Curry N500 GS is a unique spray-dried, primary yellow natural iron oxide pigment. It can be used alone, in contrast to synthetic yellow which must be blended with other colors to be useful in Portland cement applications. In addition, blending small amounts of synthetic red, yellow or black can expand the color options into desirable natural earth tones. Curry N500 GS is lightfast, insoluble in water and non-reactive with solvents, oils and most resins. Curry N500 GS is a pigment that will redefine how colored concrete is produced while also lowering production costs.
