CHT SilSo SE2014 Silicone elastomer
Categories:	Polymer; Thermoset; Silicone
Material Notes:	Description: This is a 2-component, silicone elastomer system specially designed for electronic potting and encapsulation applications. It offers good protection against chemicals, environmental contamination, mechanical shock, vibration and impact damage. It can be employed in areas where low flammability is a prerequisite. The cured elastomer can be repaired. The component parts have relatively low viscosities and are readily mixed either by hand or machine. Key Features Light weight and low density Long pot life UL recognized in file number E334038 Very high dielectric strength Application: Coating for the umbilical cable ROV underwater remotely operated vehicles Information provided by CHT Group
