High-Performance Fluorosilicone Sealant Features
Our LR-FR3000 is a premium one-component RTV sealant specifically engineered for extreme environments. It provides:
-
Elite Fuel Resistance: Maintains a tight seal even when in constant contact with automotive fuels and oils.
-
Broad Temperature Stability: Reliable performance from -60°C up to +225°C.
-
Superior Adhesion: Ideal for FIPG (Formed-in-Place Gaskets) on engines and transmissions.

Application:
LR-FR3000 Series is recommended for flat-surface sealing / form-in-place sealing in:
- Engines
- Transmissions and gearboxes
- Drivetrain / powertrain components
- Brake systems
- Pipe flanges and flange joints
Package &Storage:
Net content: 300 mL plastic cartridge.
Store in a cool, dry environment. Shelf life is 6 months in the original unopened packaging. Avoid contact with eyes before curing. In case of accidental contact, rinse immediately with water and seek medical attention.
Technical Tip: For applications requiring a raw base polymer instead of a finished sealant, explore our LF-HF11 Hydroxyl Fluorosilicone Fluid which offers excellent anti-structuring properties.
