Why is epoxy glue so expensive?

Epoxy glue is more expensive compared to other types of glue for several reasons:

1. High-quality ingredients: Epoxy glue is made from a combination of resin and hardener. These ingredients are typically of high quality and undergo a complex manufacturing process, which adds to the cost.

2. Superior bonding strength: Epoxy glue is known for its exceptional bonding strength, making it suitable for a wide range of applications. This strength is achieved through the chemical reaction between the resin and hardener, which requires precise formulation and quality control, driving up the cost.

3. Versatility and durability: Epoxy glue is highly versatile and can bond various materials such as metal, wood, plastic, and ceramics. It also offers excellent resistance to heat, chemicals, and moisture. The extensive research and development required to achieve these properties contribute to its higher price.

4. Longer shelf life: Compared to other glues, epoxy has a longer shelf life due to its two-component formulation. This means that the resin and hardener are stored separately and mixed only when needed. This extended shelf life requires additional packaging and storage considerations, increasing the overall cost.

5. Specialized applications: Epoxy glue is commonly used in industries such as construction, automotive, aerospace, and marine, where its unique properties are essential. These specialized applications often require higher quality and performance standards, leading to increased costs.

Overall, the higher price of epoxy glue is justified by its superior bonding strength, durability, versatility, and specialized applications.
