OnColor™ Naturals Colorants PRODUCT DESCRIPTION OnColor™ Naturals is a range of colorants formulated with natural pigments derived from plants, flowers, roots and minerals. A sophisticated mix of both pigments help deliver natural aesthetics from opaque to transparent and with a strong natural statement. Processing conditions can cause material properties to shift from the values stated in the information.

OnColor™ RC Environmental Black Color Concentrate OnColor™ RC Environmental Black color concentrate is derived from end-of-life tires, making it sustainable alternative to concentrates using virgin carbon black. It prevents tires from entering the waste stream and extends the useful life of the petroleum- based raw materials found in waste tires. Processing conditions can cause material properties to shift from the values stated in the information.

OnColor™ REC Polymer Colorants OnColor™ REC Polymer Colorants are derived from recycled content, making them a sustainable alternative to concentrates using virgin carbon black. Some of the information arises from laboratory work with small-scale equipment which may not provide a reliable indication of performance or properties obtained or obtainable on larger-scale equipment. Processing conditions can cause material properties to shift from the values stated in the information.
