What is another name for binder in painting?

Binder in painting is commonly referred to as resin. The binder plays a crucial role in the composition of paint, serving as the film-forming component that holds the pigment particles together and ensures they adhere to the surface being painted. Resins provide the necessary properties for durability, adhesion, and overall performance of the paint.

For example, in oil-based paints, the binder is usually a drying oil, while in latex paints, synthetic resins are used. This distinction highlights the importance of the binder in defining the characteristics of the paint, such as its gloss, flexibility, and resistance to weathering.

The other options do not accurately reflect the function of a binder. Solvents are used to dissolve the binder and make the paint easier to apply, while water, specifically in water-based paints, acts as a solvent rather than a binder. Adhesive generally refers to substances that bond materials together, which isn't specific to the properties of paint binders. Thus, the term resin is the most appropriate synonym for binder in the context of painting.
