Waterborne polyurethane is often used in the preparation of waterborne coatings because of its excellent film formation and adhesion, excellent flexibility and wear resistance.However, water-based polyurethane dispersion contains a lot of surfactant, easy to produce bubbles, and because of the special properties of water-based polyurethane, it is necessary to use the characteristics of water-based...
The bonding effect can be achieved by applying pressure for a short time (non-aqueous solvent heating) It overcomes the solvent volatilization and drying time needed during the operation of structural adhesive, and can improve the working environment After stripping, it can be corrected without contamination and can be reused for many times Easy to operate, can greatly improve the production effic...
First, pour the glue on the flat glass to observe its rheology, and wiggle it to observe its rheology,If the flow of glue is too fast, it means that the glue is too thin and poor, and too thick is not conducive to bonding. Secondly, with a hand dip to observe its viscosity if you can slowly draw, a little sticky hand is better. Then, pour it on a small piece of glass to observe its film forming ti...
