Henkel LOCTITE SF 790 Gasket Remover and Paint Stripper for Metal Surfaces

LOCTITE SF 790 Gasket Remover and Paint Stripper for Efficient Maintenance

Removing old gasket residue by aggressive scraping can consume time and may mark precision-machined flange faces. LOCTITE SF 790 Gasket Remover and Paint Stripper chemically softens stubborn residue so it can be lifted more efficiently with a scraper or putty knife. It is suitable for conventional pre-cut gasket materials, baked-on gasket cements, RTV silicone gaskets, and anaerobic formed-in-place gaskets on metal components.

The aerosol format supports targeted application around bolt holes, recesses, corners, grooves, and small assemblies. Because the foam does not readily run off, users can apply a heavier coating where additional stripping power is needed. The product is also useful for removing high-temperature engine paint before repair and loosening built-up carbon deposits from internal engine or combustion surfaces.

Industrial Applications for LOCTITE SF 790 Gasket Remover and Paint Stripper

Typical applications include cleaning engine blocks, cylinder heads, valve covers, gearboxes, pumps, compressors, transmissions, motor housings, industrial flanges, and maintenance components. It can also serve as a pre-cleaner for heavily baked oil and grease before final solvent washing, helping keep downstream cleaning baths cleaner for longer.

The product is intended for metal surfaces, including aluminum components where reduced scraping can help protect machined areas. Compatibility should still be verified on representative parts, coatings, plastics, rubber, painted sections, and surrounding materials before full use. Mask or remove sensitive non-metallic components that may be affected by strong solvents.

7 Key Benefits for Maintenance and Repair

• One-part aerosol product with no mixing required.
• Penetrating spray reaches intricate and difficult-to-access shapes.
• Foaming action remains on vertical surfaces with limited run-off.
• Removes baked-on gaskets, gasket cements, RTV silicone, and anaerobic sealants.
• Helps reduce heavy mechanical scraping on metal flange surfaces.
• Useful for paint, varnish, carbon, baked grease, and oil deposits.
• Supports faster surface preparation before installing a replacement gasket or sealant.

How to Use LOCTITE SF 790 Gasket Remover and Paint Stripper

Hold the aerosol can upright approximately 25 to 30 cm from the area. Spray the residue thoroughly; a heavier coating generally improves stripping performance. Allow the foaming action to work for approximately five to ten minutes. Remove the softened gasket or cement with a scraper or putty knife, then wipe the flange with a clean rag. Repeat the process when necessary.

Before installing a new gasket or applying a new sealant, clean the surface with a suitable final cleaner such as LOCTITE SF 7070 Cleaner. After use, turn the can upside down and spray for approximately three seconds to clear the actuator. Use the product only with suitable ventilation and personal protective equipment, and follow the current safety data sheet because the solvent-based aerosol requires careful handling.
