What are the main reasons for the discoloration of Zhongshan medals?
The main reasons for the color leakage of wooden pallets are as follows:
1. When the bottom layer of paint coating is not fully dry, apply the top layer of paint coating.
2. Apply a strong solvent topcoat paint coating on a general base coat paint coating.
3. Some organic pigments (such as phthalocyanine blue, phthalocyanine green), asphalt, creosote, etc. are used in the underlying paint coating.
4. Wood contains certain organic dyes, wood glue, etc. If not coated with sealing coatings, it is easy to cause color bleeding over time or at high temperatures.
5. The color of the bottom paint coating is deep, while the color of the surface paint coating is light, and it is also prone to color bleeding.
