What's the difference between acrylic resins used in adhesives and acrylic resins used in coatings
- 2025-10-21 17:44:26
- admin
Acrylic resins used in adhesives differ from those used in coatings in the following ways: Performance Characteristics Acrylic resins used in adhesives High bond strength: They must form a strong bond between different materials and cure quickly to generate sufficient cohesive and adhesive strength. For example, α-cyanoacrylate adhesives cure in seconds, achieving fast bonding. Good flexibility: W...

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 ...

- 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...

Tackifying Resins
- 2025-12-04 16:03:44
- admin
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...
