What are the advantages of using water-based polyurethane for fabric coating
- 2025-11-04 17:44:55
- admin
Fabric coating is a processing technology developed in textile finishing because it can give fabrics various functions, unique style, feel, and appearance, and increase product added value. Therefore, coated textile products are constantly emerging internationally, and their application fields are becoming increasingly wide. The low-temperature resistance, high elasticity, and high modulus of poly...

Steps for Coating Metal with Polyurethane Emulsion
- 2025-11-19 17:29:31
- admin
The process of coating metal with polyurethane emulsion can be divided into the following steps: Surface Preparation: Before applying the polyurethane emulsion, the metal surface needs to be properly prepared. This typically includes cleaning the surface, removing oil, dust, and other impurities, and performing rust removal to ensure coating adhesion and durability. Rust removal can be done mechan...

Basic Knowledge of Waterborne Coating Formulation - Part 1
- 2025-11-26 17:22:42
- admin
Waterborne coatings, including waterborne wood coatings, are coatings that use water as the dispersion medium and diluent. Unlike less commonly used solvent-based coatings, their formulation systems are much more complex. Formulation design requires attention not only to the type of polymer, the properties of the emulsion and dispersion, but also to the rational selection of various additives and ...

Basic Knowledge of Waterborne Coating Formulation - Part 2: Waterborne Resins
- 2025-11-28 17:25:32
- admin
In water based paint formulations, the base material is the key component that forms the paint film and determines its performance. When designing the formulation, the amount of waterborne resin should be maximized, accounting for 60-70% by volume, to ensure the highest possible content of effective film-forming agents in the paint. This guarantees a thicker, fuller paint film in a single coat. Wa...

Film-Forming Aids Polymers that make up emulsions or dispersions typically have glass transition temperatures above room temperature. To ensure good integration of emulsion particles into a uniform paint film, film-forming aids must be used to lower the minimum film-forming temperature (MFFT). Film-forming aids are a class of small-molecule organic compounds that eventually escape and volatilize f...
