Loctite Activator Spray SF 7471

Loctite SF 7471 is a general-purpose activator designed to accelerate the curing process of anaerobic adhesives and sealants. It is especially useful in applications where bond strength and fast curing are critical, and where environmental conditions may slow down the curing process.

Key Features

1. Cure Acceleration:
   • Speeds up the curing process of anaerobic adhesives and sealants.
2. Wide Compatibility:
   • Works with all Loctite anaerobic products, including threadlockers, retainers, and flange sealants.
3. Low Toxicity:
   • Formulated to minimize health and safety concerns.
4. Fast-Drying Formula:
   • Dries quickly, allowing for efficient assembly processes.
5. Versatile Application:
   • Suitable for both passive and active metal surfaces.

Applications

• Threadlocking: Enhances curing of threadlockers on inert materials.
• Flange Sealing: Promotes faster curing of sealants in low-temperature or inactive metal applications.
• Retaining Applications: Ideal for bonding cylindrical parts, such as bearings and bushings.
• Inert Substrates: Activates surfaces like stainless steel, zinc, or anodized aluminum.

Technical Specifications

• Base: Solvent-based
• Color: Clear/Amber
• Application Method: Spray
• Drying Time: 30–70 seconds (depending on ambient conditions)
• Operating Temperature: -20°C to +120°C (-4°F to +248°F)

How to Use

1. Preparation:
   • Ensure the bonding surfaces are clean, dry, and free of grease or contaminants.
2. Application of Activator:
   • Spray a thin, even layer of Loctite SF 7471 onto one or both surfaces.
   • Allow the activator to dry for 30–70 seconds.
3. Adhesive Application:
   • Apply the anaerobic adhesive or sealant to the bonding area as per product instructions.
4. Assembly:
   • Join the parts immediately after applying the adhesive.
5. Curing:
   • The activator will enhance the curing speed, even on inert materials or in low-temperature conditions.

Advantages

• Enables faster curing in challenging environments.
• Reduces downtime in assembly and maintenance processes.
• Improves bond strength on passive or inactive substrates.
• Suitable for low-temperature applications.

Storage

• Store in a cool, dry place away from direct sunlight and heat sources.
• Keep the container tightly closed when not in use.

Safety Precautions

• Use in a well-ventilated area.
• Avoid inhalation and contact with skin or eyes.
• In case of contact, rinse thoroughly with water.
• Refer to the Safety Data Sheet (SDS) for detailed handling and disposal instructions.

Loctite SF 7471 Activator Spray ensures optimal performance and reliability of anaerobic adhesives and sealants, even under challenging conditions.
