Carbon Black Pigment plays a role in coatings and paints. It is widely used in coatings and paints for construction, automobiles, and ships, or plays a coloring role. Carbon Black Pigment has advantages in tinting strength and price, and has become a popular choice for coatings and paints. An indispensable black pigment for the industry.
1. Carbon black can improve the ability to absorb ultraviolet rays.
2. Carbon black can improve gloss.
3. Carbon black can improve the leveling properties of paints.
4. Carbon black can improve the durability of coatings and paints.
Some indicators of carbon black for coatings and paints:
1. The blackness of Carbon black pigment :
The blackness requirements of carbon black are different under different functions. For example, when used for coloring, the higher the blackness of carbon black, the better. When used for color mixing, high blackness can easily lead to color differences in different batches of products, so carbon black with lower blackness can be used.
2. Tinting power of carbon black pigment :
It can also be called tinting strength. When different pigments are mixed with carbon black powder , the coloring ability displayed by carbon black. Carbon black can improve the absorption of light. This indicator depends on the mix. Specific amount and the properties of carbon black itself. The smaller the carbon black particle size and lower the structure, the stronger the tinting power, but this ability becomes weaker after reaching the limit.
3. The hue of carbon black pigment:
The particle size and structure of carbon black will affect it. Low structure and fine particle size can produce a blue phase, while high structure and coarse particle size can produce a brown phase.
4. Gloss of carbon black pigment :
When the carbon black particle size is small or the structure is high, the oil absorption of carbon black increases, the viscosity of the paint will also increase, the film-forming substances of the coating will decrease, and the gloss will decrease.
