VAE Emulsion For Architectural

The formulation and production process of vae emulsion waterproofing materials involve a variety of ingredients and steps.   Formulation: The main component of VAE emulsion is vinyl acetate copolymer, which provides adhesiveness, stability and elasticity, as well as emulsifier, defoamer, stabilizer and auxiliary agent. These ingredients help to form a stable emulsion state, increase its adhesion and durability, and depending on the specific application needs, additives such as thickeners and preservatives may be added.   Production process: The production process includes raw material preparation, mixing, heating, emulsification, pH adjustment and adding additives. First of all, the ethylene acetate copolymer and other raw materials are added to the reaction kettle, adding an appropriate amount of water to stir and mix, and then heating to a certain temperature to start the polymerization reaction, adding emulsifier through stirring and high-speed shear to form a stable emulsion, adjust the pH value according to the need, and finally add additives, packaging and sealing.    In addition, there are other ingredients such as polyurethane emulsion, thickener, dispersant, etc., used to improve the bond strength, durability, softness, wrinkle resistance and so on. These ingredients are widely used in different fields such as building materials, textile printing and dyeing, paper industry, coatings industry and adhesives.   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.   Related Products: VAE CW 40-705 VAE CW 40-707 VAE CW FH-Ⅱ

The ethylene segment is introduced into the VAE emulsion molecule, which acts as a plasticizer and reduces the glass transition temperature and film-forming temperature, thus giving the VAE emulsion adhesive many excellent properties. 1. It has good initial tack, wet tack and fast curing speed. It can harden the conjunctiva in 5-10 minutes at room temperature. So it is stable in storage. 2. The cured adhesive film is colorless and transparent, flexible and not brittle, with good resilience and an elongation of up to 600%. 3.  Good water resistance, alkali resistance, wear resistance, creep resistance, freeze-thaw resistance. The performance of VAE film will not change even after being soaked in weak alkali and weak acid media for 1 year. 4. Good weather resistance, UV resistance, not easy to oxidize and age. 5. It is non-toxic, odorless and harmless, suitable for hygiene and food purposes. It can be used to produce hygiene materials, such as sanitary napkins, diapers, medical cloths, wipes, surgical caps and other disposable cloths and food packaging. 6. Good compatibility with other water-based adhesives. And it is easy to modify to obtain new properties. 7. Low surface force, suitable for bonding materials with low surface properties, such as PE, PP, PS, etc. 8. It has strong adaptability and excellent adhesion to a variety of materials, especially film products such as PVC, PET, PA, etc. 9. The dry adhesive film after the water has evaporated can be hot-melt sealed at a heat sealing temperature of 82-90°C. 10. It is easy to apply and clean glue, convenient and safe to use.   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.
