Application Data

Michem® Flex Barrier 5780 is designed to be applied onto AlOx coatings produced on Bobst supplied vacuum platforms on BOPET substrates. A thin, dried coating is transparent, contributes to AlOx protection and allows further processing of BOPET/AlOX film. 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 should be diluted to 15-20% solids with soft water and dried thoroughly after application. If needed to adjust coat weight and processability, it is possible to dilute further with soft water.

Storage

Handle in accordance with good industrial hygiene and safety practice.
