Lacquer paint is a broad term generally used to describe a range of solvent-based coatings that provide a durable and high gloss finish to furniture and other items. Traditionally, it refers to a clear or colored varnish that dries by solvent evaporation and often a curing process that produces a hard, durable finish, usually on wood. The term "lacquer" originates from the Portuguese word "laca," which is derived from the lac, a form of resin secreted by certain insects.
Lacquer paints are made by dissolving a synthetic resin – typically nitrocellulose – but sometimes acrylic, or other plastics, in a solvent that may include volatile organic compounds (VOCs). When the lacquer paint is applied to a surface, the solvent evaporates quickly, leaving the resin to harden into a protective coating.
Types of Lacquer:
Nitrocellulose Lacquer: Made from an ester of cellulose, it provides a high-gloss finish, dries quickly, and is durable. This was extensively used in the automotive and furniture industries until newer, more environment-friendly alternatives became available.
Acrylic Lacquer: Utilizes acrylic polymers and offers improved UV resistance and less yellowing over time compared to nitrocellulose lacquer. It's often used on automobiles and guitars.
Water-Based Lacquer: Common in more environmentally-conscious products, these lacquers use water as the primary solvent, significantly reducing VOC emissions. They take longer to dry and may not be as durable as solvent-based lacquers.
