OnColor™ FX™ Special Effect Colorants PRODUCT BULLETIN Special effects can help boost the visual appeal of plastic products and parts in many applications. The OnColor™ FX™ Special Effect Colorants portfolio includes a myriad of effects including metallics (e.g., silver, copper), natural look (e.g., wood grain, granite, speckles), gloss and brilliance (e.g., pearlescence, iridescence, frost), high-visibility (e.g., fluorescence, sparkles) and color-changing (e.g., photochromic, thermochromic). In addition, OnColor special effects are incorporated into the plastic during part manufacturing, removing the need for secondary processes like painting, eliminating the associated VOC emissions and preventing peel-off issues.
