What is a chemical that causes two surfaces to stick together?

The term that describes a chemical that causes two surfaces to stick together is an adhesive. Adhesives are substances used to bond or adhere materials together, creating a strong bond upon drying or curing. They can be formulated from a variety of materials, including polymers, resins, and natural substances, and serve various purposes in multiple industries, including nail care.

While a bonding agent might seem similar, it typically refers to a specific type of adhesive used to improve the attachment of products, particularly in the context of beauty and nail applications. Solvents are chemicals used to dissolve other substances and do not create bonds between surfaces. Lubricants, on the other hand, are substances that reduce friction between surfaces but do not adhere them to one another. Hence, adhesive is the most accurate term for a chemical that facilitates sticking surfaces together.
