Product Description

Product Description

Product Overview

This product is an anionic water-based polyurethane emulsion, encompassing various series including aliphatic polyether, aliphatic polycarbonate, aromatic polyether, and self-matting types.  Synthesized using advanced polymerization technology by Shandong Jiurunfa Chemical, it offers customized modification solutions such as polycarbonate modification, silicone modification, and polyester-polyether composite modification. The emulsion has a milky white, bluish transparent, or translucent bluish-white appearance, is free of mechanical impurities, and has a stable pH of 7-8.  It contains no added solvents, has extremely low VOC content, meets environmental standards, and is highly safe, making it an excellent alternative to traditional solvent-based polyurethanes.

The product combines the excellent flexibility, wear resistance, and hydrolysis resistance of polyurethane. Depending on the series, it can achieve specific characteristics such as high elasticity, high hardness, yellowing resistance, and self-matting properties. After film formation, the gloss is controllable (high gloss to matte <0.6), with excellent leveling and strong adhesion. It is widely applicable to various industries such as coatings, adhesives, leather finishing, and textile processing, offering a balance of cost-effectiveness and high performance to meet diverse needs in different scenarios.

Product Advantages

• Comprehensive Product Range, Tailored to Your Needs: Covering a wide range of series including aliphatic, aromatic, self-matting, and adhesive-specific types, with adjustable solid content from 30% to 56%, elongation at break up to ≥2200%, and hardness (modulus) selectable from 0.3MPa to 30MPa.  It can meet both the softness requirements of leather finishing and the high hardness and wear resistance demands of coatings.
• Outstanding Core Performance: Possesses excellent hydrolysis resistance, water resistance, and abrasion resistance.  The aromatic series offers exceptional cost-effectiveness, and the self-matting series has a gloss level of ≤0.6, providing a delicate and dry feel.
• Environmentally Friendly and Safe: Non-hazardous material, odorless, with no safety hazards during transportation and use.  It aligns with global environmentally friendly production trends and meets the green certification requirements of downstream enterprises, suitable for fields with strict environmental requirements such as furniture, leather, and food packaging.
• Strong Stability, Easy Storage and Use:  Utilizes an ionic stabilization system, with a shelf life of up to 12 months under sealed storage at room temperature.  No stratification or precipitation occurs after 30 days of storage at a constant temperature of 50℃. It can be directly diluted with water and supports various application methods such as spraying, roller coating, and brushing, without complex pre-treatment.
