TWO-COAT TWO-BAKE POWDER COATING STRUCTURE AND APPLICATION METHOD THEREOF
20210291225 · 2021-09-23 ·

The present invention relates to a two-coat two-bake powder coating structure and application method thereof that mainly utilizes high concentrated migratory pigment and dye powder in the primer layer that osmotically diffuses into the finish layer of colorless powder during baking after the finish layer undergoes the electrostatic spray process. The principle is to apply a second baking process to the migratory pigment and dye powder, causing the molecular chains of the primer layer to become loose. As a result, the small molecules of the migratory pigment and dye powder can uniformly move from the primer layer into the finish layer across the interface between the primer layer and the finish layer through osmosis and diffusion. After the finish layer cools down, the migratory pigment and dye powder is solidified within the finish layer so that the chromatic aberration of the surface coating layer is improved.

PROCESS FOR THE PRODUCTION OF A MULTILAYER MATTE COATED SURFACE AND A PRODUCT CONTAINING A MULTILAYER COATED SURFACE

Invention concerning a method for the production of a multilayer matte coated surface, where the carrier (1) is covered with a layer of coating (4) containing an additive to increase the bond strength of the coating between the layers. The coating layer is exposed to excimer radiation with a wavelength of 172 nm and afterwards treated with an electron beam with the dose required to achieve the gelatinisation of the coating, or with UV radiation in order to obtain an adequate gelatinisation effect. A least one other layer of coating with bond strength improving additive is applied to the first layer, which is again exposed to excimer radiation and an electron beam or UV radiation with the same dose as for the first layer. if the second layer is the outer layer, i.e. the last layer (6), the entire surface is treated with an electron beam with the dose required to finish the polymerisation process of all coating layers, or is treated with appropriate UV radiation, in order to achieve an adequate hardening effect.

The invention concerns also a furniture product containing a multilayer matte coated surface obtained with the method according to the invention.
