Loctite SF 7471 Primer, 4.5 oz Aerosol

LOCTITE SF 7471 is an acetone-based primer designed to accelerate the cure of LOCTITE anaerobic adhesives and sealants. This 4.5 oz aerosol is particularly useful when working with passive or inactive metal surfaces, larger bond gaps, or applications where cure conditions are below 15°C (59°F).

LOCTITE SF 7471 helps improve cure speed when used with compatible anaerobic threadlockers, retaining compounds, and sealants. The aerosol format provides convenient application to the required bonding surfaces before applying the anaerobic adhesive.

LOCTITE SF 7471 Features

• Acetone-based primer and activator for LOCTITE anaerobic adhesives and sealants
• Helps accelerate cure on passive and inactive metal surfaces
• Useful for applications involving large bond gaps
• Recommended for low-temperature cure conditions below 15°C (59°F)
• 4.5 oz net weight aerosol can
• Transparent yellow-to-amber liquid
• Very low viscosity for easy surface application

Applications

LOCTITE SF 7471 is used to accelerate the cure of compatible LOCTITE anaerobic products when additional activation is needed. It is particularly suited to passive or inactive metal surfaces and applications involving larger bond gaps. Henkel also recommends SF 7471 when prevailing temperatures are below 15°C (59°F).

Typical applications include use with anaerobic threadlockers, retaining compounds, and sealants when faster or more reliable curing is required under challenging surface or temperature conditions.

How to Use LOCTITE SF 7471

Apply LOCTITE SF 7471 to the appropriate surface before applying the compatible anaerobic adhesive or sealant. Allow the activator to dry according to the manufacturer's instructions before proceeding with adhesive application.

The resulting fixture and cure speed depends on the specific anaerobic product being used and the substrates involved. Always consult the applicable LOCTITE Technical Data Sheet (TDS) for detailed surface preparation and application instructions.

LOCTITE SF 7471 for Maintenance and MRO

LOCTITE SF 7471 can be useful in maintenance and MRO environments where anaerobic adhesives must cure reliably on passive metal surfaces or under low-temperature conditions. Its aerosol packaging provides a convenient format for treating surfaces before application of compatible LOCTITE anaerobic products.

Important: SF 7471 is a flammable solvent-based product. Use only in accordance with the manufacturer's safety instructions and applicable workplace requirements. Refer to the current manufacturer's TDS and SDS for complete handling, compatibility, ventilation, storage, and safety information.
