Application Data

Michem® Flex Barrier 3510 is designed to be applied to polyolefin 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 polyolefin materials. It should be used undiluted and dried thoroughly after application.
