This modified multifunctional aqueous vinyl acetate-vinyl copolymer emulsion (abbreviated as Modified emulsion) is a high-performance waterborne coating and adhesive product. It uses advanced modification technology to make the emulsion has excellent fluidity, wettability and adhesion to various polymer films, coatings and other difficult to handle substrates. The emulsion is not only environmentally safe, but also convenient for construction, and is widely used in non-woven fabrics, textiles, leather, wood and other fields.
Product characteristics
Excellent fluidity: The modified emulsion has excellent fluidity and can easily penetrate the surface of the substrate to form a uniform coating.
Excellent wettability: The emulsion has good wettability on the substrate, and can quickly diffuse and cover the surface of the substrate, improving the coating quality.
Strong adhesion: Through modification technology, the polymer molecular chains in the emulsion are able to form strong chemical bonds with the surface of the substrate, providing strong adhesion.
Environmental protection and safety: The water-based formula does not contain harmful substances, meets the requirements of environmental regulations, and is safe and non-toxic.
Convenient construction: the emulsion is easy to dilute and mix, and can be sprayed, dipped, rolled and other construction methods.
Application fields
Non-woven fabrics and textiles: can be used for non-woven fabrics and textiles surface coating treatment, improve waterproof, oil, wear and other properties, while giving products good feel and appearance.
Leather products: It can be used for the surface coating and protective treatment of leather products to improve the durability and beauty of leather.
Wood products: can be used for waterproof, moisture-proof, mildew resistant treatment of wood products, while enhancing the hardness and wear resistance of wood.
Coating industry: can be used as a coating additive or base material, improve the fluidity and wettability of the coating, improve the coating quality.
Instructions for use
Dilution: According to the specific construction needs, the emulsion can be diluted to the appropriate concentration before use. It is recommended to conduct a small sample test before use to determine the optimal dilution ratio.
Construction: The emulsion is evenly coated on the surface of the substrate by spraying, dipping and rolling coating. During construction, the surface of the substrate should be clean, dry, and free of oil and impurities.
Drying: Under the appropriate temperature and humidity conditions, the water in the emulsion evaporates to form a uniform coating. Drying times and conditions can be adjusted according to the specific product and construction environment.
Post-treatment: If necessary, post-treatment operations can be performed, such as drying, calendering, etc., to improve the quality and performance of the coating.
Precautions
Storage conditions: The emulsion should be stored in a cool, dry, ventilated warehouse, away from direct sunlight and high temperature.
Shelf life: The shelf life of the emulsion is XX months under specified storage conditions. After expiration of the shelf life, it should be re-inspected before it can be used.
Safe operation: During use, you should wear protective glasses, gloves and other protective equipment to avoid splashing into your eyes or skin. If accidentally splashed into eyes or skin, rinse immediately with water and seek medical attention.
Construction environment: The construction should ensure that the environment is clean, dust-free, no oil and impurities to improve the quality of the coating. At the same time, avoid construction in wet, cold or high temperature environments.
The process of making VAE emulsion
Main raw materials: The main raw materials of VAE emulsions include polyvinyl lactate (or polyvinyl acetate), which is the main component of the emulsion resin and directly affects the performance of the emulsion.
Auxiliary raw materials:
Emulsifier: used to emulsify polyvinyl lactate to form an emulsion state. The selection of emulsifier should consider its compatibility and stability with emulsion resin.
Stabilizer: Used to increase the stability of the emulsion and prevent the stratification and condensation of the emulsion. Common stabilizers are polymers, hydrophilic colloid and so on.
Additives: such as dispersants, thickeners, etc., used to improve the performance of the emulsion, such as increasing the dispersion of the emulsion, increasing viscosity and improving rheological properties.
Other additives: such as mildew protection agents, toughening agents, etc., used to meet specific needs or improve product performance.
