to provide excellent anti-(due to photochemical walls) fading. 

 R-105 system can lead gray PVC system to minimize problems, but also make the system phenol polyethylene yellow lines to minimize problems. 

 Easy transfer of 

 R-105 during the bulk of the special surface treatment to improve the delivery of much of this organic and inorganic composite coating surface treatment to optimize liquidity.
