Classification of Waterborne Polyurethane Adhesive
Aqueous polyurethane glue refers to the glue formed by dissolving or dispersing polyurethane in water. It is also called waterborne polyurethane waterborne polyurethane or waterborne polyurethane. In practical applications, waterborne polyurethanes are mostly polyurethane emulsions or dispersions, while aqueous solutions are less.

classification of waterborne polyurethane adhesive:
Waterborne polyurethanes on the market can be divided into anionic, cationic and non-ionic types. Mainly anionic.
Waterborne polyurethane is also called waterborne polyurethane, polyurethane dispersion, polyurethane dispersion, waterborne polyurethane resin, waterborne polyurethane coating, etc.
Functional classification and naming of waterborne polyurethane: vacuum blister: also known as blister, PVC vacuum blister, PET vacuum blister, particleboard vacuum blister, wooden door vacuum blister.
Surface treatment agent and coating: also known as fabric surface treatment agent, fabric finishing agent, leather surface treatment agent, fabric coating, etc.
Water-based laminating glue: also known as water-based laminating glue, food packaging laminating glue, plastic laminating glue, PVC laminating glue, PET laminating glue, packaging glue, dry laminating glue, paper-plastic laminating glue, composite glue, plastic laminating glue, etc.
Water-based pressure-sensitive adhesive: also known as polyurethane dispersion pressure-sensitive adhesive, pressure-sensitive tape, etc.
Electrostatic flocking glue: also called water-based electrostatic flocking glue, flocking glue, etc.
With water as the basic medium, waterborne polyurethane has the advantages of non-combustible, low odor, no pollution to the environment, energy saving, convenient operation and processing. It has the advantages of polyurethane adhesive, such as good adjustability, low temperature resistance, good flexibility, high bonding strength and so on.
In addition, compared with solvent-based polyurethane, water-based adhesives have the following characteristics:
1. NCO-free, which means no free isocyanate, completely non-toxic.
2. The viscosity of water-based glue is less than solvent-based glue.
3. Waterborne polyurethane adhesive drying slow.
4. The water-based polyurethane adhesive can be mixed with various water-based resins to improve performance or reduce costs.
5. Waterborne polyurethane glue smell is small, easy to operate, easy to clean residual glue.
