Application Data

Michem® Flex B3511 is designed to be applied onto metalized film or used as a metal adhesion primer. A thin, dried coating is transparent, contributes to metal protection / adhesion and allows further processing of metalized films. Properly coated and dried films are not expected to exhibit blocking to the backside. Suggested coat weight is 0.4 – 0.8 dry gsm. It is recommended that the product be used undiluted, however if needed to achieve target coat weight, it can be diluted slightly with soft water.
