Potting glue is no stranger to us, because we will use various glues in our lives or work. Potting glue can be used in the construction industry, but today we are going to talk about potting glue used in the electronics industry.

TIMs (Thermal Interface Materials) are designed to conform to surface irregularities, eliminate air gaps, and improve heat flow. Thermal conductive sealant is one of the categories of TIM that provides a combination of low thermal resistance and high bond strength. Using this process, heat energy is passed through a solid, liquid or gas from molecule to molecule in a material. Improving the heat flow is important because greater the temperature difference, the faster the heat flows to the colder area.

Thermal conductive silicone grease is commonly known as thermal paste, thermal conductive silicone grease is made of organosilicone as the main raw material, adding materials with excellent heat resistance and thermal conductivity to make a thermally conductive organosilicone grease-like compound.

This is the main way to select electronic potting adhesives, out of concern for fire retardancy, adhesion, water resistance and curing speed and other properties, but also should pay attention to the thermal conductivity of the adhesive and service life. Do not necessarily put the price on the important position, pay more attention to the performance of various properties. Strive to elect a good value for money adhesive for long-term use. ​

The advantage of thermally conductive adhesives for mounting LED chip heat sinks is that they provide mechanical and thermal performance over the entire area of the bond, so that heat dissipation is very effective. The maximum temperature is about 66°C. For every 1°C increase in operating temperature, the service life is significantly reduced.

1. The problem of slurry outflow when sizing is stopped Cause analysis: usually hand pressure glue gun is through the glue guns to pressure, the driveshaft forward and make the mucilage out to complete the construction process, it is to choose a thin bottle series of products, so in the process of the glue bottle can produce certain expansion, due to stress, such as in use process, if only to stop on the pressure of the glue guns, thin bottle by the recovery of expansion and contraction of the original, plus glue guns "drive shaft" inertia and thrust forward, even if the glue gun to stop pressure, cement glue will continue to drain, so can bring inconvenience to be subcontracted, more will affect construction quality.
