III. Product Characteristics:
Outstanding Environmental Performance: Utilizing water as the dispersion medium, the product contains no volatile toxic solvents such as benzene or esters. It emits no irritating odors during use and complies with national environmental regulations and the eco-friendly requirements of end products (e.g., environmental standards for toys, food contact packaging, etc.).
Excellent Film-Forming Properties: Forms a uniform, dense film upon drying. The film exhibits good flexibility and tensile strength, resisting cracking or peeling. Demonstrates strong adhesion to various substrates (e.g., metal, plastic, wood, fabric).
Strong Chemical Stability: With an anionic aliphatic polycarbonate core, the product exhibits outstanding resistance to acids, alkalis, and salt spray. It resists yellowing, aging, or decomposition during prolonged use, effectively enhancing substrate weather resistance and corrosion resistance.
High Application Convenience: With moderate viscosity (<1000 mPa・s), the product can be used directly or diluted with deionized water to achieve the desired viscosity for specific application requirements. It supports multiple application methods including brushing, rolling, and spraying, and features fast drying speed to improve production efficiency.
IV. Product Applications:
Paint Industry: Serves as the primary film-forming substance in water-based wood coatings, water-based metal anti-corrosion paints, and water-based plastic paints. Used for surface coating of furniture, appliance housings, automotive components, hardware fittings, and other products to enhance appearance and protective performance.
Adhesive Industry: Suitable for producing water-based composite adhesives and water-based pressure-sensitive adhesives. Used for laminating or bonding materials like paper, film, and fabrics, offering high bonding strength and excellent aging resistance.
Leather and Textile Industry: Serves as a leather finishing agent or textile finishing agent, imparting leather with superior tactile feel and gloss while enhancing textiles' water resistance, abrasion resistance, and wrinkle resistance.
Other Applications: Also functions as a binder for water-based inks and a modifier for architectural waterproof coatings. Specific applications can be tailored to meet customer requirements.
V. Product Packaging:
50KG/drum. Store sealed in a cool, dry environment at 5°C - 35°C, away from direct sunlight.
