Can I customize the color of my car paint using automotive paint pigments?

Yes. Blending of car paint is a very delicate process. It needs several steps to get the final color. First, prepare a base color. It is usually made by mixing several colors. Then, add auto paint pigments and colorants according to customers’ color requirements.

Some special tools and equipment are used to ensure the accuracy and consistency of colors after blending. For example, a weighing device is needed to accurate weigh each automotive pigment, thus ensuring the accuracy and consistency of each formula. A special blender is also needed to mix all automotive pigments with the base color to get the final color.

Pay attention to some factors during blending, as these factors may affect the color. In addition, the quality of the materials and surfaces should be considered, which will also affect the color.

In short, blending of car paint is very complex. Experienced professionals and sophisticated tools and equipment are needed to ensure the accuracy and consistency of colors. Tus, high-quality car paint can be produced according to customer requirements.

What role do car paint pigments play in car paint?

Car paint pigments are important color sources of auto paint. They are both colorants and secondary film-forming substances in paints. They have certain covering power and coloring effects on paint films. More importantly, pigments can enhance the protection properties of paints.

Car pigments are bones of paint films, like gravels in concrete. As automotive pigments are closely bonded with base materials, they can cover the base layer, block light, and improve the water resistance, light resistance, weather resistance, mechanical strength, hardness and wear resistance of paint films, thus extending the service life of paint films.

Car paint pigments have beautiful colors and high coloring and covering power. Common pigments in paints include titanium dioxide, lithopone, carbon black and iron oxide pigments, organic pigments, inorganic pigments and metallic pigments.

How does automotive pigment affect the gloss of automotive paint?

  1. Particle size
    The particle size of automotive pigment powders and dispersion in base materials affect the gloss of paint films. Fine automotive pigments can be dispersed well in base materials to form smooth paint films.
  2. Car paint pigment concentration
    The binder ratio of paint affects the gloss of film. car paint pigment pigment particles of paint will weaken specular reflection, resulting in a decrease of gloss. With the pigment volume concentration (P.V.C) increasing, the gloss will decline. At a certain binder ratio, pigments will absorb more oil and further reduce the gloss.
  3. Car paint color
    Car paint pigments in different colors vary in light absorption and reflection. White paint completely absorbs light, while white light fully reflects light. Therefore, black paint is glossier than white paint.
  4. Solvent type and flatness
    The type of solvent in paint directly affects the rate of volatilization. Volatilization at a too high or low rate will affect the film flatness and reduce the film gloss.

The gloss of the film surface depends on its flatness or roughness. The incidence angle of light will also affect the gloss. The larger the incidence angle, the higher the intensity of reflected light.

Do car pigments have an impact on the drying time of car paint?

Car pigments affect the drying speed of car paint. Different paints vary in the drying speed. For example, polyurethane paints become dry more slowly than alkyd paints.

What pigment is used in car paint?

Pigments in car paints include:

  1. Anti-corrosion car pigments: they are widely applied to enhance the anti-corrosion of primer.
  2. Extender car pigments: they can improve the thickness and abrasiveness of paint films. They are mainly used in primer and other coatings.
  3. Coloring car pigments: they can improve the color and covering power. (Inorganic pigments, i.e. metal oxides, are usually dark-colored, such as titanium dioxide and iron oxide red pigments. Organic pigments mainly have bright colors but low covering power, such as phthalocyanine blue and atebrin red.)

What automotive color shift pigment used in paint changes color for cars?

Color-changing car paint (spray type color-changing ink) is a special paint for color changes with the assistance of other substances.

Categories: temperature-dependent paints, UV color-changing paints, paints with natural color change at different angles (chameleon paint), etc.

Temperature-dependent paints are divided into a variety of special color-changing paints depending on the temperature, such as paints for coloring and discoloration in heating, paints for coloring or color change in cooling, etc. These paints change colors based on the temperature. They also include the microcapsules, which are encapsulated by the compounds hat change colors after chemical reaction in heating.

Basic colors: black, sapphire blue, dark blue, sea blue, bright red, scarlet, pink, orange red, golden yellow, grass green, peacock green, dark green, etc. (adjustable)

Basic temperatures: -5℃, 0℃, 5℃, 10℃, 16℃, 21℃, 31℃, 33℃, 38℃, 43℃, 45℃, 50℃, 65℃, 70℃, 78℃.

UV color-changing paint is a kind of light-sensitive microcapsule, which changes the color due to excitation in the presence of UV light.

What is pearl powder for car paint?

Pearl pigment automotive paint, also known as mica paint, is a kind of car paint. Mica powder is used instead of aluminum particles. Mica pigments coated with titanium dioxide and iron oxide are added into the paint base. If mica particles are irradiated by light, the color of titanium dioxide and iron oxide will appear. In addition, complex refraction and interference occur in mica particles.

Mica itself has a special transparent color. Therefore, the reflected light has a pearl-like gloss.

Titanium dioxide is yellow itself. It looks light blue if it is seen from a certain angle. That is, it has different colors at different angles. Pearlescent paint looks novel, colorful and dazzling.

How does chameleon pigment car paint work?

Chameleon car paint is a paint with a special effect that changes color depending on the ambient temperature and light. The principle of this amazing paint is based on temperature-sensitive pigments and the principle of light reflection.

Thermochromic pigments are one of the core components of Chameleon auto paint. It is a substance that changes color according to temperature. At low temperatures, the pigment takes on one color, and at high temperatures another. This characteristic makes chameleon paint show different colors in different ambient temperatures, giving people a feeling of unpredictability.

In addition to temperature-sensitive pigments, Chameleon automotive paints also utilize the principle of light reflection to enhance the effect of color change. Light reflection is a phenomenon that occurs during the propagation of light from one medium to another. When light strikes the surface of a chameleon paint, the pigments in it absorb some of the light and reflect others. Different colors absorb and reflect different wavelengths of light, making different colors visible to the human eye.

Chameleon paint in the automotive field, can be used for body painting, so that the car in different ambient temperatures shows different colors, increasing the personalization of the vehicle and the sense of fashion in the field of clothing, it can be used to make fashionable color-changing clothing, so that people in different occasions glow with different charms.
