Frequently Asked Questions (FAQs)
1. What is anti seize lubricant used for?
Anti-seize lubricants are used to prevent galling, seizing, and corrosion in metal interfaces such as bolts, flanges, and fasteners. They also provide lubrication to facilitate easy disassembly.
2. Where should you not use anti seize?
Anti-seize should not be used on already damaged or cross-threaded threads of bolts. It is important to chase, re-tap, or repair the threads before applying anti-seize. Additionally, it should not be used on exposed threads as it can attract contaminants that may contribute to thread damage.
3. Can I use WD40 instead of 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 long-lasting lubrication like anti-seize compounds.
4. What can I use instead of anti seize lubricant?
For preventing galvanic corrosion, silicone grease is a better alternative to anti-seize lubricant.
5. How long does anti seize last?
The shelf life of anti-seize lubricant is typically 5 years or more when stored in a closed container. However, the actual shelf life can vary depending on storage conditions. It is recommended to store the lubricant in a tightly sealed container in a cool dry place for optimal shelf life.
6. What are the side effects of anti-seize lubricant?
Anti-seize lubricant may cause mild irritation to the eyes and prolonged contact may lead to skin irritation and drying. It may also cause an allergic reaction. However, at ambient temperatures, no adverse effects are expected from inhalation.
7. Can you use PB Blaster as anti seize?
PB Blaster is not specifically designed as an anti-seize lubricant. While it has properties that provide lubrication and can prevent seizing over time, it is not a substitute for dedicated anti-seize compounds.
8. Is anti seize lubricant necessary?
Anti-seize lubricant is necessary in various situations, such as when working with dissimilar metals, where threads may be exposed to corrosive effects, when high heat can accelerate corrosion, and on fasteners that are frequently removed. It helps protect against galling, seizing, and corrosion, ensuring smooth disassembly and preventing damage to the components.
