Loctite 515 Gasket Maker / Flange Sealant for Automotive, 50 ml
- Gasketing product for machined metal flanges. Medium strength. 30 min fixture time. Can also fill gaps up to 0.25 mm.
- LOCTITE 515 is a medium strength (6 N/mm² tensile shear strength), medium cure speed, methacrylate-based industrial gasketing product designed for machined, rigid metal flanges. The product, which cures anaerobically, is suitable for gaps up to 0.25 mm. It is used typically as a form-in-place product for pumps, thermostats, compressors, transmission housings and axle covers.

- How To
- Apply LOCTITE SF 790 to old gasket or gasket sealants and use a wood or plastic scraper to remove residues from flange surfaces. Remove burrs. It is recommended to use LOCTITE SF 7070 to degrease and clean surfaces prior to applying the sealant.
- If cure speed of LOCTITE 515 is too slow due to passive metals or low temperature (below 5°C), use LOCTITE SF 7649 activator. Allow to dry.
- Apply a continuous bead of sealant onto one flange surface. Place the bead close to the inner rim of the flange and encircle all bolt holes. Small surface scratches will be filled by the adhesive. LOCTITE 515 can also be applied by roller onto larger flanges.
- Assemble flanges and tighten bolts as soon as possible. Wipe away any excess squeeze-out, as this will not cure when exposed to air due to the sealant's anaerobic curing properties.
- Disassemble bolts with standard hand tools. Use jacking-screws, cast-on bosses or recesses to lift flanges apart. Once disassembled, apply LOCTITE SF 790 on old sealant and use a wood or plastic scraper to remove residues from flange surfaces.
