Grey Black Electricalsilicone Potting Compound For Electronics Waterproof Thermal Potting Silicone For Connector PCB Cable
Product description:
Silicone potting compound is an electronic encapsulation material primarily made of silicone rubber. It is used to protect electronic components and provides waterproofing, moisture resistance, insulation, and shock resistance. After curing, it forms an elastomer that remains stable over a wide temperature range and exhibits good thermal conductivity and electrical properties.
