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.
在一般光化学研究和光固化应用中有实际意义的是中紫外和近紫外区的紫外光，通常又划分为以下三个波段: uv a, uv b 和 uv c。光固化体系常用uv a (315~400nm) 和 uv b (280~315nm)，集成电路制作的光刻技术常用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
应用于竹木地板、塑料、纸品、金属、光纤、皮革、陶瓷、石材等。used in wood flooring, plastic, paper, metal, optical fiber, leather, ceramic, stone, etc.
光固化油墨/uv cured ink
应用于包装装潢、印刷、电子 (抗蚀油墨、阻焊油墨、标记油墨) 等。
used in packaging, printing, electronics (anti-corrosion ink, solder mask ink, marking ink), etc.
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.
used for photolithography in photosensitive materials.
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.
