Technology of extending data color matching;

(1) Because colors often have different color heads, yellow with green heads and blue with yellow heads are generally used when matching positive green; When purple and red are matched, blue with red head and red with blue head should be adopted; When matching orange, use red with yellow head and yellow with red head.

(2) Pay attention to the colors of auxiliary materials, such as drier, curing agent and diluent. , so as not to affect the color.

(3) When preparing multi-color paints such as gray and green, it is easy to appear "floating color" and "halo color" because of the different densities and oil absorption of various pigments. At this time, a small amount of surfactant, leveling agent and anti-floating agent can be added as appropriate to solve the problem.

Add 0. 1% silicone oil as usual for prevention. Various surfactants produced by foreign companies need to be used in different solvent systems, and the addition amount is generally 0. 1% ~ 1%.

(4) Using the characteristics of slightly transparent paint film, the color of topcoat can be more vivid than the original paint by choosing a suitable background color. This is a color produced by the superposition of background color and primary color according to the principle of natural light reflection and absorption, which is called "color penetration" in coating engineering.

For example, yellow primer can make red more vivid, gray primer can make red more vivid, positive blue primer can make black more vivid, and water blue primer can make white more clean and innocent. Cream, pink, ivory, sky blue and white should be used as primers.
