Resin is the main film-forming component in printing ink. It influences pigment dispersion, adhesion, drying speed, gloss, flexibility and resistance. There is no universal resin for every ink. The right choice depends on the ink system, substrate, printing method and the conditions the printed product will face after printing.

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...

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...

Why PTFE Coatings Release Food but Adhere to Metal: The Role of Primer Resins
- 2026-10-30 11:18:53
- admin
A fried egg slides easily off a non-stick pan, yet the coating underneath remains attached to the metal through repeated heating and cooking. This raises an interesting question: if PTFE is known for its exceptionally low adhesion, how can it form part of a durable coating on cookware? The explanation lies in the difference between the surface that contacts food and the interface that bonds with t...
