Inorganic pigments andhybrid pigmentsSicopal ® / Sicotan ® / Sicotrans ® / Paliotan ®Sicopal ® Yellow pigmentsInorganic pigments continue to form the basis for practically allcoil coatings. They are stable at high temperatures and largelyresistant to chemical and physical effects. In addition, they havehigh hiding power, good rheological properties and excellentfastness to weathering.A selection of pigments from our range for plastics coloration isalso illustrated below. Final inspection tests on these pigments,unlike those on pigments for coatings, are carried out on apolymer. Therefore, the possibility of variations in coloristicproperties and color strength when they are used in coil coatingsystems cannot be ruled out.The greenish Sicopal ® Yellow L 1100 and L 1120 and the reddishSicopal ® Yellow L 1600 are standard pigments for producingbrilliant yellow, orange and red shades. Mixing them withPaliotol ® or Paliogen ® pigments yields weather-fast shadeswith good hiding power that are much more brilliant thancombinations with other lead-free inorganic pigments.The resistance to SO 2 of the Sicopal ® Yellow grades is comparableto that of highly stabilized Sicomin ® (lead chromate) grades.In a maritime climate, these pigments may react chemicallywith the binder components of PVC plastisols and PVDF systemsto cause a dark discoloration. This effect has not been observedin other binders.
Sicopal ® Blue and Green pigmentsSicotrans ® pigmentsThese complex inorganic oxide pigments with a spinel structureare characterized by excellent heat resistance and fastness toweathering. Unlike Heliogen ® Blue pigments, Sicopal ® Bluepigments (cobalt blue) absorb the UV component of sunlight onlyto a limited extent. If coatings are pigmented with cobalt bluealone, there is a risk of chalking, with subsequent loss ofadhesion and peeling. This can be avoided by combining thecobalt blue with UV-absorbing pigments such as titanium dioxide.Sicotan ® pigmentsSicotan ® pigments are colored complex pigments based ontitanium dioxide with a rutile structure. A wide range of vividshades with good hiding power can be produced by combiningthem with organic yellow and red pigments. Their resistanceto weathering and heat is outstanding.Sicotrans ® pigments are ideal for coil coating systems asfunctional pigments. They absorb UV light and thereby protectthe film from damage. In addition, they offer styling possibilitiesfor special-effect coatings because they are transparent. Theresistance of Sicotrans ® Yellow L 1916 to heat is limited, withchanges in shade occurring at the baking temperatures normallyused for coil coating.Paliotan ® Yellow and Red pigmentsPaliotan ® Yellow and Red pigments are hybrid pigments based onorganic and inorganic pigments. They economically combinestrong hiding power with high chroma. They also have excellentresistance to weathering and are environmentally friendly.04 05
