Causes of foaming of glue dripping products

Bubbles should be analyzed from two aspects: one is the bubbles brought in during glue mixing or pouring, and the other is the bubbles produced during curing. In the process of glue mixing, it is easy to bring air into the glue solution because of the high viscosity of the glue or the wrong mixing method. If the viscosity of the glue solution is high, it is difficult to eliminate bubbles. If the viscosity of the glue solution is low and the glue solidifies slowly, bubbles will slowly float to the surface and be eliminated automatically. In order to eliminate bubbles in the process of adjustment and glue injection, vacuum pumping, heating to reduce viscosity, adding diluent to reduce viscosity or adding defoamer can be used to eliminate bubbles.
