Synthetic Red Iron Oxides from Cathay Industries are high-quality inorganic pigments suitable for wide range of demanding colorant applications. Typical applications include architectural paints, industrial coatings, product finishes, wood stains, plastics, rubber, ceramics, inks, paper, concrete, stucco, cement and mortar.
The excellent dispersion characteristics and high tint strength of our Synthetic Red Iron Oxides make them particularly useful in many of today’s high performance coatings. These cost-effective pigments eliminate the need for more expensive dispersant additives and pre-dispersed liquid pigment concentrates.
RA11A is a bright and yellowish red powder pigment with high heat stability and excellent weathering and light fastness. It is produced with strict quality tolerances and reliable performance, which offer outstanding opacity, acid and alkali resistance, chemical resistance, exterior durability and compatibility.
As all CATHAYCOATTM “RA” grade Iron Oxide Red, RA11A is highly micronized to offer easy dispersion with high-speed impeller (Cowles type) milling equipment or single & twin screw extruders.
