The construction of two-component silicone potting adhesive is more complicated and not as convenient as single-component products. There are certain requirements for the construction personnel. Because the construction of two-component silicone potting adhesive needs to go through weighing, mixing, mixing, glue injection, waiting for curing several links. So, silicone potting adhesive construction, why should be mixed evenly?
A and B components are weighed and mixed in proportion, and the two components need to be stirred separately to make the settled filler strip evenly dispersed in the glue. Then put the B component into the A component and mix it again, and pay attention to not bringing in air when mixing.
If the mixing is done without full stirring of A and B components after weighing, it will easily lead to the settling filler not being fully dispersed in the glue, and at this time the mixed glue is not uniform within the glue because the filler is not uniform, and the cured material will easily appear after curing with bad effects. Curing material in the curing process of the precipitation can not be fully dispersed in the glue, although it will not affect the hardness, in appearance looks and normal construction of the glue no difference, but such a glue is easy to appear in the upper and lower layers of curing material is not uniform, the overall performance will be affected.
Many times factories do not pay attention to the mixing of silicone potting adhesive, perfunctory, which is also a major cause of unstable performance after curing. And such products are difficult to find immediately, only some of the use of potting products in use for a period of time before gradually manifesting the lack of performance.
