One thing that binds things together is adhesive. Adhesive refers to a substance that is used to stick or join two or more objects together. Adhesives can be found in various forms, including liquid, gel, solid, or tape. They are used in a wide range of applications, such as crafts, construction, woodworking, packaging, and even in medical procedures.

There are different types of adhesives available, each with its own unique properties and areas of application. Some common types include:

1. Epoxy adhesives: Epoxy adhesives consist of two components, a resin and a hardener, which need to be mixed before use. Once mixed, they create a strong and durable bond. Epoxy adhesives are often used in construction, automotive, and aerospace industries.

2. Silicone adhesives: Silicone adhesives are known for their flexibility and resistance to high temperatures. They are often used in electronics, automotive, and medical applications.

3. Pressure-sensitive adhesives: These adhesives remain tacky and sticky even without the application of heat or solvents. They are often used in tape and label applications.

4. Hot melt adhesives: Hot melt adhesives are solid at room temperature but melt when heated. They are commonly used in packaging, sealing, and bonding applications, as well as in crafts.

5. Wood glue: As the name suggests, wood glue is specifically designed for bonding wood surfaces together. It provides a strong bond and is commonly used in woodworking projects.

The choice of adhesive depends on the specific materials being bonded, the application requirements, and the desired strength and durability of the bond.
