The thermal conductive potting adhesive is a kind of potting adhesive, the obvious feature is that it can be used in the power supply with high requirements for heat dissipation and can play a protective role. The thermally conductive potting adhesive is a shrinkable potting adhesive, which does not exothermic, solvent, and by-products in the curing process, so it can be used in various electrical and electronic fields.
What does a thermally conductive potting adhesive look like after curing?
There is no big difference between thermal conductive potting adhesive and ordinary potting adhesive after curing, a glossy film is formed on the surface, and the gel is soft when touched by hand. Construction phase adhesion is very strong, after curing anti-shock, anti-leakage protection, chemical corrosion resistance is good.
What happened to the poor impact resistance after curing the thermally conductive potting adhesive?
1, thermal conductive potting adhesive after curing performance of poor impact resistance, as long as the raw materials, if the raw materials added too much filler, this type of adhesive will force the impact resistance after curing performance is poor, the bonding strength decreased.
2, some thermal conductive potting adhesive poor impact resistance performance, mainly because the curing agent composition is subject to change, the curing agent composition contains more anti-aging performance ingredients raw materials, after curing will not affect the adhesive bonding strength, but after using a period the impact resistance performance will decline, the manufacturing cost of such adhesives is relatively low.
The thermally conductive potting adhesive is a potting adhesive widely used in the electrical manufacturing industry, this potting adhesive low viscosity, good fluidity in the process of use, good quality products after curing can achieve good impact resistance and leakage resistance, resistance to chemical media performance, as long as the mixing ratio by the science of deployment, construction can guarantee good performance.
