Requirements of powder coatings for rutile titanium dioxide

in the face of the growing development of powder coatings, titanium white varieties have long been discussedAfter full research, it is not necessary to develop a special type of titanium white for powder coatings, all types of titanium whites are available for powder coating formulation designers to chooseDeveloped areas abroad do not use sharp titanium-type titanium white preparation powder coatingpowder coating with gold-redstone titanium white should have: excellent opacity, high weather resistance (external use) and spin-resistant light (internal, external), high color dissipation, high gloss, low light fog, optimal fluidity, in the coating has good uniformity, suitable glue time and so onIn addition, to ensure the substrate angle coverage, coating film without pinhole, etc, is also the powder coating with titanium white requirementsThe rapid development of film powder coatings and lightless powder coatings abroad have put forward some specific requirements for titanium whitesDuPontR-900, R-902, R-960, R-960VHG, R-702, R-700, R-960 and plastic varieties R-103 can be used in powder coatings, according to Kronos, recommended by Kronos, 2059, 2160, 2310 and other brands, also white powder savesIn order to reduce costs, with a high degree of lightness, high relative scattering force, high gloss, better durability of 2190, instead of relative scattering force is low, good durability of 2057, the amount of titanium white in powder coating can be reducedInstead of cheap physical pigments such as calcium carbonate, the cost of powder coatings can be reduced by 7%, while the coating performance remains the same
