We Synox have 6 series of the iron oxide pigments. 1.SYNOX series?such as Red 4110,Red4130,Black 4330,Black4401 ,Yellow 4920(fast moving items) 2.INFINITY series,such as Red 5110,Red 5130 and so on 3.SYNOFIN ?MICRONIZED series??Synofin Red 110, Synofin Red 130M,and so on 4.HEAT RESISTANCE series?Black 4330T,Yellow 4313T and so on 5.Low Heavy Metal series;Red7110, Yellow 7313,Black7330 and so on 6.Ceramic series;Red 6189,Red6188,Yellow6488,orange6388 and so on Synox iron oxide pigments are selected from inert materials which are nontoxic, highly resistant to light, heat, alkali and lime. Synox grades covers micronized, granular, infinity and heat-resistant series to meet requirements from different fields. Keep color consistency and control quality strictly is our principle.
