  • HOW TO CALCULATE THE VOC CONTENT OF A MIXED

    The VOC of Mixture is a number that accounts for the following in a mixed coating: - The VOC content of each component in the coating - The amount of each component in the coating It is essentially a weighted average for the entire coating. If one component in the mixture has a higher VOC content, or is added in a higher quantity than the others,File Size: 593KB
