Other name: Pigment brown 33
Chemical properties: Zinc/iron/chromium oxide (Zn-Fe-Cr-O)
Pigment index number: Pigment Brown 33/P Br 33(77503)
CAS number: 68186-88-9
Appearance: Dark brown powder
Compound inorganic pigment zinc iron chromium brown is calcined by high temperature. The result is a unique chemical structure. This pigment has good shading against ultraviolet and visible light, excellent heat resistance, chemical inertness and UV stability. No coloration or migration. It has excellent durability and covering power and is commonly used in applications requiring heat, light and weathering resistance. It is compatible with most resin systems and polymers and is warp-free. Typical applications include liquid and powder coatings, printing inks, plastics, building materials, and other similar applications.
Suitable for all indoor and outdoor uses;
It is recommended to combine with high performance organic pigments in opaque formulation for better weather resistance.
Recommended for applications with high chemical and weather resistance;
Because of its very low free iron content, suitable for PVC polymer system;
Suitable for colouring systems that require total solar reflectance (T.S.R);
Suitable for PVC-P; PVC-U; PUR; LD-PE; HD-PE; PP; PS; SB; SAN; ABS/ASA; PMMA; PC; PA; PETP; CA/CAB; UP and other polymers; Color master; Engineering plastics; Wood plastic; Powder coating; Water-based coating; Solvent-based coating; High temperature baking coating; Fluorocarbon coatings; Coil coating; Automobile coating; Camouflage paint; Printing ink; Building materials; Cement; Mortar; Concrete; The roof; Sintered sand.
