Smartbatch™ FX for Paint Replacement The replacement of paint on plastic parts with molded-in color (MIC) has several benefits. With MIC the incorporation of color with a color concentrate during the manufacturing of plastic components reduces the number of processing steps and complexity. Since the color is incorporated into the plastic matrix, it also prevents color peel-off and flaking.
