Application Data

Michem® Flex B3510 is designed to be applied to polymer materials using gravure or flexographic coating processes. Suggested coat weight is 0.3 dry gsm. At the recommended coating weight, the dried coating is transparent, non-blocking and contributes to oxygen barrier properties of polymer materials. It should be used undiluted and dried thoroughly after application.


Avoid breathing vapors or mists. Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Use personal protective equipment as required.
