RTV6428 A/B silicone rubber compound is a very fast curing, two-component, low viscosity, RTV silicone material and an excellent candidate to consider for junction box potting applications. It can help provide protection of electronic components and assemblies against thermal shock, vibration, moisture, ozone, dust, many types of chemicals, and other environmental hazards. It typically has outstanding dielectric and flammability properties.
RTV6428 A/B silicone rubber compound can offer an extremely fast cure time either at room temperature or with the addition of heat. It is supplied with curing agent in matched kits which are used at a convenient 1:1 ratio by weight.
