Epoxies are made to suit various operating conditions and applications. דבק אפוקסי adheres to various materials and their properties depend on the system’s specific chemistry and cross-linking nature. The glue should be heat, water and chemical resistant. It should also have excellent electrical insulating and adhesion properties.
One Component and Two Component Systems
Epoxy is one of the most common types of adhesive used today. It is usually offered as two component or one component systems.The latter is usually cured at 250 to 300 degrees Fahrenheit. These temperature conditions create a product with exceptional strength and adhesion to metal sand resistance to harsh chemicals and environmental factors. One component systems are often used as a substitute to rivets and welding. It is made pre-catalyzed and needs moderate heat to cure, preventing errors that may arise from air entrapment and improving efficiency. The speed of cure is also faster than a two component system.
Catalyzation is different for two component epoxy systems as it happens at ambient temperatures, which can be enhanced by heat. This also promotes further cross-linking, which results in superior properties. A two component system is ideal for bonding a wide range of surfaces. It’s also considered very stable as it can endure a constant force or weight over a long period of time. Two component systems are resistant to chemical and physical influences as well. These properties make two component systems a very stable product.
Epoxy glue is also very versatile, so it can be used for various applications such as coating, bonding, encapsulation and sealing. Various industries can benefit from epoxy glue, including aerospace and electronics. There are also special formulations that are resistant to high temperatures and flames and are fast curing. It can be used in jewelry making as well as woodworking.
