We often encounter some problems in the process of using potting glue, such as the glue does not cure, the curing time is too long, and there are air bubbles after curing. The following will introduce to you the problems that are often encountered during the use of potting glue and the reasons for the problems.
1. Dehydration does not cure, the cured resin is too soft, and the surface is too sticky
Reason: This kind of problem during the use of potting glue is generally caused by the inaccurate mixing ratio or uneven mixing of the two components.
2. The curing time is too long
Reason: If this problem occurs when the proportion is accurate and the mixing is uniform, it is very likely that the curing temperature is too low. One of the characteristics of two-component potting glue is that it is greatly affected by temperature. The higher the temperature, the lower the viscosity of the rubber compound and the faster the curing speed. On the contrary, the lower the temperature, the longer the curing time.
3. There are bubbles after curing
Reason: If bubbles are found after curing during the use of potting glue, it is usually caused by the fact that the gas has not escaped or eliminated from the liquid glue.
4. Some glues are cured, some glues are not cured or cured incompletely
Reason: If this kind of problem occurs during the use of potting glue, it is usually caused by uneven stirring,
