darocur®1173
darocur®1173是一种高效不黄变的紫外光引发剂,用于引发不饱和预聚体系的uv聚合反应。
darocur®1173特别适用于一般uv固化体系。
cas no.:7473-98-5
外观:白色到淡黄色褐色液体
熔点:4℃
吸收峰:245nm,280nm(在甲醇溶液中)
应 用:
  darocur®1173​经过测试可单独使用或者与适当的引发剂(如irgacure 184,光敏剂)混合使用,用于纸张、金属和塑料表面的uv固化油墨和清漆。irgacure 1173特有的高吸收性使其特别适用于uv固化油墨。
  darocur®1173和光敏剂硫杂蒽酮混合使用。

application
darocur®1173may be used after adequate testing for applications such as uv curable clear coatings based on acrylates for paper, metal and plastic materials.
as a liquid uv curing agent with excellent compatibility, darocur®1173 is especially easy to incorporate. it is therefore highly suitable for blends with other photoinitiators.
darocur®1173 is especially recommended when uv coatings are required to exhibit only minimal yellowing even after prolonged exposure to sunlight. yellowing of urethane acrylates may be further reduced by addition of ciba specialty chemicals hindered amine light stabilizer tinuvin ® 292.the amount of  darocur®1173required for optimum performance should be determined in trials covering a concentration range.
recommended concentrations :
film thickness: 5 – 20 mm 2.0 – 4.0 %darocur®1173
film thickness: 20 – 2000 mm 1.0 – 3.0 %darocur®1173
safety and handling
darocur®1173should be handled in accordance with good industrial
practice. detailed information is provided in the safety data sheet.
