Anti-seizes are a type of lubricant used in industrial and scientific settings to prevent metal-to-metal contact and corrosion. They are typically made of a mixture of metallic particles and a carrier oil or grease. Anti-seizes can withstand high temperatures and pressures, making them ideal for use in machinery and equipment that undergoes frequent wear and tear. They also help to prevent galling, which is the process of metal surfaces sticking together due to friction. Anti-seizes are available in various formulations to suit different applications and are an essential component of any industrial or scientific maintenance program.

Frequently Asked Questions (FAQs)
1. What is anti-seize used for?
Anti-seize is used to prevent galling, seizing, and corrosion on bolts, fasteners, flanges, and other clamped interfaces. It also provides lubrication to ease disassembly.
2. What shouldn't you use anti-seize on?
Anti-seize should not be used on already damaged or cross-threaded threads of bolts. The threads should be repaired before applying anti-seize. It is also not recommended to use anti-seize on exposed threads as it may attract contaminants that can contribute to thread damage.
3. Will wd40 work as anti-seize?
No, WD-40 is not an anti-seize compound. While it may provide some lubrication, it is not designed to withstand high temperatures or provide lasting lubrication like anti-seize.
4. When should anti-seize be applied?
Anti-seize should be applied when working with dissimilar metals, where threads may be exposed to corrosive effects, in high-heat environments, and on fasteners that are frequently removed.
5. Is anti-seize better than grease?
Anti-seize products contain solid lubricants along with a grease base, providing lubrication at both lower and higher temperature ranges. This makes anti-seize more effective than regular grease for certain applications.
6. How long does anti-seize last?
The shelf life of anti-seize can be 5 years or more when stored in a closed container in a cool dry place. However, the actual shelf life may vary depending on storage conditions.
7. Can I use Vaseline instead of anti-seize?
No, Vaseline, petroleum jelly, or soft soap are not recommended as anti-seize compounds. They function more as lubricants rather than anti-seize compounds and are not suitable for high temperature and pressure applications.
8. Where do you apply anti-seize lubricant?
Anti-seize lubricant can be applied to flanges, bolts, fasteners, and other clamped interfaces. It comes in various forms such as sprays and paste, and helps with disassembly and extending machinery life, especially when working with dissimilar metals.
