Loctite 510 vs. 518: Flange Sealant Face-Off
Loctite 510 Overview
High-Temperature Resistance
LOCTITE® 510 is known for its remarkable high-temperature resistance, making it an ideal choice for applications exposed to extreme heat. This form-in-place anaerobic-curing sealant provides an instant, low-pressure seal when confined between close-fitting metal surfaces. It is particularly suitable for rigid flanges, including those found in transmissions and motor casings. The unprimed gap-fill for Loctite 510 is 0.25 mm (0.01″).
| Product | Max Temperature (°C) | Gap Fill (Unprimed) |
|---|---|---|
| Loctite 510 | 200°C | 0.25 mm |
Application and Benefits
Loctite 510 offers several advantages, particularly in its application and long-term benefits. One of the primary benefits is its suitability for use on aluminum and steel substrates. This makes it an excellent choice for industries requiring robust and durable sealing solutions.
One of the standout benefits of Loctite 510 is its ability to create a reliable seal that remains effective over time. Unlike pre-cut gaskets that need to be precisely measured and managed, liquid gaskets like Loctite 510 can be applied to an infinite range of flange patterns, significantly reducing inventory costs. This flexibility is invaluable in various industrial applications (Henkel Adhesives).
| Benefit | Description |
|---|---|
| High Temperature | Resistant to extreme heat up to 200°C |
| Application Flexibility | Suitable for various flange patterns |
| Chemical Resistance | Resistant to gasoline, diesel, engine oil, water, glycol, acids, alkalis, hydraulic fluid, and more (Henkel Adhesives) |
Furthermore, Loctite 510 eliminates potential leak paths by providing a seal that won’t shrink, compress, crack, or relax over time. This ensures a leak-free performance, contributing to the overall reliability and efficiency of the machinery it protects.
