Loctite 222 Low Strength Threadlocking Adhesive Instruction Manual

1. 제품 오버view

Loctite 222 is a low-strength, thixotropic, methacrylate-based threadlocking adhesive designed for locking and sealing threaded fasteners that require easy disassembly with standard hand tools. This product prevents loosening and leakage from shock and vibration by filling all gaps between mating threads. It is suitable for all metal threaded assemblies, including passive substrates like stainless steel, aluminum, and plated surfaces. Loctite 222 is characterized by its purple color and fluoresces under UV light, aiding in product detection during service.

• Outperform Locking Devices: Provides superior locking compared to mechanical locking methods.
• Increase End Product Service Life: Contributes to the longevity of the final product.
• Prevent Galling and Corrosion: Protects threads from wear and environmental degradation.
• Save Cost: Reduces expenses associated with maintenance and part replacement.
• Minimize Inventory Cost and Complexity: Simplifies inventory management by reducing the need for various locking hardware.
• Allow for Disassembly: Enables easy removal of fasteners using standard hand tools, crucial for maintenance and repair.
• Excellent Chemical and Thermal Resistance: Maintains performance under various chemical exposures and temperature fluctuations.

3. 설정 및 준비

1. 깨끗한 표면: For best results, clean all threaded surfaces (both bolt and nut) with a suitable cleaning solvent, such as Loctite SF 7063, and allow to dry.
2. 표면 상태: Loctite 222 is designed to tolerate minor surface contamination from industrial oils (e.g., motor oils, corrosion prevention oils, cutting fluids). However, excessive contamination should be removed.
3. 입문서 (선택 사항): If cure speed is too slow, or if working with inactive metals or large gap sizes, consider using an activator like Loctite SF 7649 or Loctite SF 7471. Consult the product's technical data sheet for specific recommendations.
4. 온도: Apply the product at room temperature (20-25°C / 68-77°F) for optimal performance.

4. Operating and Application Instructions

4.1. For Thru-Holes

• Apply several drops of Loctite 222 onto the bolt at the nut engagement area.
• Assemble and tighten as required.

4.2. For Blind Holes

• Apply several drops of Loctite 222 down the internal threads to the bottom of the blind hole.
• Assemble and tighten as required.

4.3. For Sealing Applications

• Apply a 360° bead of product to the leading threads of the male component, leaving the first thread free.
• Distribute the product to fill the gaps. For larger diameters and gaps, adjust product quantity accordingly.
• Assemble and tighten as required.

경화 시간: The product will fixture in approximately 10 minutes at room temperature. Full cure is achieved in 24 hours. Functional strength is typically reached sooner, allowing for handling.

5. Maintenance and Disassembly

5.1. 분해

Due to its low strength, Loctite 222 allows for easy disassembly using standard hand tools. No special heating or tools are typically required for removal.

5.2. 보관

Store Loctite 222 in its original container in a cool, dry location. Optimal storage temperature is between 8°C to 21°C (46°F to 70°F). Do not return unused product to the original container as contamination may reduce shelf life.

6. 문제 해결

• Product Not Curing:
  • Ensure surfaces are clean and free from heavy grease or oil.
  • Verify that the product is applied between metal surfaces; anaerobic adhesives cure in the absence of air and in contact with metal.
  • Consider using an activator (e.g., Loctite SF 7649) if working with inactive metals (e.g., zinc, cadmium, anodized aluminum) or if cure speed is critical.
  • Check ambient temperature; very low temperatures can slow down the cure process.
• 조제에 어려움:
  • If the nozzle is clogged, clear it with a pin or toothpick. Do not cut the nozzle opening larger than necessary.
  • Ensure the bottle is stored upright to prevent clogging.
