Many people see that a lot of Teflon coatings used in industry are green, especially when used in molds, let's talk about the reasons. The use of coating characteristics In extrusion or die casting products, generally dark, for example, rubber, silicone and so on, if the coating is made of dark, then whether the coating falls off is more difficult to see. Therefore, made of light color and with br...
1.Touch optimization: the pursuit of softness and fullness In view of the frequent skin-to-skin contact of fabrics, the primary goal of the design of waterborne polyurethane coatings is to achieve soft touch and full form. This requires us to carefully balance the ratio of hard and soft segments in the formulation adjustment, while carefully selecting the types of both to ensure that the coating r...
The grinding fineness of paint is one of the important qualities of color paint, which has a great impact on film forming quality, film gloss, durability, storage stability of paint, etc., and is one of the routine testing items of paint production. The fineness of the paint refers to the size of the particle size or the uniformity of the dispersion of the pigment or the bulk pigment, and the unqu...
Water-based coatings, acrylic resins are commonly used resins that can not be avoided, commonly used metal coatings, ABS, PC coatings, glass coatings that require hardness, most of them will be applied to acrylic resins, especially solid acrylic resins. There are many varieties of solid acrylic resins, and some solid acrylic resins can be used to produce water-based paints, including the popular l...
Gloves are mainly used to protect the skin from harm in People's Daily activities and special environments, and can also be used to play a decorative role in daily life.According to the different production methods, it is divided into knitted gloves, sewing gloves, soaked gloves and so on. Depending on the function, there are flame retardant gloves, welding gloves, non-slip gloves, oil resistant g...
Glove PU coating refers to coating the outer layer of gloves with a layer of polyurethane (PU) material. This coating has a variety of functions, mainly including: Oil and chemical resistance: makes the gloves suitable for work environments where oils and chemicals need to be handled. Anti-slip and wear resistance: Enhances the stability of the gloves in wet or greasy environments, reduces the ris...
Dispersed PTFE is a secondary particle formed by the coagulation of PTFE dispersed particles, with a diameter of 500μm. It is in powder form and has a large specific surface area. After absorbing organic solvents, it forms a paste under the action of shear force. It is usually formed by extrusion molding process, so it is called paste extrusion molding. 1.PTFE dispersion impregnation. Product...
【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...
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 ...
Sinograce Chemical PU series is an anionic aliphatic polyester polyurethane dispersion product, a high-gloss product with a relatively hard feel. It can be used for high-gloss surface treatment of fabrics, leather, synthetic leather, etc. 1. High gloss 2. Excellent yellowing resistance 3. Excellent abrasion resistance Typical properties Appearance: &n...
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...
Many people find themselves torn when selecting materials: since both are used for coatings, which one offers greater durability? Which is the more suitable choice for waterproofing during renovation? In reality, neither possesses an absolute advantage over the other; the key lies in the specific requirements of the application scenario. Today, we will clarify the core distinctions between the two...
Adjusting a water-based acrylic resin formulation is rarely as simple as adding one new material. For example, increasing resin hardness may make the coating film more brittle. Reducing the glass transition temperature can improve low-temperature film formation, but it may also reduce heat resistance and blocking resistance. Increasing the amount of hydrophilic groups may improve emulsion stabilit...
Waterborne polyurethane dispersions, commonly known as PUDs, may appear milky white, translucent, or slightly bluish in the liquid state. This difference is mainly related to particle size, particle size distribution, and how strongly the dispersed particles scatter visible light. In general, milky dispersions scatter more light, while finer dispersions allow more light to pass through. However, a...
Choosing a water-based resin should begin with the application, not with viscosity, solids content, or price. Products with similar technical data can behave very differently in production. A resin may work well on paper but show weak adhesion on plastic film. A coating may form properly under heated drying but remain tacky at room temperature. A low-viscosity polyurethane dispersion may look too ...
As global environmental regulations such as EU REACH and OEKO-TEX® Standard 100 become increasingly stringent, traditional solvent-based PU systems face growing restrictions in protective glove manufacturing. With advantages such as low VOC emissions and no DMFa residue, waterborne polyurethane (WPU) emulsions are rapidly becoming a key choice for glove manufacturers transitioning from solvent...
