The SACHTLEBEN white pigments landscapeBrightening powerand undertoneThe brightening power of TiO 2pigments can also be describedas the ability to lighten the original color of plastics.TiO 2has a higher brightening power compared to all otherwhite pigments, as a result of its high refractive index. Its narrowparticle size distribution assures good hiding power, in additionto excellent brightening power and positive effects onundertone. In general, the smaller the particle size the bluer theundertone. Sachtleben supplies rutile pigment products forthe entire undertone range, extending from bluish (e.g. R 405),neutral or slightly bluish (e.g. R 420) to warm yellowish (e.g. R 320).All Sachtleben anatase pigments are even more bluish but offer aslightly lower brightening power along with the lower refractiveindex. Zinc sulfide white pigments are second in refractive indexcompared to titanium dioxide. While SACHTOLITH is a pure bluishspecialty, bluish color toned Lithopone, a co-precipitate of zincsulfide and barium sulfate, is used together with high quality rutilepigments, predominantly in the masterbatch application.SACHTLEBEN PIGMENTS LANDSCAPEREL.

White pigments – Rutiles for outdoor applicationsSACHTLEBEN R 420SACHTLEBEN R 420 is an alumina-silica-zirconia surface-treatedhydrophobic rutile titanium dioxide pigment and combines outstandingdurability with excellent optical properties. SACHTLEBEN R 420‘sfine crystallite and particle sizes position it in the group of neutral/blue-undertone plastics grades. SACHTLEBEN R 420 is highlysuited for use in nearly all polymers Thanks to its high level ofresistance to outdoor exposure, it is particularly popular foruse in products for outdoor service, including window-profiles,tubes, PVC and polyolefin films, etc.SACHTLEBEN RFK 3SACHTLEBEN RFK 3 is an alumina-silica-zirconia surface-treatedhydrophobic rutile titanium dioxide pigment, and combinesoutstanding durability with excellent optical properties. Its finecrystal and particle sizes position SACHTLEBEN RFK 3 in thefamily of blue-undertone plastics grades, especially for all kindsof outdoor application.SACHTLEBEN RD 3SACHTLEBEN RD 3 is an alumina-zirconia surface treated hydrophilicrutile titanium dioxide pigment and combines outstandingoutdoor durability with excellent optical properties, i.e., highbrightness and lightening power, opacity, excellent gloss andeasy dispersibility. SACHTLEBEN RD 3‘s crystal and particle sizesposition it in the group of neutral undertone plastic grades.SACHTLEBEN RD 3 is highly recommended for high-quality plastics,particularly those for exterior applications.SACHTLEBEN RKB 4SACHTLEBEN RKB 4 is a micronized rutile titanium dioxidepigment treated with alumina-silica-zirconia compounds.It combines excellent weather resistance with good opticalproperties. RKB 4 is especially designed for exterior applicationsbecause of its very high gloss retention and resistance.It is an excellent alternative in gel coats and plastic systemswhich are sensitiv regarding the organic treatment.Sachtleben R 420 sachtleben RFK 3 sachtleben rD 3 SACHTLEBEN RKB 4Titanium dioxide classification R2 R2 R2 R2Inorganic treatment(compounds based on:) AI, Si, Zr AI, Si, Zr AI, Zr AI, Si, ZrOrganic treatment Polysiloxane Polysiloxane Polyol PolyolTiO 2content [%] approx. 95 approx. 93 approx. 93 approx. 94Undertone neutral/bluish bluish neutral neutralWeathering stability excellent excellent very good excellentStability2025RFK 3R 420RD 3RKB 410098RFK 3R 420RD 3RKB 4CIE b*10CIE L*969459200 500 1000 1500 2000 25003000 3500900 500 1000 1500 2000 25003000 35005
