Varnishes and base coats are two different types of coatings, their characteristics and applications are very different, the main differences are as follows:
The composition is different: the main components of varnish are resin and solvent, and the resin can be natural resin or synthetic resin, such as natural paint, phenolic resin, amino resin, etc., while the color paint is a kind of paint containing color powder, and its main component is resin , solvents and pigments.
Different characteristics: varnish mainly protects, beautifies and improves the texture of the wood surface. It usually has the characteristics of transparency or translucence, which makes the wood texture more obvious, and at the same time protects the wood from ultraviolet rays, moisture, oxidation and other factors. The color paint is a kind of paint that can change the color and appearance of wood. Its color can be monochromatic or colorful, and it is often used to decorate and beautify the surface of wood products.
Different applications: Due to the different properties of clearcoats and basecoats, their applications also vary greatly. Varnish is mainly used in the surface treatment and protection of wood, such as furniture, floors, doors and windows, decorative materials, etc.; while paint is mainly used in the beautification and decoration of wood product surfaces, such as toys, handicrafts, wall coatings, stage decorations, etc.
Different requirements for use: Due to the different components and characteristics of varnishes and paints, they also have different requirements for use. Varnish usually needs to be used on a flat and smooth wood surface, requiring uniform coating film, high transparency, fast drying speed, high coating hardness, etc.; while the coating thickness of color paint is usually large, it requires uniform coating film, bright color, covering Strong, not easy to fade, strong adhesion, etc.
Different protective properties: the main function of varnish is to protect wood, prevent wood from being corroded by moisture, ultraviolet rays, oxidation, etc., and at the same time improve the gloss and aesthetics of the wood surface. Although the color paint also has a certain protective effect, its main function is to decorate and beautify, and enhance the decorative effect of wood.
Durability varies: Varnishes generally protect wood from attack for a longer period of time and are more durable than stains, but because varnishes are usually transparent or translucent, their protective properties may be compromised to some extent. The color paint usually has good hiding power and can protect the wood from erosion for a long time, but because the color and texture of the color paint are easily affected by the environment and use conditions, regular maintenance and repairs are required.
To sum up, although varnishes and pigmented paints are both coatings, their composition, characteristics, application and use requirements are very different, and they need to be selected and applied according to specific needs and use environments. To sum up, the characteristics of varnishes and pigmented paints are very different, and they need to be selected according to specific use requirements and conditions. If you need to protect wood and enhance its natural texture, you can choose to use varnish; if you need to decorate wood products and change its color and texture, you can choose to use stain.
