VAE Emulsion acts as a binder, providing exceptional stability and enhancing the performance of various end products.   One of the notable applications of VAE Emulsion is in the production of adhesives. Due to its excellent adhesion properties, VAE Emulsion is widely used in industries such as woodworking, paperboard lamination, and packaging. The high bonding strength and flexibility of VAE Emulsion enable it to deliver durable and long-lasting adhesion, ensuring the integrity of bonded surfaces.   In the world of architectural coatings, VAE Emulsion plays a crucial role as a binder. It is known for its exceptional film-forming abilities, providing coatings with excellent weather resistance, water repellency, and durability. Moreover, VAE Emulsion enhances the color stability and gloss of coatings, resulting in a visually appealing finish. Its versatility allows it to be used in various coating systems, including exterior paints, interior wall paints, and textured coatings.   Construction materials also benefit from the extraordinary properties of VAE Emulsion. It can be combined with cement, gypsum, or other powders to produce VAE Redispersible Powder. When used in tile adhesives, grouts, and self-leveling compounds, VAE Redispersible Powder enhances workability, water retention, and adhesion strength. This combination ensures reliable performance in demanding applications, such as tile installation and repair.   While the quality of the product itself is essential, exceptional service adds significant value to the overall customer experience.

VAE emulsion is the abbreviation of vinyl acetate-ethylene copolymer emulsion. It is a polymer emulsion formed by emulsion polymerization of vinyl acetate and ethylene monomer as basic raw materials with other auxiliary materials.‌The production process of VAE emulsion mainly includes the following steps‌: The main raw materials of VAE emulsion include ethylene, vinyl acetate, emulsifier and initiator. Ethylene can be made from naphtha or natural gas; vinyl acetate is made from the reaction of ethylene and acetic acid.   After mixing ethylene and vinyl acetate in a certain proportion, they are passed into the reactor, initiators and emulsifiers are added, and emulsion polymerization is carried out under appropriate temperature and pressure. Control the reaction speed and temperature to completely convert the monomer and generate VAE emulsion‌.   The generated VAE emulsion needs to be degassed to remove unreacted monomers and low molecular volatiles. Adjust the pH value of the emulsion to make it more stable, and perform filtration to remove impurities and solid particles in the emulsion.   Put the processed VAE emulsion into a special container, seal it and store it away from direct sunlight and high temperature environment.   The production and use of VAE emulsion (CW 40-600 & ECO VAE 1608) must comply with national and local environmental protection standards, including emission standards for waste water, exhaust gas, noise, etc. Waste water, waste gas and other waste generated during the production process need to be effectively treated and discharged to ensure compliance with environmental protection requirements.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.

Vinyl acetate-ethylene copolymer (VAE) emulsion is the abbreviation of vinyl acetate-ethylene copolymer emulsion. It is a polymer emulsion formed by copolymerizing vinyl acetate and ethylene monomers with other auxiliary materials through emulsion polymerization.   White latex is a water-soluble adhesive, a thermoplastic adhesive produced by polymerization of vinyl acetate monomer under the action of an initiator. Usually called white latex or PVAC emulsion for short, the chemical name is polyvinyl acetate adhesive, which is synthesized from acetic acid and ethylene to vinyl acetate, with the addition of titanium dioxide (low-grade ones add light calcium, talc, and other powders). It is then made by emulsion polymerization. A thick milky white liquid.   VAE emulsion has the advantages of permanent softness, water resistance, low temperature resistance, fast bonding speed, high bonding strength, and is safe and non-toxic. VAE emulsion( CW 40-705) is widely used in adhesives, exterior wall insulation, building waterproofing, coatings, composite packaging materials, building cement mortar modification, non-woven fabric manufacturing, paper coating and general adhesive for various polar and non-polar materials. Access and other fields.   The characteristics of white latex include normal temperature curing, fast curing, high bonding strength, good toughness and durability of the bonding layer and not easy to age. White latex is a widely used water-soluble adhesive. It is mainly used in wood bonding, construction industry, coatings, etc. It is also used in furniture assembly, surface repair, etc.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.

Modification of inorganic cementitious materials such as cement with polymer emulsion has been widely used. Since the water in the emulsion will immediately react with the cement after mixing the two and finally solidify, a two-component form is used in most cases. , measure and mix each component in proportion at the construction site. This brings inconvenience to the storage, transportation and construction of materials. The emergence of re-dispersible emulsion powder has changed the above phenomenon. Redispersible latex powder is a micron-sized thermoplastic resin powder obtained by spray-drying a polymer emulsion to remove water. It can be reduced to an emulsion after adding water.Due to this characteristic, it is widely used in single-component JS waterproof coatings, polystyrene board bonding mortars for building insulation, flexible surface protection mortars, polystyrene particle insulation coatings, ceramic tile adhesives, self-leveling mortars, dry-mix mortars, etc. It is widely used in fields that require modification of inorganic cementitious materials.   RDP is a polymer powder produced by spray drying of polymer emulsion. Polymer emulsions are mostly oil-in-water systems in which thermoplastic polymers with a solid content of about 50% are evenly distributed in water with fine particles (0.1-10 μm). After losing water, the polymer particles first form dense spheres and accumulate on the surface. Under the action of energy, discrete polymer particles form a continuous polymer body. To produce redispersible latex powder by the spray drying method, a layer of PVA protective film is added to the surface of the polymer in advance. Due to the existence of the protective film, the dry powders cannot merge. In order to prevent the rubber powder from agglomerating, some fine mineral powders are also added. , such as clay, etc. However, when redispersible latex powder is mixed with alkaline substances such as cement and water, the PVA(PVA 088-35 & PVA 2088)will be saponified and adsorbed by the quartz in the sand and removed. The rubber powder that has lost its protective film can eventually form a continuous water-insoluble polymer. membrane.   The particle size of the rubber powder (5-250 μm) is much larger than the particle size of the polymer dispersed phase in the emulsion (0.1-10 μm), indicating that the latex particles will agglomerate during the spray drying process. In order to reduce the tendency of polymer powder to agglomerate during long-term storage, inert fluid materials such as clay, talc, silica and other fine particles are usually added to the dry powder as anti-stick fillers. The filler is determined according to the type of polymer and its glass transition temperature. The dosage is generally 8%-30% of the dry polymer powder, which is the main source of ash in redispersible latex powder. After redispersible latex powder is redispersed, the diameter of the latex particles becomes about (0.1-10μm).   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.
