1. The viscosity of the shadowless glue has no relationship with the strength. When the liquid is moved by an external force, a measure of the frictional resistance between the molecules is called viscosity. The greater the frictional resistance, the greater the viscosity; the smaller the frictional resistance, the lower the viscosity.
2. Shadowless glue performance and characteristics: fast curing, controllable reaction; no solvent, no pollution; more suitable for automated operation; wide range of bonding, high bonding strength, wide use. These need to pay attention to of.
3. The whitening phenomenon of shadowless glue is a common problem, but because the whitening phenomenon is not serious, the film is thinner and generally difficult to find. This problem is more or less present in the glass glue metal UV glue on the market. Take a glass plate, drop the glue on it, then put it under the light for 12 minutes, take it out and observe it, so you can quickly detect the whitening phenomenon of UV glue.
4. The viscosity and strength of the shadowless glue are not directly related. If the viscosity is understood as the strength is wrong, it is a misunderstanding of understanding.
5. The curing speed of shadowless glue, especially the positioning speed, has always been a data that consumers are more concerned about. Measuring the quality of UV glue is multifaceted: positioning time, depth of cure, strength, flexibility of the film, etc. are all aspects of assessing the quality of UV glue.
