What is the knowledge of waterborne polyurethane?

What is water-based polyurethane? Refers to a new type of polyurethane that uses ionized water or distilled water instead of organic solvents as the dispersion medium. It has many advantages different from solvent-based polyurethanes and has many systems. The following is introduced by ZHEJIANG RUICO ADVANCED MATERIALS CO., LTD., in the context of increasing environmental pollution, various countries have increasingly stringent requirements for VOC emission standards, and new industry regulations are constantly being introduced. The entire resin industry is undergoing an environmentally-oriented transformation. node. Water-based polyurethane uses water as the medium, which is an environmentally friendly product and is widely used. Its performance in all aspects has a lot of changes compared with solvent-based polyurethane.






Advantages of waterborne polyurethane:
(1) Environmental protection and health
Water does not volatilize harmful substances, does not burden the environment, and has no impact on the health of the staff.
(2) Low construction risk
Polyurethane is dispersed in water, not easy to burn, and the probability of accidents is greatly reduced.
(3) Unlimited circulation
Water-based polyurethane is an environmentally friendly product, does not contain toxic organic substances, and its circulation will not be restricted, whether it is foreign or domestic.
(4) Good moisture permeability
The aqueous medium promotes the strong hydrophilicity of polyurethane and good water binding.
(5) Easy to process
Water is used as the continuous phase, and its system solution viscosity is very low, which is very conducive to processing.
(6) High compatibility
