3. ข้อมูลด้านความปลอดภัย

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.

• อุปกรณ์ป้องกันภัยส่วนบุคคล: Wear appropriate gloves and eye protection (safety glasses or goggles) to prevent skin and eye contact.
• การระบายอากาศ : ควรใช้ในบริเวณที่มีอากาศถ่ายเทสะดวก เพื่อหลีกเลี่ยงการสูดดมไอระเหย
• พื้นที่จัดเก็บ: Store in a cool, dry place, away from direct sunlight and incompatible materials. Keep container tightly closed when not in use.
• ปฐมพยาบาล: In case of contact, refer to the MSDS for specific first aid measures.
• การกำจัด: Dispose of product and packaging in accordance with local, regional, national, and international regulations.
• เก็บให้พ้นมือเข้าถึง: เก็บให้พ้นจากมือเด็กและสัตว์เลี้ยง

4. Setup and Surface Preparation

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

1. พื้นผิวที่สะอาด: Thoroughly clean all mating surfaces to remove any oil, grease, dirt, or other contaminants. Use a suitable industrial cleaner or degreaser.
2. พื้นผิวแห้ง: 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. คู่มือการใช้งาน (แอปพลิเคชัน)

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. ประกอบชิ้นส่วน: Quickly assemble the parts. The anaerobic curing process begins when the compound is confined between the metal surfaces in the absence of air.
3. เวลาในการบ่ม:
   • Fix Cure Time: Approximately 30 hours at 77°F (25°C). This is the time required for the assembly to achieve sufficient handling strength.
   • เวลารักษาเต็ม: 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. หลังการประกอบ: Avoid disturbing the assembly during the initial fix cure period to ensure proper bonding.

6. การบำรุงรักษาและการจัดเก็บ

Proper storage ensures the longevity and effectiveness of the product.

• เงื่อนไขการจัดเก็บ: 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).
• Container Sealing: Keep the bottle tightly closed when not in use to prevent air exposure, which can initiate curing.
• อายุการเก็บรักษา: Refer to the product packaging or technical data sheet for specific shelf life information.

7 การแก้ไขปัญหา

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

• No Cure or Slow Cure:
  • ความสะอาดพื้นผิว: 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.
  • อุณหภูมิ: Curing speed is temperature-dependent. Lower temperatures will result in slower cure times. Ensure application is within recommended temperature ranges.
  • วัสดุพื้นผิว: 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.
• การยึดเกาะที่ไม่ดี:
  • 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.
  • การเตรียมพื้นผิว: Re-evaluate surface cleaning and drying procedures.
