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. Quick Resin Selection Guide Ink typeCommon resin choicesMain advantage...
Choosing a water-based resin should begin with the application, not with viscosity, solids content, or price. Products with similar technical data can behave very differently in production. A resin may work well on paper but show weak adhesion on plastic film. A coating may form properly under heated drying but remain tacky at room temperature. A low-viscosity polyurethane dispersion may look too ...
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...
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...
Does Your Textile Printing Paste Still Feel Sticky or Crack? This Water-Based PU Resin Combines Softness with High Elongation Manufacturers of textile prints and thick coatings for footwear materials may have encountered these frustrating problems: The printed paste remains sticky after drying and causes blocking when the fabrics are stacked. The coating cracks or peels after several washes. In co...
The softness or stiffness of a textile resin film affects fabric feel, blocking resistance, and the ability of a print layer to withstand rubbing and deformation. A film that is too soft or too hard for its application may affect the finished textile during processing, storage, and use. “Too soft” and “too hard” depend on the intended application. Prints on soft clothing fabrics and backcoatings t...
The wall feels dry, but after a light shower, visible streaks appear. Some areas may also look glossier than the surrounding surface. Does this mean the acrylic emulsion has poor water resistance, or could the additive package be contributing to the problem For exterior paint formulators, the starting point is to examine the formulation and drying conditions together. Why a Dry Surface May Still B...

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...
