Thermally conductive potting adhesive, thermally conductive silicone grease has been applied to electronic products more glue, not only can efficiently dissipate heat, but also waterproof and moisture-proof, good insulation, in the protection of these thermally conductive materials first, can improve the stability of electronic products, efficiency and life.
Thermally conductive potting adhesive is suitable for a variety of work in harsh environments and high-end precision/sensitive electronic devices. Automotive electronics, modules, LED power drive module, solar module junction box, electric vehicle charging column module, lithium battery pack, capacitor pack, magnetic coil, inverter power supply, not only to enhance the waterproof ability of electronic products, seismic capacity and heat dissipation performance, but also to protect it from the erosion of the natural environment to prolong its service life.
Electronic products with silicone thermally conductive potting adhesive high thermal conductivity solutions
Thermally conductive electronic potting compound is liquid before curing, with fluidity, the viscosity of the glue according to the performance of the product, the material, the production process varies. Thermally conductive electronic potting compound completely cured to achieve its use value, after curing can play a waterproof moisture, thermal conductivity, confidentiality, corrosion prevention, dust, insulation, temperature resistance, shockproof role. Then apply to electronic components on the electronic potting compound need to meet what performance requirements?
1. the colloid on electronic components without any corrosive effect;
2. after curing, even after mechanical processing, the gel will not be deformed;
3. strong resistance to hot and cold changes, even if subjected to -60 ℃ ~ 200 ℃ between the hot and cold changes, the gel can still maintain the elasticity, no cracking;
4. electronic potting silicone rubber can be cured at room temperature can also be heated curing;
5. has excellent thermal conductivity, potting can effectively improve the heat dissipation of electronic products; especially now requires high thermal conductivity products to 2.0-3.0W/m.k
6. has excellent weather resistance and salt spray resistance, to ensure that electronic components are not subject to the erosion of the natural environment;
7. strong electrical insulation ability, potting can effectively improve the insulation between the internal components as well as lines;
8. electronic potting silicone rubber has water-repellent properties, potting can improve the moisture-proof performance of electronic components.
Potting of electronic products will generally use silicone material potting compound, silicone potting compound can be added to some functional fillers to give its conductive thermal conductivity and magnetic properties. Silicone encapsulant mechanical strength is generally poor, it is borrowed from this performance, so that it can achieve "can be broken open" for easy maintenance, that is, if a component failure, only need to pry open the encapsulant, replaced with a new original, you can continue to use.
