First, pour the glue on the flat glass to observe its rheology, and swing it from side to side to observe its rheology. If the glue flows too fast, the glue is too thin. Poor fluidity, too thick is not conducive to bonding.
Second, dip it with your hand to observe its viscosity. If you can draw slowly, a little sticky hand is better.
Then, pour on a small piece of glass to see how long it takes to form a film. If it is about 1 to 2 minutes, the glue that can form a film on the surface of the glue has a better film forming time.
The fourth step, after the glue after the film is basically cured, dip your finger in water to purify it and observe its cohesion. If the glue is dissolved quickly - cohesion is poor. The glue is cloudy when it's drained -- it's filled.
Finally, the two plates are staggered and glued together, and the tension is measured 24 hours later. Let it soak for a day and then dry it to see how the color changes. If the tension of the glue changes very little, it means that the water resistance of the glue is very good, and the reverse is very poor.
