How Waterborne Polymers Improve Flexographic Printing Quality
- 2026-05-07 14:50:35

In flexographic printing, the performance of waterborne polymers and resin systems directly affects ink stability, color consistency, adhesion, and production efficiency. Traditional water-based inks may cause anilox roller clogging during long production runs, leading to unstable ink transfer and interrupted printing. In comparison, UV flexographic inks cure instantly under UV light, helping redu...

Why Are Some Waterborne Polyurethane Dispersions Milky White While Others Are Translucent
- 2026-07-16 15:53:46
- admin
Waterborne polyurethane dispersions, commonly known as PUDs, may appear milky white, translucent, or slightly bluish in the liquid state. This difference is mainly related to particle size, particle size distribution, and how strongly the dispersed particles scatter visible light. In general, milky dispersions scatter more light, while finer dispersions allow more light to pass through. However, a...

How to Choose the Right Water-Based Resin for Your Application
- 2026-08-05 17:59:28
- admin
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 ...
