The curing requirements for UV varnish mainly include the following points:
Use specialized diluents: Due to the presence of multiple solvents in UV varnish, specialized diluents must be used to ensure curing effectiveness.
Substrate cleaning: Before spraying, the stains on the surface of the substrate should be cleaned thoroughly to ensure the adhesion coefficient.
Primer drying: The primer must be completely dried before applying UV paint, otherwise it may cause defects such as film shrinkage and biting.
Environmental requirements: Compressed air must be purified and must not contain oil or water. Spraying should be carried out in a dust-free environment to ensure the curing effect.
Post curing process: After UV curing, there is still a post curing process, and the workpiece should be properly protected after being cured and taken offline.
