Coil coating

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
