Pigments, color process for ready-mix concrete
With the Standley Color Batch system, ready-mix companies can incorporate Bayferrox C granulated pigments into a dry-to-wet mixing process to obtain all the advantages of liquid colors, but at a lower cost per yard. The process makes liquid colors on a single-batch basis using the producer’s own water. It uses granular pigments and separately weighs each of four primary colors. Pigment and water are mixed within seconds, and the liquefied pigment is transferred to the mixer. Flushing with water after each batch eliminates color contamination. Lanxess Corp.
