Loctite 620 Retaining Compound Instruction Manual

1. 서론

The Loctite 620 Retaining Compound is a high-strength, high-temperature anaerobic adhesive designed for bonding cylindrical fitting parts. This product is formulated to lock and secure metal cylindrical assemblies, prevent metal fretting and corrosion, and seal against leakage. It is suitable for applications requiring high temperature resistance and robust bonding.

3. 안전 정보

Always prioritize safety when handling chemical products. Consult the Material Safety Data Sheet (MSDS) for comprehensive safety information before use. The MSDS for Loctite 620 Retaining Compound (e.g., 62015 Retaining Compound Slip Fit 620.pdf) provides detailed guidance on safe handling, storage, and emergency procedures.

• 개인 보호 장비: Wear appropriate gloves and eye protection (safety glasses or goggles) to prevent skin and eye contact.
• 통풍: 증기 흡입을 피하기 위해 환기가 잘 되는 곳에서 사용하십시오.
• 저장: 직사광선과 상충되는 물질을 피해 서늘하고 건조한 곳에 보관하십시오. 사용하지 않을 때는 용기를 꼭 닫아 두십시오.
• 응급 처치: In case of contact, refer to the MSDS for specific first aid measures.
• 처분: Dispose of product and packaging in accordance with local, regional, national, and international regulations.
• 손이 닿지 않는 곳에 보관하세요: 어린이와 애완동물의 손이 닿지 않는 곳에 보관하세요.

4. 설치 및 표면 준비

Proper surface preparation is critical for optimal performance of the retaining compound.

1. 깨끗한 표면: Thoroughly clean all mating surfaces to remove any oil, grease, dirt, or other contaminants. Use a suitable industrial cleaner or degreaser.
2. 건조한 표면: Ensure all surfaces are completely dry before applying the compound. Moisture can interfere with the curing process.
3. Roughening (Optional): For maximum adhesion on passive metals or large gaps, light abrasion of the surfaces may be beneficial, followed by cleaning.

5. 사용 설명서(응용 프로그램)

Follow these steps for effective application of Loctite 620 Retaining Compound:

1. Dispense Compound: Apply a sufficient amount of Loctite 620 Retaining Compound to one or both mating surfaces of the cylindrical assembly. Ensure complete coverage of the bond area.
2. 부품 조립: Quickly assemble the parts. The anaerobic curing process begins when the compound is confined between the metal surfaces in the absence of air.
3. 경화 시간:
   • Fix Cure Time: Approximately 30 hours at 77°F (25°C). This is the time required for the assembly to achieve sufficient handling strength.
   • 완전 경화 시간: Approximately 24 hours at 77°F (25°C). This is the time required for the product to achieve its maximum strength. Note: Cure times can vary depending on temperature, gap, and substrate material.
4. 조립 후: Avoid disturbing the assembly during the initial fix cure period to ensure proper bonding.

6. 유지 관리 및 보관

Proper storage ensures the longevity and effectiveness of the product.

• 보관 조건: Store the Loctite 620 Retaining Compound in its original container in a cool, dry, and well-ventilated area. Ideal storage temperature is between 46°F (8°C) and 82°F (28°C).
• 용기 밀봉: Keep the bottle tightly closed when not in use to prevent air exposure, which can initiate curing.
• 유통기한: Refer to the product packaging or technical data sheet for specific shelf life information.

7. 문제 해결

If you encounter issues during application or curing, consider the following:

• No Cure or Slow Cure:
  • 표면 청결도: Ensure surfaces were thoroughly cleaned and degreased. Contaminants can inhibit curing.
  • Anaerobic Conditions: Verify that the compound is fully confined between metal surfaces with minimal air exposure. Anaerobic adhesives require the absence of air to cure.
  • 온도: Curing speed is temperature-dependent. Lower temperatures will result in slower cure times. Ensure application is within recommended temperature ranges.
  • 기판 재료: Some metals (e.g., stainless steel, zinc, aluminum) are less active and may cure slower. An activator may be required for passive substrates or large gaps, though not explicitly mentioned for this product, it's a general anaerobic adhesive troubleshooting step.
• 접착력 저하:
  • Gap Size: Ensure the gap between parts is within the specified 0.015-inch maximum. Excessive gaps can lead to incomplete curing and poor strength.
  • 표면 준비: Re-evaluate surface cleaning and drying procedures.
