Compared with the solvent-based two-component polyurethane wood coating, the water-based resin of the two-component water-based polyurethane coating has a very low V O C content, which can be reduced by 70% to 90%, and the drying speed is fast. Gloss, physical and chemical properties and service lif... read more
There are many principles for the adhesion of water-based polyurethane resins to metal surfaces. Such as mechanical occlusal bonding theory, electrostatic theory, adsorption theory, diffusion theory, acid-base use theory and chemical bond theory. In general, adhesion is the result of a combination o... read more

In recent years, water-based polyurethane has become more and more popular. With the advantages of safety, environmental protection, odorless, transparency, color, and easy cleaning, it quickly eliminates the previous paints with pungent odor and harmful substances to the body. Then let everyone kno... read more
In order to adjust the viscosity of the polyurethane adhesive to facilitate the process operation, a solvent is often used in the preparation and use of the polyurethane adhesive. Through the dilution of the solvent, the adhesive can be better coated on the composite film. Most of the current polyur... read more
