The appearance of bubbles on the surface of the potting compound, the wrinkling of the surface, and the oil on the surface are all appearance problems. So why do these appearance problems occur in the potting compound, and how to eliminate the bubbles?
The influencing factors of the sedimentation phenomenon of the potting glue are mainly reflected in the uneven production and stirring, the improper storage of the powder, the serious moisture absorption, the high storage environment temperature, and the poor compatibility of the oil and powder.
In the process of potting adhesive application, most users have a defoaming process. The purpose is to ensure that there are no air bubbles and pores inside and on the surface of the colloid after the product is cured, so as not to affect the performance of the product. You may think that defoaming is a very simple operation. Open the vacuum box and pump it.
The humidity, thickness and properties of sizing will affect the deep curing of silicone adhesive
Uneven stirring before use, high low molecular content in raw materials and high oil separation rate are the three main reasons for the cracking of thermally conductive silicone grease.
Thermal grease and thermal pads are widely used in various heat-generating electronic components. For the application, operation and performance of thermal grease and thermal pads, a comprehensive analysis is required to obtain suitable adhesives. solution.
