• Sep 10, 2025 Chlorinated Rubber – What is it and why is it used in Paints?
    An odorless, pale yellow resin prepared by adding up to 65% chlorine to an elastomer, such as natural rubber, butyl rubber, or styrene-butadiene. Chlorinated rubber produces a hard tough, glossy film. It is used primarily in the for paints, varnishes, adhesives, inks and paper coatings. Chlorinated rubber is also used for waterproof paints on floors and swimming pools. It is very resistant to chemicals and moisture. Chlorinated Rubber in Paint: Chlorinated rubber paint usually consists of chlorinated rubber resin, modified resin, pigments/fillers, additives, and solvents. Not limited by temperature during construction: chlorinated rubber coatings can be applied in environments ranging from -20 to 50°C, without being limited by season or temperature. Convenient to use: most chlorinated rubber coatings are single can packaging systems, and do not require temporary mixing of other components at the construction site. After opening the packaging drum and mixing it uniformly, the coating can be used. Quick drying: chlorinated rubber coatings are physically drying coatings that dry by solvent evaporation. The solvent release rate is fast, and after painting, it dries quickly into a film. After 4 to 6 hours at room temperature, the second coat can be applied. Thick coating can be obtained: chlorinated rubber thick paste coatings, if sprayed with high-pressure airless spraying, can achieve a dry film thickness of about 55-85μm for each pass. The highest dry film thickness can reach 120μm, so a few less coatings can obtain a thick coating and shorten the construction period. Good adhesion: chlorinated rubber coatings have good adhesion to steel and metal surfaces. At the same time, the solvent in the film-forming material can infiltrate between the layers, making them stick together, thereby enhancing the adhesion between the coating layers. Good anti-corrosion properties: since chlorinated rubber itself is a chemically inert film-forming material, the permeability of the coating film to water vapor and oxygen is ultra-low, only 1/10 of that of alcohol and acid. Moreover, it has good resistance to water, salt, acid, alkali, oxidants, and various corrosive gases. Convenient for maintenance: during maintenance, there is no need to remove the firmly adhered old paint film. The new and old paint films can have mutual dissolution due to the penetration of solvents, which results in strong adhesion. Chlorinated rubber paint can also be applied on some other types of paint films, making maintenance very convenient. Good anti-toxicity and flame-retardancy: due to the high content of "chlorine" polymers in the components of chlorinated rubber coatings, it has the property of inhibiting the growth of poisonous bacteria. If the surface of the equipment encounters a fire source, the coating film can decompose chlorine gas, which has a certain flame-retardant effect. Our goods are equivalent to most of worldwide brand, like Pergut S series. So any more ...

  • Aug 18, 2025 What is water-based acrylic resin emulsion used for?
    Water-based acrylic resin emulsion is a versatile, environmentally friendly binder used in a wide range of products, including architectural paints (interior and exterior), industrial and automotive coatings, adhesives, textile and leather treatments, water-based inks and printing materials, and packaging. These emulsions provide properties like water repellency, durability, abrasion and corrosion resistance, UV stability, and flexibility, making them a popular choice across various industries due to their safety and reduced environmental impact. Key Benefits: Eco-friendly: Water-based formulations are a greener alternative to traditional solvent-based systems, with lower VOC (volatile organic compound) emissions, making them safer for workers and consumers. Versatile: Can be formulated to achieve a wide range of properties, from soft and elastic to very hard and durable. Durable: Provides excellent resistance to water, abrasion, corrosion, and UV light, ensuring a long-lasting finish. Key Applications Coatings: Paints: Used in high-performance and decorative paints for buildings (walls, wood, concrete) due to their durability, flexibility, and resistance to fading and chalking. Industrial & Automotive Finishes: Provide excellent exterior weathering, hardness, and chemical resistance for industrial and automotive applications. Waterproof & Protective Coatings: Formulate materials for protecting concrete and other surfaces from water and environmental damage. Adhesives & Binders: Packaging and Construction: Used in adhesives for paper, wood, and other materials, providing strong bonding properties. General Purpose: A common binder in various industries for its strong adhesive capabilities and minimal environmental impact. Inks and Printing: Water-based inks: Formulate inks for various printing applications, offering properties like high gloss and wear resistance. Graphic Arts: Found in artists' paints and other graphic arts materials.

  • Jul 23, 2025 Property and applications of VC-Copolymer MP 60 Resin
    Property: MP-60 resin is made from vinyl chloride and vinyl isobutyl ether through copolymerization, the resin possesses good adhesive property because of the vinyl isobutyl eth-er component. It possesses acid resistance, alkali resistance, salt resistance and chemical corrosion resistance because there are no saponifiable ester bonds in the molecular structure. The flexibility of coating film and the solubility of resin are very good because of the isobutyl eth-er in the structure. Meanwhile, there are no reactive double bonds in the structure, so the resin isn’t easily oxidized or degraded. The film of coating added MP60 has atmospheric ageing resistance, good light fastness, and the film won’t easily occur yellowing and pulverization. Solubility: MP-60 resin is easily soluble in the following solvents, such as aromatic hydrocarbons, chlorohydrocarbons, esters, ketones, glycol eth-er acetates and some alcohol eth-ers etc. MP resin has specially excellent solubility in aromatic hydrocarbons, it can dissolve in 20% toluene (xylene) solvent at normal temperature. Compatibility & Miscibility: MP-60 resin is miscible or partly miscible with the following copolymers, such as vinyl chloride copolymers, polyacrylates, unsaturated polyester resins, aldehyde resins, petroleum resins, natural resins, alkyd resins modified through oil and aliphatic acid, dry oil, tar oil and asphalt etc. Applications: MP-60 can be applied in the base resin of coatings in the following fields: Steel structure, containers, marines and those equipment working in the water, machinery and automobile engineering, transportation facilities, construction protection etc.
