Water-based polyurethane resin 3909500000
In the realm of coatings and adhesives, polyurethane has consistently occupied the pinnacle of the performance pyramid. Its molecular structure contains a unique urethane bond, where intense hydrogen bonding interactions form between these chemical bonds. This creates a physical cross-linking network within the coating film, resembling countless microscopic springs. When the coating film is subjected to external tensile forces, these hydrogen bonds can first break to absorb energy. Once the external force is removed, they rapidly reconnect. This unique self-healing capability endows polyurethane materials with remarkable abrasion resistance, flexibility, and elasticity. Shandong Jiurunfa's water-based polyurethane resin (Customs Code: 3909500000) represents the successful transfer of these top-tier properties from solvent-based formulations to a water-based system, proving that environmental friendliness no longer requires sacrificing performance.
For many years, high-performance coatings often meant heavy reliance on organic solvents. Oil-based polyurethane finishes delivered durable wood floors, but the pungent smell of toluene and xylene lingered for days after application. Oil-based polyurethane adhesives created sturdy athletic shoes, yet workers in production facilities had to wear gas masks during manufacturing. The advent of water-based polyurethane resins has revolutionized this landscape. We replace organic solvents with water as the dispersion medium, allowing polymer particles to remain stably suspended in an aqueous emulsion. During application, water evaporation causes polymer particles to fuse into a film, with hydrogen bonds reforming. The resulting coating film delivers performance fully comparable to solvent-based products, yet the entire process involves only water evaporation—no solvent emissions.
Wood coatings represent the domain where water-based polyurethane resins demonstrate their greatest advantages. Solid wood furniture and flooring demand exceptionally high coating standards: the finish must be transparent and beautiful to showcase wood grain while also being highly resistant to abrasion, scratches, and heat. When used in wood primers, our water-based polyurethane resin rapidly penetrates wood vessels to seal pores, preventing underlying coatings from sinking. When used in topcoats, they form a tough protective layer with high hardness—resistant enough to withstand steel wool scrubbing without leaving marks—while maintaining flexibility to prevent cracking upon impact. Waterborne polyurethanes excel in transparency: they enhance the depth of dark woods and preserve the freshness of light woods, never obscuring the natural grain. For children's furniture, it's eco-friendly and non-toxic, safe even if chewed on. On kitchen cabinets, it resists grease stains, cleans easily, and withstands long-term use.
The leather finishing industry demands near-perfect materials. Transforming raw hide into a smooth, refined leather product requires numerous finishing steps. The base coat must adhere tightly to the leather surface without peeling. The intermediate coat conceals imperfections while preserving the leather's natural grain texture. The topcoat provides abrasion resistance, withstands wet and dry wiping, and delivers a comfortable feel. Our water-based polyurethane resin can be used for every coating layer. By adjusting the ratio of soft and hard segments and molecular weight distribution, we can produce formulations ranging from extremely soft to extremely hard. When applied to upholstery leather, it flexes with the leather without cracking, leaving no imprints after sitting or reclining. For automotive leather, it offers weather and light resistance with minimal aging, withstanding summer sun exposure and winter freezing temperatures. On shoe upper leather, it delivers abrasion resistance and durability, while different hand feel agents can be combined to achieve silk-like, wax-like, or skin-like textures.
Industrial flooring represents another critical application for water-based polyurethane resins. Factory workshops, parking lots, and warehouses subject floors to vehicle碾压, cargo impacts, and chemical corrosion. While traditional epoxy flooring offers hardness, it tends to be brittle and cracks when the substrate does. Water-based polyurethane flooring combines hardness with elasticity, accommodating thermal expansion and contraction of the substrate to a certain degree. Its exceptional wear resistance ensures long-term durability even in workshops with frequent forklift operations. Superior chemical resistance prevents staining from spilled engine oil, diesel, or dilute acids/alkalis. In food processing areas, its seamless, dust-free, eco-friendly properties meet food safety and hygiene standards. On laboratory benchtops, it resists corrosion and facilitates easy cleaning—spilled reagents wipe away effortlessly. On parking ramp surfaces, its slip-resistant, wear-resistant properties ensure safe vehicle access.
Water-based polyurethane resin continues to expand into new application frontiers. In the ink industry, it produces printing inks with strong adhesion and abrasion resistance, ideal for printing flexible packaging like food bags. In adhesives, formulations using this resin yield shoe glues with powerful bonding strength and excellent heat resistance. Sneakers bonded with this adhesive on production lines withstand rigorous testing without delamination. In synthetic leather production, it serves as a coating material, imparting a more authentic feel and superior durability to artificial leather. When used in apparel and luggage, the results are virtually indistinguishable from genuine leather. In textiles, fabrics treated with it achieve waterproofing, breathability, and elasticity, making them ideal for outdoor clothing that excels in both functionality and comfort. Each new application requires targeted adjustments in resin formulation design. Our technical team is committed to exploring further possibilities alongside our clients.
