Loctite 277 Threadlocker 50ml

LOCTITE SF 7471 Primer T is a fast-acting surface activator designed to accelerate the curing of LOCTITE anaerobic adhesives and sealants. Ideal for stainless steel, aluminium, plated metals and other passive surfaces, it helps reduce fixture time and improve assembly efficiency.

Also known as LOCTITE 7471 Activator, this solvent-based primer is especially useful for applications involving large bond gaps, inactive metals or low temperatures below 15°C.

Key Features & Benefits

• Faster Adhesive Curing: Accelerates the cure of compatible LOCTITE anaerobic threadlockers, retaining compounds, thread sealants and gasketing products.

• Ideal for Passive Metals: Helps promote curing on stainless steel, aluminium, plated components and other inactive surfaces.

• Suitable for Large Bond Gaps: Supports more effective curing where increased clearances slow down anaerobic adhesive reactions.

• Low-Temperature Performance: Particularly recommended for assembly conditions below 15°C.

• Up to 7 Days On-Part Life: Treated components can be stored for up to 7 days before bonding, provided surfaces remain clean and uncontaminated.

• Fast Solvent Evaporation: Typical drying time of 30–70 seconds at 20°C, allowing efficient surface preparation.

Common Industrial Applications

LOCTITE SF 7471 is widely suitable for use in:

• Precision Engineering: Threadlocking and retaining applications involving stainless steel and plated metal components.

• Machinery Assembly: Faster adhesive curing on fasteners, bushings, bearings and mechanical fittings.

• Industrial Maintenance & Repair: Accelerating the cure of anaerobic adhesives during machinery servicing and equipment repair.

• Metal Fabrication: Surface activation for metal assemblies where conventional anaerobic curing is slow.

• Manufacturing Production Lines: Supporting shorter assembly waiting times and improved production throughput.

Technical Specifications

How to Apply LOCTITE SF 7471

1. Clean the Surfaces: Remove oil, grease, dirt and contaminants from the components.

2. Apply the Activator: Spray or brush onto the mating surfaces, depending on the product packaging. For small bond gaps, treating one surface may be sufficient.

3. Allow to Dry: Let the solvent evaporate completely in a well-ventilated area before applying adhesive.

4. Apply LOCTITE Adhesive: Apply a suitable anaerobic threadlocker, retaining compound or sealant and assemble immediately.

5. Allow to Fixture: Secure the assembly and allow sufficient curing time before handling or loading.

Important: Never mix the liquid activator directly with liquid adhesive. This product is highly flammable. Always follow the product Safety Data Sheet.

Frequently Asked Questions

What is LOCTITE SF 7471 used for?

LOCTITE SF 7471 is used to speed up the curing of anaerobic adhesives and sealants, particularly on inactive metal surfaces, with large bond gaps or at low temperatures.

Is LOCTITE 7471 suitable for stainless steel?

Yes. Stainless steel is a passive metal that can slow down anaerobic adhesive curing. Applying SF 7471 helps accelerate the curing process.

Can LOCTITE SF 7471 be used with threadlockers?

Yes. SF 7471 is designed for compatible LOCTITE anaerobic products, including threadlockers, retaining compounds, thread sealants and gasketing adhesives.

How long does LOCTITE SF 7471 take to dry?

Typical drying time is approximately 30–70 seconds at 20°C. Actual drying time depends on temperature, application quantity and ventilation.

What is the difference between LOCTITE SF 7471 and SF 7649?

Both are activators designed to accelerate anaerobic adhesive curing. However, they differ in formulation and on-part life. SF 7471 provides up to 7 days of on-part life, while SF 7649 provides up to 30 days.

Where can I buy LOCTITE SF 7471 in Singapore?
