OnColor™ SC Super Concentrate Technologies Optimize Color Usage and Expand Sustainability PRODUCT DESCRIPTION OnColor™ SC Super Concentrate color technologies feature substantially greater active pigment loadings than traditionally designed color masterbatches. These technologies enable lower colorant use rates while achieving the same quality as higher let down ratios and traditional masterbatches. Increase Sustainability Using More Recycled Content OnColor SC Super Concentrates give you the flexibility to incorporate higher levels of post- consumer regrind (PCR) than with traditional color masterbatches to help meet sustainability initiatives and recycled content requirements without adversely affecting the performance or aesthetic of your designs.

Super concentrates can give greater flexibility in coloring higher levels of PCR than traditional masterbatches, and can be used in a multi- layer bottle construction Additives can provide thermal stability by improving physical properties and neutralizing variability.
