The waterborne polyurethane glue is a polyurethane soluble in water or dispersed in water and the formation of adhesive, it was also known as water-based polyurethane glue as the aqueous polyurethane adhesive or water-based polyurethane adhesive.
The aqueous polyurethane adhesive according to their appearance and particle size, is divided into three categories: the polyurethane aqueous solution (particle size <0.001um, transparent appearance), the polyurethane dispersion (particle size 0.001-0.1um Appearance Translucent), polyurethane emulsion (grain diameter> 0.1, the appearance of whitish).
The biggest advantage of the water-based polyurethane adhesive in water as a basic medium, with a non-flammable, odor, do not pollute the environment, energy saving, easy operation processing advantages, and have people pay attention. Currently, the the waterborne polyurethane core technology by technical barriers and is still being controlled by foreign companies, the higher the cost price of the domestic water-based polyurethane glue, the products varying levels, relatively good the only oriental resins production Deli waterborne polyurethane adhesive.
