Emulsion polymerization, developed in the last century, has seen its production volume, quality, and variety of products increase year by year due to its unique advantages, with increasingly rational production processes. Furthermore, emulsion polymerization technology is constantly innovating. Besides conventional emulsion polymerization, various polymerization technologies have emerged, such as ...
I. Why Must Cigarette Packaging Printing Shift to Water-Based Acrylic Emulsions? Traditional solvent-based inks contain large amounts of volatile organic compounds (VOCs) such as benzene and ketones, which not only harm the health of operators but also easily leave residues on packaging, affecting tobacco safety. Water-based acrylic emulsions, using water as the dispersion medium, have extremely l...
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...
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...
Acrylic resins find extremely broad application across various industrial sectors, including coatings, chemical fibers, textiles, adhesives, leather, papermaking, inks, rubber, and plastics. Acrylic Adhesives Acrylic Coatings Superabsorbent Polymers (SAP) Acrylic Rubber (ACM, AEM) Acrylic Plastics: (1) Organic Glass (PMMA) The most prominent variety of acrylic plastics is polymethyl methacryl...
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...
As environmental regulations tighten globally and end users increasingly prioritize health and sustainability, the adhesive industry is undergoing a fundamental shift from solvent‑based to eco‑friendly alternatives. Among the various solutions, waterborne acrylic emulsion has emerged as a leading material due to its excellent balance of performance, versatility, and environmental compatibility. Wa...
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...
In the coatings industry, pure acrylic emulsion and acrylic emulsion (typically meaning styrene-acrylic) are two common waterborne binders. Their main differences lie in composition, performance, and application. 1. Composition Pure acrylic emulsion: Made from 100% acrylic monomers (e.g., butyl acrylate, methyl methacrylate). Acrylic emulsion (styrene-acrylic): Copolymer of styrene and acrylic mon...
