Water-based polyurethane adhesives use water as the dispersion medium. Their core advantages lie in environmental friendliness and safety, ease of application, performance compatibility, and controllable cost. They are an ideal environmentally friendly alternative to solvent-based adhesives.
I. Environmental Protection and Safety Advantages (Core)
Using water as the medium, it contains no VOCs, is non-toxic and non-flammable, has low odor, and there is no solvent evaporation pollution during production and use. It does not harm human health and complies with global environmental protection regulations. During storage, transportation, and construction, there is no risk of flammability or explosiveness, significantly reducing safety hazards, and it is suitable for substrates that are easily eroded by organic solvents.
II. Convenience in Construction and Usage
Low viscosity, easy to adjust. It can be adjusted by water or thickening agent to control the construction state, suitable for various processes such as brushing, spraying, and roller coating. The construction tools and leftover glue can be cleaned with water, making the operation simple and the cleaning cost low; the solid content can reach up to 50%, providing a large adjustment space for the formula, and suitable for different process requirements.
III. Excellent Adhesion and Film Formation Properties
It retains the characteristics of high bonding strength, good flexibility, low-temperature resistance, and chemical corrosion resistance of polyurethane. It has strong adhesion to various substrates such as metals, plastics, fabrics, and woods. The film formation is continuous and uniform, featuring impact resistance, wear resistance, water resistance, and oil resistance. It can be adjusted in hardness and is suitable for different scenarios in terms of mechanical and environmental requirements.
IV. Modification and Cost Advantage
It can be mixed and modified with various water-based resins such as water-based acrylic and water-based epoxy resin, enabling flexible optimization of performance and reduction of raw material costs. The water resource utilization rate in the production process is high, which is more energy-efficient and cost-effective compared to solvent-based products, and the long-term overall cost is more favorable.
