Silicone Potting Compound For Electronics 1:1 Grey RTV Silicone Potting Material Flexible Potting Compound
Product Overview for silicone potting compound:
Silicone potting compound is an electronic encapsulation material based on silicone polymers. It is primarily applied by pouring a liquid two-component (or single-component) mixture into electronic components, where, upon curing, it forms an elastic, three-dimensional network structure.

Product Applications for silicone potting compound:
The latest silicone potting compounds primarily focus on the precision encapsulation and thermal management of new energy vehicles (specifically the "three-electric" systems and battery packs), third-generation semiconductors (such as IGBT and SiC modules), and 5G communication equipment; core technological developments are centered on "high thermal conductivity," "lightweight foaming," and "vibration resistance across extreme low and high temperatures."
Packaging & Storage for silicone potting compound:
Standard Packaging: Component A 25kg/drum, Component B 25kg/drum.
Store in a cool, dry place. Shelf life: 6 months.
