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
- 2026-08-01 10:23:15

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...

How to Choose a Waterborne Polyurethane Dispersion for Industrial Glove Coatings
- 2026-08-11 18:51:37
- admin
As global environmental regulations such as EU REACH and OEKO-TEX® Standard 100 become increasingly stringent, traditional solvent-based PU systems face growing restrictions in protective glove manufacturing. With advantages such as low VOC emissions and no DMFa residue, waterborne polyurethane (WPU) emulsions are rapidly becoming a key choice for glove manufacturers transitioning from solvent...

How to Choose a Water-Borne Adhesive for Hot Stamping Foil
- 2026-08-21 17:00:20
- admin
A good hot stamping result depends on more than the foil it self. The adhesive layer affects transfer quality, edge definition, adhesion, drying, and storage stability. When selecting a water-borne adhesive for hot stamping foil production, start with three points: the substrate, the coating process, and the stamping temperature. Check the Substrate Hot stamping foil may be used on paper, OPP, PET...

How to Reduce Pinholes in PTFE Coatings with PFA 001 Dispersion
- 2026-09-03 15:43:32
- admin
Poor surface smoothness, low gloss, and microscopic pinholes may occur during the spraying and baking of waterborne PTFE non-stick coatings. These defects can allow steam, fats, and corrosive substances to penetrate the coating over time, increasing the risk of blistering, peeling, and reduced non-stick performance. Why Pinholes May Form Pure PTFE has extremely high melt viscosity and limited flow...
