>> 性能和用途(Properties and uses)
PI 307是新型光引发剂可以替代传统的907型光引发剂，是907由于生物毒性于2011年被欧盟限制使用后唯一的高性价比的替代品。
PI 307的优点是：
分子结构不含硫元素，因此光固化后没有907特有的难闻残留“中药味”
分子结构不含苯元素，不致癌
显著地耐黄变，单独使用时可以用于清漆体系
可以用于烟包酒标等对VOC释放量严格控制的高端UV应用领域
PI 307 is a new type of photoinitiator that can replace traditional 907 photoinitiators. It is the only cost-effective alternative to 907 after its biological toxicity was restricted by the European Union in 2011.
The advantages of PI 307 are:
The molecular structure does not contain sulfur-containing elements, so there is no unpleasant residual "traditional Chinese medicine flavor" unique to 907 after UV curing
Molecular structure does not contain benzene and is not carcinogenic
Significantly resistant to yellowing, can be used alone in varnish systems
Can be used in high-end UV applications such as cigarette packaging and wine labeling that strictly control VOC release levels
