Pigment Red Of Iron Oxide | ||
Iron Oxide pigment is used as dye or colorant in various prefabricated concrete parts and architectural products and materials. Blue iron oxide is directly added into cement to color up various indoor and outdoor cement surfaces, i.e. walls, terraces, ceilings, pillars, corridors, roads, car-park, stations, etc, as well as various building ceramic and glazed ceramics, i.e. facing bricks, floor tiles, roofing tiles, panels, terrazzo, mosaic tiles, artificial marbles, etc.
Application:
1).Constructions: asphalt and concrete, color floor tile, color facing bricks terrazzo, roofing tiles.
2).Paint and coating: water-based exterior and interior wall coating, oil paint primer and finish paints and anticorrosion paint.
3).Plastic and rubber: thermosetting plastic and thermoplastic and rubber track.
4).Others:paper,leather,ceramics,cosmetic and medicine
