UV Coatings & Inks

      At present, domestic photocurable coating inks are mainly free radical systems. Photocurable ink coatings only account for 1-3% of global ink coatings. Free radical photocurable ink coatings do not achieve the desired results in some applications. There are still some bottlenecks that need to be broken. Some defects need to be improved, such as too much shrinkage and poor weatherability. And high halogen content. Cationic systems can compensate for these defects in free radical systems.


      Materials and cationic curing resins (clear coatings, inks, adhesives, stereolithography) Photocuring technology is a light processing process in which a liquid resin is polymerized at a high speed by a certain wavelength of ultraviolet light, which saves energy. It is solvent-free, has a protective effect on the ecological environment, and does not emit poisonous gas and carbon dioxide into the atmosphere, so it is known as “green technology”.


      A certain proportion of alicyclic epoxy resin needs to be added to the photocurable coating and ink.

      Fast curing speed, low shrinkage, no wrinkle on the surface, strong adhesion, corrosion resistance, not only retains the original epoxy resin performance, but also greatly accelerates the curing speed, so that it will cure in a few minutes or even seconds. Greatly increased labor productivity.

      The use of photocuring technology to obtain a hardened paint film and ink has the following advantages: energy saving, environmental protection, high quality and high efficiency.
