Customer Questions & Answers

Question: What is Loctite 620 Retaining Compound used for?

Answer: Loctite 620 is a high-temperature retaining compound used to secure and bond cylindrical metal assemblies. It is particularly effective in applications involving high heat and stress, such as motors, pumps, and other machinery components. The compound fills gaps and creates a strong bond that resists disassembly under thermal expansion or vibration. Using Loctite 620 in your repair or assembly work can greatly enhance the durability and reliability of your machinery.
Question: What materials does Loctite 620 adhere to?

Answer: Loctite 620 effectively adheres to metals, including steel, stainless steel, and aluminum. Its formulation is designed to create strong bonds even in the presence of oil or machining fluids, making it ideal for automotive and industrial applications. This capability ensures robust and lasting connections in various engineering settings, which is essential when working with equipment that operates under high temperatures or pressures.
Question: How do you apply Loctite 620 for optimal results?

Answer: For the best results with Loctite 620, clean the surfaces to be bonded and ensure they are free from debris and contaminants. Apply the compound evenly on one of the surfaces, then assemble the parts and allow it to cure. The curing time can vary but usually requires several hours to reach maximum bond strength. This application process is crucial in achieving a solid and durable bond, especially in high-stress environments.
Question: What is the curing time for Loctite 620?

Answer: Loctite 620 typically has a curing time of approximately 24 hours for full strength. However, it can start to set in about 10 to 20 minutes after application. The actual cure can be affected by factors such as temperature and the materials used. For optimal performance, it’s advisable to allow the product to cure undisturbed, especially in critical applications where durability is paramount.
Question: Is Loctite 620 resistant to chemicals?

Answer: Yes, Loctite 620 is resistant to a wide range of chemicals, which makes it suited for use in environments exposed to oils, fuels, and other harsh substances. Its chemical resistance helps maintain integrity and performance without degradation over time, thus ensuring reliability in automotive, aerospace, and manufacturing applications. This resistance contributes significantly to its effectiveness in maintaining joints subject to operational challenges.
Question: Can Loctite 620 be used for repairing threaded fasteners?

Answer: Loctite 620 can be used to secure threaded fasteners that are subjected to high temperature and vibration. However, it is specifically formulated for cylindrical fittings rather than threaded connections. For threaded applications, consider using Loctite products that are specifically designed for that purpose, as they provide better sealing and locking characteristics for screws and bolts. This targeted approach ensures your repairs are both effective and appropriate.
Question: What safety precautions should be taken when using Loctite 620?

Answer: When using Loctite 620, it's important to work in a well-ventilated area to avoid inhaling fumes. Use gloves to prevent skin contact, and ensure eye protection if there is a risk of splashing. If any product inadvertently makes contact with skin or eyes, wash thoroughly with soap and water or rinse with plenty of water. Following safety guidelines ensures a safe working environment while handling adhesive products.
Question: How does Loctite 620 compare to other retaining compounds?

Answer: Loctite 620 stands out in the market for high-temperature applications due to its excellent thermal resistance and strong adhesive properties. Compared to other retaining compounds, it is specifically designed to withstand extreme conditions, making it ideal for heavy-duty industrial machinery. Additionally, its formulation helps to prevent loosening due to thermal cycling or vibration, ensuring longevity and performance in critical applications.
Question: Can I use Loctite 620 on plastics or rubber?

Answer: Loctite 620 is designed primarily for metal applications and may not bond effectively to plastics or rubber materials. For those types of substrates, it’s advisable to use a specialized adhesive designed for plastics or rubber, ensuring the most effective bonding. Choosing the right product for your specific material is crucial to achieve the desired results and maintain the integrity of your assemblies.
Question: Where can I buy Loctite 620 442-62040 50ml Retaining Compound in New Zealand?
