Take you to understand UV curing coatings in one minute
光固化涂料主要指在紫外光照射下迅速交聯固化的一類新型涂料，通常指從液體樹脂變成固態干膜的過程。因其高效涂裝固化、低能耗和環境友好特征，已為世界涂料行業認可，近年來發展迅速。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.
UV cured coating was put into commercial production by Bayer in the 1960s.
Over 22,000 tons UV cured coating was globally used on wood only for furniture in 2000.
Up to 53,000 tons UV cured coatings was used in packaging industry in 2010.
Till date, a huge number of UV cured coatings have been applied on paper, plastic, metal, glass, ceramic and many other substrates.
在一般光化學研究和光固化應用中有實際意義的是中紫外和近紫外區的紫外光，通常又劃分為以下三個波段: UV A, UV B 和 UV C。光固化體系常用UV A (315~400nm) 和 UV B (280~315nm)，集成電路制作的光刻技術常用UV C (200~280nm)。
In general photochemical research and UV curing applications, UV light is usually divided into the following three bands during the mid-ultraviolet and near-ultraviolet regions, including UV A, UV B and UV C. Among them, UV A (315~400nm) and UV B (280~315nm) are commonly used in UV cure system. UV C (200~280nm) is usually applied in lithography technology for integrated circuit production.
光固化涂料/UV cured coating
光固化油墨/UV cured ink
應用于包裝裝潢、印刷、電子 (抗蝕油墨、阻焊油墨、標記油墨) 等。
Used in packaging, printing, electronics (anti-corrosion ink, solder mask ink, marking ink), etc.
光固化膠黏劑/UV cured adhesive
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.
用于光刻術的感光材料。Used for photolithography in photosensitive materials.
三維激光成型/3D laser forming
20世紀80年代末發展起來的快速成型技術，利用激光引發感光樹脂的聚合，要求感光樹脂低粘度、高固化速度、低收縮、低溶脹、層間黏附相容性好、光敏感度高等。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.
自由基型光引發劑 (Free radical photoinitiator) /
陽離子型光引發劑 (Cationic photoinitiator)
Photosensitive part includes oligomer and reactive diluent, which accounts for over 90% of the entire formula.
