A two part low cost addition cured silicone. This silicone system is designed for applications that require low stress and excellent electrical properties. Is designed for potting and encapsulation where low cost and low viscosity is required. Has an easy to use 1:1 mix ratio by weight or volume. Can be room temperature cured or heat cured. The addition of heat will greatly accelerate the cure. Can be used in temperature extremes of -40°C to 200°C. HV400, as with all addition cured silicones, has no exotherm and very low shrinkage upon cure. During cure, will not evolve any by products. Also, they will not depolymerize as many condensation cured silicones are prone to do. This easy to use formulation can be customized to address your particular and unique applications.
