How to
Step by Step Guide
1. Preparation - Cleaning
Apply LOCTITE® SF 7200 or 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 7063 of SF 7070 to degrease and clean surfaces prior to applying the sealant.
2. Preparation - Activation
If cure speed of LOCTITE® 510 is too slow due to passive metals or low temperature (below 5°C), use LOCTITE® SF 7649 activator. Allow to dry.
3. Application
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® 510 can also be applied by roller onto larger flanges.
4. Assembly
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.
5. Disassembly
Disassemble bolts with standard hand tools. Use jacking-screws, cast-on bosses or recesses to lift flanges apart. Once disassembled, apply LOCTITE® SF 7200 or SF 790 on old sealant and use a wood or plastic scraper to remove residues from flange surfaces.
