An Application Of UV Test Chamber：uv-curable High Hardness Coating

We all know that coating is needed everywhere in life, of course, for some special environmental factors, we have to develop more targeted coatings that meet the needs of the public. Today we talk about UV curing high hardness transparent coating. As long as you have a UV test chamber, you can easily use this coating.

So what is UV?

UV is short for Ultraviolet Ray. Ultraviolet light is an electromagnetic wave with a wavelength between 10 nm and 400 nm, shorter than visible light but longer than X-rays. Sunlight contains part of the ultraviolet light, electric arc, mercury lamp, black light will also emit ultraviolet light. Industrial UV wavelengths range from 200 nm to 450 nm. The Process of curing the special material by irradiating it with UV is called “UV Curing Process”. We provide the UV light required for this process through a UV test chamber.

What is UV curing?

UV curing generally refers to the curing conditions or requirements of coating materials (paint), adhesives (glue) or other potting sealants that need to be cured by ultraviolet light. It is the use of ultraviolet light energy to trigger the polymerization and cross-linking reaction between the low molecular prepolymers or oligomers of paint species and monomer molecules as active diluents, to obtain hardened paint film. In essence, through the formation of chemical bonds to achieve chemical drying.

The UV coating material can be coated by dipping, spraying, lacquer, spin coating, and even vacuum coating, and then cured into a film by ultraviolet photon irradiation. As the name suggests, the curing of UV coating materials is inseparable from the irradiation of UV light. Curing is a process by which a substance changes from a low molecule to a high molecule. , Different from temperature curing, adhesive curing, natural curing, this technology originated in the international paint market in the 1970s and is a new green technology.

Advantages of UV-curable high hardness coatings

UV curing high hardness transparent coating does not contain volatile organic compounds (VOC), has excellent hardness and permeability, low crimp and excellent solubility and chemical resistance. The environmental pollution is small, curing speed is fast, energy saving, curing product performance is good, suitable for high-speed automated production. However, traditional coatings are volatile and slow to cure, which is not conducive to environmental protection. Therefore, UV-curable high-hardness transparent coatings are the main alternative to traditional coatings.

UV curing high hardness transparent coating is suitable for spray printing on metal, glass, ceramics, density board, PC, PVC, ABS, PMMA, PET/TAC film and other materials surface. It wipes directly to the surface of the material, good firmness, waterproof and UV proof.

We all know that the printer prints patterns, and the raw materials should be treated externally, that is, a layer of appearance treatment agent (coating) is sprayed on the surface of the raw materials. In fact, the surface treatment agent (coating) is called UV curable coating, which is used to improve the adhesion of the pattern, so that it can be cured on the surface of the substrate for a long time. And the UV-curable coating is a transparent liquid that is used to improve the adhesion of the UV ink on the pattern, making the pattern clearer.
