UV cured coatings and photoinitiators

UV cured coating mainly refers to a new type of coating which is quickly cross-linked and cured under ultraviolet (UV) irradiation. It usually refers to the process of changing from a liquid resin to a solid dry film. Because of its high-efficiency curing process, low energy consumption and environment-friendly characteristic, UV cured coating has been globally recognized by the coating industry. It has developed rapidly in recent years. 

Application of UV cured coating

1

UV cured coating is used in wood flooring, plastic, paper, metal, optical fiber, leather, ceramic, stone, etc.

2

UV cured ink is used in packaging, printing, electronics (anti-corrosion ink, solder mask ink, marking ink), etc.

3

UV cured adhesive is divided into structural adhesives, sealants, laminating adhesives, pressure-sensitive adhesives, etc. Used in optical lens assembly, crystal crafts, microelectronic assembly, metal and plastic bracket bonding, disposable medical equipment, LCD display assembly, glassware bonding, etc.

4

Photoresist is used for photolithography in photosensitive materials.

5

3D laser forming: The rapid prototyping technology was developed in the late 1980s. It uses laser to initiate the polymerization of photosensitive resins. The photosensitive resin must possess low viscosity, high curing speed, low shrinkage, low swelling, good interlayer adhesion compatibility and high photosensitivity.
