Term: binder

In painting, a binder is the component of paint that holds the pigment particles together and helps the paint adhere to the surface being painted. It forms the paint film after the solvent or water evaporates. The binder is crucial for the durability, washability, and overall performance of the paint.

Common Types of Binders:

• Acrylic – Used in water-based paints; offers good adhesion, flexibility, and UV resistance.
• Alkyd – Found in oil-based paints; provides a hard, durable finish.
• Epoxy – Used in industrial coatings; known for chemical resistance and strong adhesion.
• Polyurethane – Offers excellent abrasion resistance and durability.

In summary, the binder is what gives paint its adhesive and film-forming properties, making it a key ingredient in any paint formulation.
