Description
Polyurethane PU adhesive waterborne
The main advantages of water-based polyurethane adhesives:
- Excellent environmental performance: Water-based polyurethane uses water as a solvent and does not contain organic solvents (VOC), so it is pollution-free, safe and reliable. It can replace oil-based adhesives.
- Excellent mechanical properties: Waterborne polyurethane adhesive has good bonding strength and initial adhesion, and is suitable for bonding a variety of materials
- Good storage stability: Waterborne polyurethane adhesive has good storage stability and can maintain its performance for a long time.
- Good medium resistance: The adhesive has good water resistance, freeze-thaw resistance and high temperature resistance
- Fast drying speed: At low ambient temperature, waterborne polyurethane adhesive has good film-forming properties and a fast drying speed
- Good construction process: The construction process of waterborne polyurethane adhesive is simple, its viscosity is low, it can be adjusted with water-soluble thickeners and water, it is easy to operate, and residual glue is easy to clean
- In addition, waterborne polyurethane adhesive can be mixed with a variety of waterborne resins, which is conducive to improving performance and reducing costs, but attention should be paid to ionic properties and acidity and alkalinity to prevent coagulation
- Chemical properties: Waterborne polyurethane adhesive contains carboxyl, hydroxyl and other groups, which can participate in the reaction under suitable conditions to produce cross-linking and improve performance
Application areas:
Waterborne polyurethane PU adhesive is widely used in various fields, including the shoemaking industry, automobile manufacturing, wood processing, etc.
