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...

How Do You Select the Right Tg for a Water-Based Acrylic Label Adhesive
- 2026-07-22 18:56:18
- admin
When formulating a water-based acrylic pressure-sensitive adhesive for labels, Tg is usually one of the first parameters we set. It indicates whether the dry adhesive film will behave relatively soft or firm at a given temperature and influences initial tack, peel adhesion, holding power, low-temperature performance and adhesive ooze. However, Tg alone does not determine whether an adhesive is sui...

What Is the Best Adhesion Promoter for UV Inks

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...
