LOCTITE 2892

LOCTITE 2892 is a one-component, blue, high-viscosity anaerobic methacrylate sealant for form-in-place sealing between rigid metal flanges. It fills surface imperfections and has a stated gap-filling capability up to 0.254 mm, while application directions specify close-fitting flange gaps up to 0.1 mm. Brookfield viscosity is 2,500,000 to 4,600,000 mPa s at 0.5 rpm and 450,000 to 950,000 mPa s at 5 rpm, both at 25 deg C. After cure between mating flanges, it forms a tough, resilient seal that flexes with movement from vibration, pressurization, or thermal changes. Application methods include a continuous manual bead or screen printing.

Key features

• Close-flange gap filling: Gap-filling capability extends to 0.254 mm, while application directions specify close-fitting flanges with gaps up to 0.1 mm.
• High-viscosity rheology: Brookfield viscosity spans 2,500,000 to 4,600,000 mPa s at 0.5 rpm and 450,000 to 950,000 mPa s at 5 rpm.
• Resilient cured seal: The cured material flexes with flange movement caused by vibration, pressurization, or thermal changes.

Applications

Applications include form-in-place sealing of close-fitting rigid metal flanges by continuous manual bead or screen printing.
