The volume solid content of alkyd resin coating is generally 40%~50%, and the dry film thickness during construction is 30~50µm, which should not be too thick. This is because the alkyd resin coating is an oxidative polymerization type coating. If the coating film is applied too thick and the surface coating is dried and formed, the drying of the bottom layer will be affected because the oxygen cannot fully diffuse to the bottom layer in time, and the surface of the coating will wrinkle. .
The volume solid content of high solid alkyd resin coating is more than 50%, and it can be applied in thick film type, and the dry film thickness can reach 50~80μm or even higher in one spraying.
