The decorative materials used in home decoration are paints and wallpapers. Paints are usually thick liquids made of resin, or oil, or emulsion, with or without adding pigments and fillers, adding corresponding additives, and prepared with organic solvents or water. The colorfulness of the world has created our love for different things. Interior decoration should be decorated with different colors of paint, whether it is wood or wall. And the products used for color mixing are color essence and color paste, but where can color paste and color paste be used?
The difference between color essence and color paste.
1, coloring mechanism is not the same: color essence in molecular form and the stained material for a kind of chemical action of the combination and staining, color paste in the state of particles, with tiny particles evenly distributed in the surface layer of the stained material, relying on matching adhesives to make it firmly attached to the surface of the colored material.
2, coloring role is different: color essence to molecular form dyeing, so there is a better transparency, such as wood paint, metal paint coloring, etc., color paste to tiny pigment particles state, there is a strong covering power, so clothing and other fabric printing pattern text, are required water-based printing paint color paste.
3, safety level gap: the existence of metal complex structure in the color essence, the presence of heavy metals is difficult to avoid, in some direct contact with the skin on the product, it is not recommended to use metal complex color essence as a coloring agent, color paste with pigment particles as the coloring body, as long as the choice of safe pigments and additives, water-based color paste safety is guaranteed.
4, the use of different scope: color essence is mainly used in wood coatings, leather coatings, paper coatings, paper coloring, printing inks, neutral ink, low temperature baking paint and so on. Color paste is mainly applied to interior and exterior wall coatings, wood coatings, watercolor, ink coloring, silicone coatings and so on.
5, the decorative effect is different: color essence color is more transparent, almost no coverage, commonly used in furniture panels colored transparent surface coloring. Add color essence of the paint, the more times the paint, the greater the thickness, the darker the color. Color paste, on the other hand, relies on the covering power to complete the coloring of the decorative surface, and the color of the bottom cannot be seen after painting, and is not affected by the number of times it is painted.
Similarities: color essence and color paste have in common is as a concentrated colored liquid, can be used for dyeing or coloring, both can be used in the home decorative use.
