Altowhite UF is a calcined aluminum silicate engineered to provide improved optical properties in paint systems when compared with conventional calcined kaolins as a pigment extender.
Altowhite UF pigment extender is chemically stable over a wide pH range and easily disperses in all systems.
Calcined, fractionated kaolin with extremely low grit and controlled particle size.
Pigment spacer and gloss control in paint.
