SI 6230 ( 40# ) silicone thermally conductive potting compound


Product features and applications

SI 6230 ( 40# ) is a two-component silicone thermally conductive potting compound with excellent flowability after mixing. Its working time can be adjusted according to temperature, and it can cure deeply at room temperature. It is suitable for potting and protecting various heat-dissipating and heat-resistant components and fully complies with EU RoHS and SVHC REACH requirements . Its basic characteristics include:


l Two-component addition-curing silicone rubber

l 1:1 mixing ratio

l Low hardening shrinkage

l Excellent high-temperature electrical insulation and stability

l Good waterproof and moisture-proof properties

       

Application areas:

l Automotive electronics, modules

l LED power driver module

l Solar module junction box

l Electric vehicle charging station module

l lithium battery pack, capacitor pack

l Magnetic coil

l Inverter power supply
