DuPontTMTi-SelectTM TS-6200 formula guide 

 Product Description 

 DuPontTM Ti-SelectTM TS-6200 titanium dioxide for coil coatings, automotive coatings, powder coatings, architectural coatings and industrial coatings outdoor super durability paint and other applications. This grade offers excellent dispersion and superior protection light resistance. 

 Points Formula 

 Coating production typically requires two steps: grinding against the thin and in one or more grinding operation, the solid ingredients (including titanium dioxide pigments, other pigments and fillers) dispersed paint solvent and dispersant mixture. Get high solid After the content of abrasive slurry, and then the solvent, a mixture of resins and additives deployment (diluted). to obtain the desired composition and consistency of the paint product, the following table lists the abrasive and water-based and solvent-based paint in the standard deployment components. 

 In the high-grinding process, energy must be effectively delivered to the titanium dioxide aggregates, so that the paint particles in the dispersion stability of the state. Abrasive grinding process, the quality and speed to some extent by the use of titanium dioxide Pigment grade decision, there are several brands to choose for coatings formulators, grinding conditions should be optimized based on selected brands.

 Ti-SelectTMTS-6200 dispersant requirements 

 Ti-SelectTMTS-6200's unique surface designed for optimum dispersion and design, which is reflected in its low requirements on the dispersant. 

 And other super weatherability compared to titanium dioxide pigment, TS-6200 requires less dispersant, especially in water-based formulations. 

 Figure compares the TS-6200, key competitors and super-patience grade Ti-Ture R-960 dispersion, R-960 ultra long-term weathering recognized standard titanium dioxide pigment. 

 Water-based formula recommended 

 Use the right amount of dispersing agent to guarantee the desired coating performance is critical, first step in a successful formula is to determine the TS-6200 dispersant requirements. Dispersant type and dispersant according to requirements specified uses vary. Control pigments and the ratio of dispersing agent can not only ensure good dispersion, but also can enhance the life of the paint film quality and performance. 

 Appropriate viscosity for quick and thorough abrasive dispersed pigment is critical, if the viscosity is too low abrasive, abrasive grinding in the transmission of energy in the will is not sufficient; However, if the viscosity is too high, will lead to ground materials and grinding equipment overheating. TS-6200's viscosity is generally lower than other super-abrasive durability titanium dioxide pigment, so we recommend that, in the ultra-durability inherent in the commonly used titanium dioxide content, based on the solid titanium dioxide abrasive content of 3-5%. 

 Solvent formulation advice 

 With water-based coatings, abrasive formula correct formula for success is critical solvent-based paint order confiscation of the use of TS-6200 compared to other ultra-durability paint ease of processing advantages, abrasive surface must be unique TS-6200 chemical nature of the formula. 

 We recommend: 

 l increase the pigment and binder (P / B) ratio, it is higher than other super-weathering the general level of titanium dioxide pigment for long oil alkyd resin, recommended ratio of not less than 6. 

 l Adjust the amount to get enough solid viscosity, thereby enhancing the grinding efficiency in most of the long oil alkyd resin, the optimum range of 85-87%, of course, is ultimately determined by the resin. 

 l speed range 16-20 m / sec The speed is sufficient to form a slurry in grinding a good cut. 

 l using Disperbyk-110 or dispersing agents such as soy lecithin.
