Requirements of powder coating for rutile titanium dioxide

Faced with the development of powder coatings, titanium dioxide manufacturers all over the world have been exploring the varieties of titanium dioxide used for a long time After full study, it is not necessary to develop a special type of titanium dioxide for powder coating All kinds of titanium dioxide can be used by powder coating formulation designers No anatase titanium white powder coating is used in developed areas abroad The rutile titanium dioxide used for powder coating should have: excellent opacity, high weather resistance (external use) and optical rotation resistance (internal use, external use), high achromatic power, high luster, low light fog, best fluidity, good uniformity in coating, suitable gelation time, etc In addition, to ensure the corner coverage of the base material and the non pinhole property of the coating film are also the requirements of titanium white for powder coating The rapid development of thin film powder coating and matte powder coating abroad has put forward some specific requirements for titanium white DuPont R-900, r-902, r-960, r-960vhg, r-702, r-700, r-960 and r-103 for plastics can be conditionally used in powder coatings In addition, according to Kronos recommendation, 205921602310 and 2330, they are also titanium white for powder coatings In order to reduce the cost, 2190 with high brightness, high relative scattering force, high gloss and better durability can be used instead of 2057 with low relative scattering force and good durability, so the amount of titanium dioxide in powder coating can be reduced The cost of powder coating can be reduced by 7% while the coating performance remains unchanged.
