Reasons for the matte surface of color-coated plates:
1. The surface of the substrate is too rough or has oil, moisture, wax, etc. And the coating is not completely cured.
2. The color-coated plate paint is not fully mixed before the machine is started, and the paint solids sink to the bottom of the barrel, resulting in less pigment in the barrel during construction.
3. The excessive diluent used in the coating dilutes the effect of the glossy coating.
4. Due to the paint formula, the amount of pigment, filler, and solvent in the paint is too much, the fineness is not enough or there is dust.
5. The surface coating of the color-coated plate is too thin, and the roller-coating room temperature is too high or too low during construction. In addition, if the temperature of the curing furnace is set too high, the hot air circulation in the furnace is insufficient, and the paint is baked too much, it will also cause dullness.
When using color-coated plates, everyone should pay attention to the above factors to ensure that the gloss of its surface will not change.
