Application Data

Michem® Flex B3510I 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 undiluted and dried thoroughly after application. A black light can be used to see the coating during application to confirm uniformity of the coating onto the substrate.


Handle in accordance with good industrial hygiene and safety practice. Use personal protective equipment as required.
