Water-based polyurethane resin 3909500000
With its stable physicochemical properties, water-based polyurethane resin is compatible with a wide range of precise formulations and complex application conditions, making it a core raw material in the fields of paints, protective coatings, flexible materials, and adhesives. Relying on mature polymerization and synthesis processes, Jiurunfa strictly controls all physicochemical indicators of its products, ensuring consistent and stable performance across batches and maximizing the retention of the product’s inherent high-quality characteristics.
In terms of basic physical properties, water-based polyurethane resin uses pure water as a dispersion medium. It appears as a uniform milky-white or slightly translucent emulsion with a uniform particle size distribution for both the powder and emulsion, free of coarse particles, lumps, or impurities. The product exhibits excellent flowability and rapid dispersion upon addition; it requires no organic solvents to aid dissolution and rapidly blends with water-based systems at room temperature without agglomeration or scum formation, making it suitable for automated feeding and continuous production lines. At the same time, the product exhibits excellent film-forming properties, self-drying at room temperature, and good leveling. After curing, the paint film is dense, smooth, and highly transparent, free of surface defects such as pinholes, orange peel, or brush marks. Its adaptability to base coat applications far exceeds that of ordinary water-based resins.
Its core chemical properties form the product’s key competitive advantage. First is the balance of rigidity and flexibility in its mechanical properties. The unique molecular chain structure of polyurethane gives the cured paint film both hardness and elasticity, making it resistant to bending, tensile stress, and abrasion. It can withstand everyday friction and scratches while also expanding and contracting with the substrate, effectively preventing issues such as cracking, peeling, and flaking of the paint film. Second, it offers excellent chemical resistance and weather resistance. Once cured and formed into a film, the molecular structure remains stable with extremely low porosity, effectively blocking moisture, oil, and corrosion from weak acids and alkalis. Even with long-term use, it is resistant to loss of gloss, yellowing, and chalking, ensuring stable and reliable long-term protection.
At the same time, water-based polyurethane resin possesses exceptional interfacial wetting and adhesion properties. It exhibits excellent penetration and adhesion to a wide range of substrates, including wood, metal, plastic, leather, and textiles, resulting in a film with strong adhesion that is resistant to delamination and blistering. The product has broad chemical compatibility and mild, stable physical and chemical properties. It can be blended normally with acrylic emulsions, various additives, pigments, and fillers without flocculation, emulsion breakdown, or system separation. It offers significant flexibility in formulation adjustment, making it suitable for the development of various customized products.
In terms of environmental and physical-chemical characteristics, this product is solvent-free and contains no free harmful substances. It has extremely low VOC content, a mild odor, and is safe and non-toxic, fully complying with green chemical production standards. It is suitable for applications with high environmental requirements, such as home decoration, enclosed spaces, and children’s products. Under normal conditions, it exhibits strong chemical inertness and is resistant to issues such as auto-polymerization, deterioration, and decomposition. The system remains stable across a wide pH range and does not experience performance degradation due to minor environmental fluctuations, ensuring extremely high overall formulation safety and stability.
In terms of storage and transportation, this product exhibits excellent environmental adaptability and stability. It can be stored for long periods in a standard, sealed, cool, and dry environment; it is not prone to moisture absorption or separation and settling, and storage losses are extremely low. The product is not classified as a highly hazardous material, so transportation safety requirements are low. It offers excellent cold resistance and freeze resistance, making it suitable for logistics operations across diverse climatic conditions from north to south. It is unlikely to demulsify or deteriorate during long-distance transport, significantly reducing risks associated with warehouse management and logistics supply for businesses.
Jiurunfa possesses a mature synthesis process and a standardized, closed-loop quality control system. The company strictly controls the physical and chemical properties of every batch of water-based polyurethane resin to eliminate performance fluctuations and ensure the product’s core qualities of high stability, high compatibility, and high environmental friendliness.
