Butyl acetate is widely used in paints. It can be used as a solvent to make the paint have good fluidity, uniform and smooth application, and flat film formation. In resin-based paints, it can dissolve the resin, help it disperse, and ensure the stability of the paint's performance. In volatile paints such as nitro paints, the volatilization rate of butyl acetate is moderate, which can not only allow the paint to dry quickly and form a film, but also avoid rough and wrinkled surface of the film due to excessive drying. And because of its good solubility to a variety of pigments, it can effectively disperse pigments, make the paint color uniform and bright, and improve the hiding power and color expression. Furthermore, it can improve the leveling of the paint, make the paint spread evenly on the surface of the object, reduce the undesirable phenomena such as flow marks and orange peel, and greatly improve the aesthetics and quality of the paint surface. Therefore, butyl acetate plays a key role in the production and application of paint, contributing greatly to the improvement of paint quality and use effect.
