Surface treatment accounts for over 30% of the value of wooden handicrafts, and its technological route is transitioning from solvent based coating to environmentally friendly processes.

Comparison of mainstream technologies:

Advantages and limitations of technical types

The traditional raw lacquer process is acid and alkali resistant, repairable, and forms a dual texture of "paint film+wood skin". The drying cycle is long (30-60 days) and requires more than 15 processes

Water based paint spraying reduces VOC emissions by 80%, dries quickly (2-4 hours), has poor wear resistance, and requires regular maintenance

UV cured coating dries instantly in 3 seconds, with a hardness of over 3H. The equipment cost is high, and the curved surface is prone to "shadows"

Nano coating self-cleaning, anti fingerprint, light transmittance of 92%, scratch resistance weaker than paint film, needs to be used in conjunction with primer

Innovative Process Case:

A certain Japanese furniture brand adopts a composite process of "raw lacquer base coating+nano coating surface coating", which not only retains the warm touch of raw lacquer, but also achieves photocatalytic self-cleaning through a nano titanium dioxide layer, increasing the product premium rate by 60%.

Technological frontiers:

Biobased coating technology is on the rise, using vegetable oil and natural resin as raw materials, forming a dense film layer through enzyme catalyzed cross-linking reaction, which meets the requirements of the EU REACH regulation.
