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.

As mentioned earlier, fluoropolymers can be used in many different areas, and the optimal fluoropolymer type and appropriate color masterbatch will depend on the part’s requirements. Understanding the part size and wall thickness allows a masterbatch to be designed with the appropriate pigment strength, particle size, and dispersibility. Color masterbatch formulations can produce opaque colors or can be developed with the appropriate pigment particle size and loading to enable translucent colors.
