2. Definitions of Glue, Adhesive, and Sealant

2.1 What is Glue?
Glue is a type of adhesive that is primarily used for bonding surfaces together using a wet or dry method. It's typically viscous and can set quickly upon contact with its surfaces.

2.2 What is Adhesive?
Adhesives can be defined as any substance that is applied to the surfaces of materials to bind them together. This category includes both glues as well as other bonding agents like tapes and pastes.

2.3 What is Sealant?
Sealants are designed to fill and seal gaps and joints, providing waterproof and weatherproof barriers. They are often used in construction to protect structures from water, air, and dust infiltration.
