Anaerobic gasket makers are sealants that cure in the absence of air and in the presence of metal ions. They are used to create a reliable seal between two metal surfaces, preventing leaks of gases or liquids. The process begins when the gasket maker is applied to a clean, dry surface. The sealant remains in a liquid state until the parts are assembled and the air is excluded. 
Once the parts are joined, the absence of oxygen triggers the curing process. Metal ions, typically from the surfaces being sealed, act as a catalyst to initiate polymerization. This chemical reaction transforms the liquid sealant into a solid, thermoset plastic, filling any gaps or irregularities between the surfaces. The result is a durable, flexible seal that can withstand high pressures, temperatures, and chemical exposure.
Anaerobic gasket makers are particularly advantageous because they eliminate the need for pre-cut gaskets, allowing for a custom fit. They also provide excellent resistance to vibration, thermal expansion, and contraction, making them suitable for a wide range of applications, including automotive, aerospace, and industrial machinery. 
The curing time can vary depending on the specific formulation and environmental conditions, but it typically ranges from a few minutes to several hours. Once cured, the sealant can be difficult to remove, often requiring mechanical scraping or chemical solvents. 
Overall, anaerobic gasket makers offer a versatile and efficient solution for sealing metal components, ensuring leak-proof performance in demanding environments.
