Through its Division Hoover Color the CATHAY Group offers transparent iron oxides obtained through a unique process, recovered from abandoned mine drainage through a waste elimination process that results in clean water. They can color a wide range of products including paints and coatings, plastics, paper, mulch and more. Contrary to synthetic transparent iron oxides, these EnvironOxide products show an outstanding dispersibility which reduces the dispersing process to the use of a high speed disperser.
