DOLPHIN 120 HIGH TEMPERATURE SILICONE SEALANT is a one-part moisture-curing RTV (Room Temperature Vulcanizing) silicone that cures to form a tough rubber. DOLPHIN 120 HIGH TEMPERATURE SILICONE SEALANT was specifically formulated to be used where operating temperatures up to 300°C (572°F) are reached intermittently. It contains red iron oxide which enables it to be a true high temperature silicone sealant that will continue to be resilient at extreme temperatures.
- Use in industrial ovens
- High temperature general sealing and waterproofing
- Automotive applications
- Water and oil pumps seals
- Wire and cable insulation
- Furnace and humidifier
- Engine components
- Telecommunications including coaxial cable connectors
The substrate areas that will be in contact with sealant must be clean, dry and free of all loose materials, dust, dirt, rust, oil and other contaminants. Non – porous substrates should be cleaned with a solvent and a clean, lint – free, cotton cloth. Wipe dry immediately with another such cloth before the solvent evaporates from the surface.
TOOLING AND FINISHING
Immediately tool sealant after application and before skin formation. Tooling of sealant should be done in one continuous stroke. Remove masking tape immediately after tooling is completed.
CLEANUP AND REMOVAL
Uncured sealant may be removed from tools, equipment and non-porous surfaces with solvents. For porous substrates, allow the sealant to cure before removal by peeling or other mechanical means. Cured sealant can only be removed mechanically.
When stored in original unopened container at or below 77°F (25°C) in dry warehouse conditions, DOLPHIN 120 HIGH TEMPERATURE SILICONE SEALANT has a shelf life of 18 months from manufacturing date. Containers should always be kept sealed when not in use.
