Mayer Rods for prepative UV coatings

UV coating is a kind of coating based on ultraviolet light curing technology. By adding ultraviolet sensitizer and photoinitiator to the coating, it can be cured rapidly under ultraviolet irradiation. UV coating has the advantages of fast curing, effective, high hardness, high transparency, high gloss, environmental protection, etc., and is widely used in electronics, automobiles, printing, plastics and other fields.

In terms of wire rod coaters, for UV coatings, stainless steel wire rods are recommended, because stainless steel materials have good corrosion resistance and thermal stability, and can withstand high temperature and high energy under ultraviolet irradiation.

The steps to prepare a UV coating film using a wire Bar Coater are as follows:

1. Prepare UV paint solution: Mix UV paint and solvent and stir well.

2. Prepare the substrate: select a suitable substrate material, and perform surface cleaning and pretreatment.

3. Coating: The UV coating solution was uniformly coated on the surface of the substrate using a wire Bar Coater.

4. Ultraviolet radiation: Put the coated sample under the ultraviolet irradiator and irradiate for a certain period of time, so that the UV coating can be cured rapidly.

5. Finally, follow-up steps such as electrode preparation and testing are carried out.

NBCHAO reminds you: During the coating process, the coating speed, temperature, pressure and other parameters of the wire rod should be adjusted according to the characteristics of the coating and the parameters of the applicator to obtain a high-quality UV coating film. When irradiating with ultraviolet rays, the irradiation time should be adjusted according to the thickness of the coating and the power of the ultraviolet irradiator to ensure that the coating is fully cured.
