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...

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...

Polyurethane (PU) can transform into a strong adhesive, firmly bonding tiles to walls; it can also become plastic parts like phone cases and keyboard keycaps; and even become shoe soles and sealing strips, exhibiting elasticity comparable to rubber. Why can the same material freely switch between the seemingly unrelated fields of "adhesive, plastic, and rubber"? Today, we'll uncover the secret of ...

Definition: Waterborne polyurethane is a new type of polyurethane system that uses water instead of organic solvents as a dispersion medium. It is also known as water-dispersible polyurethane, water-based polyurethane, or aqueous polyurethane. Characteristics Classification 1 By particle size and appearance 1. Polyurethane aqueous solution (transparent appearance, particle size <0.001 micromete...

Analysis of the Waterproofing Principle and Performance Advantages of Water-Based Polyurethane Fabric Coating Agents
- 2025-12-27 17:08:00
- admin
Water-based polyurethane fabric coating agents can impart a soft and full hand feel and leather-like texture to fabrics, and significantly improve the wrinkle resistance, shrinkage resistance, elasticity, and flexibility of the coated fabrics. Among them, water-based polyurethane coating agents with waterproofing properties are particularly popular with fabric manufacturers and consumers. So, how ...
