Waterborne polyurethane dispersions (PUDs) are a class of resin systems that combine environmental friendliness with high performance, and are gradually becoming a star material in industries such as coatings, adhesives, textiles, leather, and inks. So, what makes PUDs so special? What performance characteristics do they offer? And in which fields can they be applied? I. What are Waterbo...
This seemingly ordinary milky-white liquid contains immense power to transform the world of materials. In daily life, we rarely notice a chemical product called "acrylic emulsion," yet it's ubiquitous—from home wall coverings to clothing fibers, from packaging materials to wood coatings, this magical emulsion is quietly adding color and convenience to our lives. What is Acrylic Emulsion? Acrylic e...
Environmental Friendliness: Water-based acrylic resins use water as a solvent and do not produce harmful gases or pollutants during use, meeting environmental protection requirements. Weather Resistance: They have good weather resistance and can be used under various climatic conditions, being less susceptible to the effects of ultraviolet light, oxygen, and humidity. Good Adhesion:...
Characteristics of Acrylic Polyurethane Topcoat Acrylic polyurethane paint, formed by the reaction of hydroxyl-containing acrylic ester and aliphatic polyisocyanate such as HDI trimer, has a paint film with excellent hardness and flexibility, and good chemical resistance. Its outstanding weather resistance, high gloss, good drying properties, and fast surface drying without dust adhesion make it t...
Polyurethane materials are a general term for a class of macromolecular compounds that have urethane structures in their molecular structure. They are usually prepared by the polyaddition reaction of diisocyanates and polyols. Polyurethane polymers possess both polar functional groups that allow for physical cross-linking and non-polar and flexible chain segments. When used properly, these po...
One component of self-adhesive label materials is the adhesive, also known as glue. The adhesive determines the label's stickiness and applicable scenarios. The adhesive is also the bonding layer between the label and the object it's applied to; its stickiness, temperature resistance, and magnetic adhesion directly affect the label's adhesion effect. It can be divided into the following categories...
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...
Acrylic resins constitute a broad category of synthetic polymers produced through the copolymerization of acrylate monomers (such as methyl acrylate, ethyl acrylate, butyl acrylate, hydroxyethyl acrylate, etc.) and methacrylate monomers (such as methyl methacrylate—commonly known as the monomer for organic glass or PMMA). I. Core Characteristics and Advantages Excellent Film-Forming Properties: Ca...
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...
As carboxylic acid-type hydrophilic chain extenders, DMPA and DMBA have found widespread application in the production of water-based polyurethanes, thanks to their unique molecular structures and superior performance characteristics. Our company maintains a robust cooperative relationship with our manufacturing partners, ensuring a stable and consistent supply of these products over the long term...

If you are a manufacturer of—or a user of—hot-melt adhesives, you are well aware that while most hot-melt pressure-sensitive adhesives (HMPSAs) appear virtually identical in appearance, the specific manufacturing processes employed during their blending result in distinct sets of advantages and disadvantages. Hot-melt pressure-sensitive adhesives are complex mixtures composed of SBC (Styrene-Butad...
