Simple Application Instructions

1. Clean: Hold the can upright 25 to 30 cm from the gasket area to be sprayed.
2. Apply: Spray a heavy coat over the area to be stripped; a heavier coat will provide better performance and foaming action.
3. Assemble: Allow 5 to 10 minutes for the foaming action to destroy the old gasket, then remove it with a scraper or putty knife. Wipe the flange clean with a rag and prep the surface with a suitable cleaner like Loctite 7070 before introducing a new gasket. *After use, turn the can upside down and spray for 3 seconds to clear the actuator.*

Frequently Asked Questions (FAQ)

What is Loctite SF 790 used for?

Loctite SF 790 is a powerful liquid solvent spray designed for the removal of baked-on chemical gaskets, gasket cements, and conventional gasket materials from metal surfaces. It is specifically formulated to prevent machine surface damage from aggressive manual scraping due to baked-on chemical residues.

Can Loctite SF 790 be used safely on all systems?

No. This product is not recommended for use in pure oxygen and/or oxygen-rich systems and should not be selected as a sealant/cleaner for chlorine or other strong oxidizing materials. Please consult the Safety Data Sheet (SDS) for comprehensive safe handling instructions.

Does Loctite SF 790 work on aluminum?

Yes. Loctite SF 790 offers robust performance across various metals. It is highly effective on delicate aluminum components, dissolving old gaskets cleanly without requiring intense manual scraping that could scratch or gouge the soft metal machine surfaces.

Is Loctite SF 790 safe for non-metal surfaces?

Yes, it is highly effective at removing paint and varnish from wood surfaces, making it excellent for removing surface coatings from delicate or carved wood without scraping. Always test on a small area first when dealing with non-metal substrates.
