Adjusting a water-based acrylic resin formulation is rarely as simple as adding one new material. For example, increasing resin hardness may make the coating film more brittle. Reducing the glass transition temperature can improve low-temperature film formation, but it may also reduce heat resistance and blocking resistance. Increasing the amount of hydrophilic groups may improve emulsion stabilit...

When UV ink comes off during a tape test, the primer is often blamed first. However, poor adhesion can also result from the film surface, contamination, incomplete primer drying or incorrect UV curing. Here, “adhesion promoter” refers to a primer applied before printing. No single grade is suitable for every plastic film. Choose the Primer by Substrate PET and BOPET films often benefit from a prim...
