Does epoxy potting glue leak electricity?

Some people will want AB glue as a way to protect the circuit board, so they will want to know whether AB glue will be conductive leakage and so on. In fact, this is not leakage, ab glue can be made by adjusting the proportion of potting glue, which is used to protect the circuit board.



Introduction of potting glue
Potting adhesive, used for bonding, sealing, potting and coating protection of electronic components. Potting glue is liquid and has fluidity before it is cured. The viscosity of the glue is different according to the material, performance and production process of the product. Only after the potting glue is completely cured can its use value be realized. After curing, it can play the role of waterproof, moisture-proof, dustproof, insulation, heat conduction, secrecy, corrosion resistance, temperature resistance and shock resistance. There are many types of electronic potting adhesives, divided from the type of material, the most common use is mainly 3 kinds, that is, epoxy resin potting adhesives, silicone resin potting adhesives, polyurethane potting adhesives, and these three materials can be subdivided into hundreds of different products. Potting is an important application field of polyurethane resin. It has been widely used in the electronic device manufacturing industry and is an indispensable important insulating material in the electronic industry.

Second, the material of potting glue
Potting adhesive materials can be divided into:
Epoxy resin potting adhesive: single component epoxy resin potting adhesive; Two-component epoxy potting adhesive
Silicone rubber potting adhesive: room temperature vulcanized silicone rubber; Two-component silicone rubber potting adhesive; Two component condensation type silicone rubber potting
Polyurethane potting adhesive: two-component polyurethane potting adhesive
UV potting adhesive: UV light curing potting adhesive
Hot melt potting adhesive: EVA hot melt adhesive

Third, summarize whether AB glue conducts electricity and leaks
Epoxy AB glue can also be used as potting glue, so it will not be conductive and leakage, which can be assured.
