Performance advantages of water-based PU resin

Water-based PU resin is a polyurethane system that uses water instead of organic solvents as the dispersion medium. It is a new type of environmentally friendly polymer material.Because of its excellent environmental protection, excellent mechanical properties, and good compatibility with other water-based resins,water-based PU resin is widely used in adhesives, coatings, and coating products.What are the performance advantages of water-based PU resin?

1. Because the dispersion medium is water, it is non-toxic, not easy to burn, does not pollute the environment, is energy-saving, safe and reliable.Safe transportation and good working environment.There is no toxic -NCO group in the system, the product has no toxic solvent residue, and the product is safe and environmentally friendly.

2. The moisture permeability and breathability of water-based PU resin is much better than that of similar solvent-based PU products. Because water-based PU resin is highly hydrophilic, it has a strong ability to combine with water, and the product has good moisture permeability and breathability. .

3. Water serves as a continuous phase, so that the viscosity of the water-based polyurethane system has nothing to do with the molecular weight of the polyurethane resin, and is lower in viscosity than solvent-based PU with the same solid content, making it easy to process and operate.

4. The water-based Polyurethane resin system can be blended or copolymerized with other water-based emulsions, which can reduce costs or obtain PU emulsions with more diverse and excellent properties.

5. Water-based PU resin has good film-forming properties, strong bonding, cold resistance, water resistance, solvent resistance and wear resistance.Its adjustable softness and hardness greatly expands the application fields of water-based PU resin. Hard water-based PU can be used as water-based floor paint, water-based wood paint, and soft water-based polyurethane can be used as a soft coating for fabrics, etc.
