Customer Questions & Answers

Question:
What is LOCTITE 518 Anaerobic Flange Sealant used for?
Answer: LOCTITE 518 is specifically designed for creating hermetic seals between metal flanges in automotive and industrial applications. This high-strength sealant effectively fills gaps and prevents leaks caused by vibrations or thermal expansion. It's ideal for use in engine components, pumps, and gearboxes, where a robust seal is required. When applied, it cures in the absence of air, ensuring a strong bond that withstands high pressures and temperatures. -
Question:
How does LOCTITE 518 differ from other sealants?
Answer: LOCTITE 518 offers superior performance compared to traditional sealants due to its anaerobic formulation, which cures when airtight. Unlike RTV silicones, LOCTITE 518 does not shrink over time, providing a durable and permanently flexible seal. This feature is particularly beneficial in heavy machinery where sealing under high pressure is crucial. Many users prefer it for its reliability and ease of use in critical engine applications. -
Question:
Can LOCTITE 518 be used on plastic surfaces?
Answer: LOCTITE 518 is primarily formulated for metal-to-metal applications and is not recommended for plastic surfaces. Its curing properties and adhesive strength work best with metals, ensuring a tight seal against leaks and environmental factors. For plastic applications, consider using a specialized anaerobic sealant designed specifically for those materials to achieve the best results without compromising bond strength. -
Question:
Is LOCTITE 518 resistant to oil and chemicals?
Answer: Yes, LOCTITE 518 is resistant to oils, fuels, and many chemicals, making it an excellent choice for automotive applications. This resistance helps maintain the integrity of seals in environments exposed to aggressive substances, thus preventing leaks and ensuring longevity. Users commonly apply it in situations where oil, grease, or chemical exposure is inevitable, particularly in automotive and industrial machinery settings. -
Question:
What is the curing time for LOCTITE 518?
Answer: LOCTITE 518 typically shows initial strength in about 60 minutes and achieves full strength within 24 hours. This rapid curing time makes it efficient for assembly processes, as it allows for quicker handling and operational readiness. Users appreciate being able to engage in immediate repairs or assembly tasks without lengthy waiting periods, making it a preferred choice in high-demand environments. -
Question:
How do you apply LOCTITE 518 for optimal results?
Answer: To apply LOCTITE 518 effectively, ensure that the surfaces are clean and free of contaminants. Apply a continuous bead around the flange area and assemble the parts immediately. Tighten the bolts to the recommended torque specifications to create a solid seal. This method ensures even distribution of the sealant. Many users note the importance of not over-applying, as excess sealant may ooze out and create messes or bonding issues. -
Question:
What is the shelf life of LOCTITE 518 once opened?
Answer: Once opened, LOCTITE 518 has a shelf life of about 12 months, provided it is stored properly in a cool, dry location with the cap tightly sealed. Users find that adhering to these storage guidelines helps maintain the sealant's effectiveness. It's advisable to label opened tubes with the date to monitor usage and ensure optimal performance during applications. -
Question:
Can LOCTITE 518 be used for high-pressure applications?
Answer: Absolutely, LOCTITE 518 is designed to withstand high-pressure environments, making it suitable for applications in hydraulic systems, automotive engines, and industrial machinery. Its high-strength formulation ensures it remains intact even under significant pressure fluctuations, providing reliable seals where it's most needed. Users often rely on its sealing capabilities in critical systems to maintain operational safety and efficiency. -
Question:
Is it safe to use LOCTITE 518 indoors?
Answer: Yes, LOCTITE 518 can be safely used indoors, but it's important to ensure adequate ventilation during application. While it does not emit harmful fumes, maintaining good airflow can enhance safety and minimize inhalation of any volatile compounds. Users frequently apply it in workshops, garages, or industrial settings where indoor environments are common, enjoying its strong sealing capabilities without concern. -
