【Introduction】 In industries such as coatings, adhesives, leather finishing, and textile processing, the terms "resin," "dispersion," and "emulsion" appear frequently, often confusing newcomers. As a manufacturer with many years of experience in the waterborne polyurethane field, we understand that understanding the differences between these fundamental concepts is crucial for material s...
Packaging and Printing Scenarios 1. Acrylic emulsion for paper packaging bonding: Strong adhesion, environmentally friendly and odorless. 2. Acrylic emulsion for color box printing: Good adhesion, vibrant colors that don't peel off. 3. Acrylic emulsion for corrugated paper bonding: Strong water resistance, cardboard boxes are resistant to pressure and don't easily fall apa...
The following are examples of acrylic emulsion applications in textiles and special applications, along with their demonstrated characteristics and features: 1. Fabric Coating with Acrylic Emulsion: Imparts waterproof properties while maintaining breathability. 2. Nonwoven Fabric Bonding with Acrylic Emulsion: Provides strong adhesion and enhances the strength of nonwoven fabri...
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...
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 ...
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...
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 ...
In many applications, acrylic adhesives do not require the addition of tackifying resins to improve pressure sensitivity, but in most cases, they are necessary: To increase initial tack and peel strength To improve adhesion to low surface energy materials Tackifying resins are commonly used in acrylic emulsion systems, such as paper labels and packaging tapes. They improve peel strength on difficu...
