Sometimes, a slight ammonia smell is detected in water-based acrylic emulsions, which confuses many people: is this normal or is there a problem? First, we need to clarify that acrylic emulsions themselves do not produce an ammonia smell. However, during their production, ammonia-containing additives may be added to adjust their performance or improve their stability. These additives gra...

Acrylic resins are an indispensable and commonly used resin in water-based coatings. They are widely used in metal coatings, ABS and PC coatings, and glass coatings requiring hardness, especially solid acrylic resins. There are many types of solid acrylic resins. Some solid acrylic resins can be used to produce water-based paints, including the currently popular UV-cured coatings and high-sol...

01 Polyurethane The structure of polyurethane is formed by the reaction of polyisocyanates (e.g., diisocyanate OCN-R-NCO) and polyols (e.g., diol HO-R-OH), where urethane segments are repeating structural units. Polyurethane structures have structures similar to amide and ester groups; therefore, the chemical and physical properties of polyurethane are between those of polyamides and polyesters. S...

II. Types of Acrylic Resins (1) Classification by Thermal Behavior (Film-forming Characteristics): ① Thermosetting Acrylic Resins: Based on acrylic monomers as their fundamental components, these resins undergo further reactions—either among their own functional groups or with active functional groups in other resin systems (such as amino resins, epoxy resins, polyurethanes, etc.)—during the heati...

Leveraging their exceptional surface modification capabilities, water-based acrylic emulsions enhance both the physical properties and printability of coatings applied to paper. When incorporated into a formulation and applied to the paper surface, they form a protective film that improves surface strength, water resistance, and smoothness, while simultaneously reducing ink penetration t...

What is a Water-based Acrylic Emulsion
- 2026-04-08 11:24:34
- admin
Water-based acrylic emulsion is a polymeric emulsion material that utilizes water as its dispersion medium. It is produced through an emulsion polymerization reaction involving vinyl monomers, primarily acrylic esters. Key Features: Environmental Friendliness: With water serving as the dispersion medium, it features extremely low levels of Volatile Organic Compounds (VOCs); it is no...

Acrylic resin synthesis is fundamentally a free-radical polymerization process, consisting of chain initiation, chain propagation, and chain termination, often accompanied by chain transfer throughout the reaction. For thermoplastic acrylic resins, controlling molecular weight and molecular weight distribution is critical. While increasing molecular weight improves the mechanical properties o...
