LOCTITE® 5205
Features and Benefits
A 1-part, red, medium-strength gasketing sealant for machined rigid-metal flanges where semi-flexibility is required.
LOCTITE® 5205 is a 1-part, medium strength, methacrylate-based gasketing sealant for machined, rigid metal flanges requiring semi-flexibility. It’s typically used as a form-in-place gasket for gearboxes and engine casings. This red, viscous anaerobic-curing flange sealant fills gaps up to 0.25 mm (0.01") and can be dispensed robotically. Fluoresces under UV light – great for quality control.
- Fluorescent under UV for quality control
- Suitable for gap filling (up to 0.25mm)
- Semi-flexible
