Why do small bubbles appear in the composite film?
- 2024-04-19 17:51:28
- admin
"If there are small bubbles in the complex, opaque and foggy, it will not only affect the appearance quality, but also affect the peeling strength of the complex, reducing it, which is a very bad phenomenon." 1.The surface tension of the base film is too small, the infiltration is poor, the glue is not uniform, and the space without glue is empty and bubbles are generated. The solution is to use a...

Film-forming properties of waterborne polyurethane emulsions
- 2024-07-10 16:37:27
- admin
The final state of waterborne polyurethane is a solid film. During the process from emulsion to solid film, accompanied by the evaporation of water and the concentration of water dispersion, the latex particles are close to each other. Before the solid content reaches 74%, the dispersion particles can move in the continuous phase of water. Under the influence of water/air interfacial tension, the ...
