Current problems with waterborne polyurethane adhesives: (1) Low solid content: At present, the solid content of water-based polyurethane (WPU) can reach 45%. Fewer systems lead to higher drying and transportation costs. Increasing the solid content leads to an increase in the viscosity of the system, which makes emulsification and dispersion difficult. Reduced emulsion stability. (2) Slow drying ...

Waterborne paint testing and standards:hardness Hardness is one of the most important physical properties of a coating. Coating hardness reflects the coating's ability to resist constant dents, scratches, scribes, and penetrations caused by a hard object. Testing the hardness of materials with different methods will give different results because the testing methods are for different amounts of ma...
