Top 5 Applications of Anaerobic Adhesives in Industry

Anaerobic adhesives represent one of the most advanced solutions in the field of bonding and sealing components in industry. Thanks to their unique technology, these adhesives are distinguished by their ability to polymerize in anaerobic conditions, making them indispensable for many critical applications. Based on modern chemical formulas, anaerobic adhesives offer exceptional durability, resistance to extreme conditions, and the ability to seal connections with complex shapes.

How do anaerobic adhesives work?

The mechanism of anaerobic adhesives is based on a chemical reaction initiated in an oxygen-free environment. When the adhesive is applied to a thread surface and oxygen access is cut off by tightening the components, the polymerization process begins. Catalytic curing starts upon contact with metals due to the presence of active ions on their surface. This reaction leads to the formation of a durable, homogeneous bond that exhibits high mechanical and chemical resistance.

Key properties and the polymerization mechanism

Anaerobic adhesives are characterized by several essential properties that determine their widespread use in the industry. First and foremost, they offer shear and tensile strength, making them ideal for securing screws, threads, and other mechanical connections. The polymerization process results in a durable polymer network resistant to temperature, pressure, and chemical agents.

Thanks to anaerobic curing technology, anaerobic adhesives are perfect for applications requiring resistance to vibrations and dynamic loads. Their ability to fill micro-damages and eliminate leaks allows for the creation of durable seals in critical connections such as hydraulic systems or gas installations. The mechanism of action and versatility of these adhesives make them a key tool in industries like automotive, aerospace, energy, and machinery.
