Description
Insulcast RTVS 27Fc is a two-part RTV silicone potting and encapsulation compound for protecting electronic assemblies from heat, moisture, and vibration. It pours or pumps around the assembly and cures to a tough, protective mass that keeps the finished part working in the field.
Insulcast RTVS 27Fc Benefits
- Seals out moisture, dust, and contaminants
- Cushions components against shock and vibration
- Thermally conductive to carry heat away from hot-running parts
- Flame retardant to UL 94 V0 for fire-safety requirements
- Strong dielectric protection for reliable electrical isolation
- Backed by ITW Performance Polymers
Common Applications
- Potting power supplies, transformers, and coils
- Sealing sensors, connectors, and control modules
- Protecting LED and lighting electronics
- Encapsulating medical device electronics
- EV and e-mobility power electronics
Typical Properties
- Two-component RTV silicone system (Part A and Part B)
- Thermally conductive formulation
- Flame retardant, UL 94 V0 rated
- Strong dielectric strength for electrical isolation
- Numeric mix ratio, viscosity, pot life, cure, hardness, and service temperature are published on the product data sheet
Surface Prep and Use
Mix Part A and Part B at the ratio shown on the product data sheet. Pour or pump the mixed compound around the assembly and degas under vacuum for a void-free pot in critical work. Allow the compound to cure per the data sheet before returning the part to service.
