The correct treatment of epoxy Ab gumming bubbles

Usually when you use epoxy adhesive, it will produce the most annoying bubbles, because the bubbles will not only seriously affect the appearance, but also cause the glue to not set, and the consequences will be serious. But what if in our life, we encounter epoxy ab glue bubble?

The treatment of epoxy ab gumming bubbles

1、 gently stir A and B to mix

A, B two kinds of liquid in the mixing process will also produce a lot of bubbles, not too strong, so the mixing can rest for a period of time, especially do not pump the air to a vacuum state, do not use immediately. Heat curing time do not add the temperature is very high, because the high temperature will make the gel on the surface of the glue, it will make the bubbles can not be exhausted, rather than a suitable temperature will use the glue viscosity is very thin, the curing process is relatively slow, the exothermic reaction is very small, the foam and foam can easily be washed out of the low viscosity of the material, according to our experience, the temperature of 30 to 35 degrees is best after 5 hours of healing .

2、 heat epoxy AB glue to release bubbles.

The air temperature is low, the viscosity of the material is large, especially in winter, the foam is not easy to discharge, for this problem, you can use in crystal glue A /B two fluids are in different heating containers, the liquid can be added to more than 80 degrees to 100 degrees, liquid B can be heated to 50 degrees to 80 degrees, the viscosity of the glue is reduced, the foam is released, but it must be noted that the heating glue liquid must be cooled below 30 degrees mixed two doses of A B glue. Otherwise, the solidification liquid phase solidified at normal temperature will be solidified, resulting in rapid solidification and waste. Of course, you can also add doses of A or B, but you can't mix it until you cool it down.

3、try to choose low viscosity crystal glue

In the normal construction environment, choose as low viscosity resin as possible, of course, in the non-flat body treatment is another matter, this will only be another way, such as vacuum, but if it is processed on the flat surface, the material is not particularly thick, but there is no vacuum, you can use a hot hair dryer to blow off the foam after casting within an hour after the material is poured (room temperature). You can also pop the soap bubble with a needle and flatten the cast with a hairdryer.
