A curable composition, the cure of which can be monitored optically, comprises at least one of a hydride curable silicone, an ethylenically unsaturated compound, and a cationically polymerizable monomer, and as cure monitor dibenzofulvene or derivatives thereof. The cure monitor is a latent fluorophore which reacts under the cure conditions to form a UV-detectable fluorophore.
The invention also provides a method for measuring degree of cure of a polymeric material which can be a coating or an article.
一种可固化组合物,其固化可通过光学监控,包括氢化物固化硅酮、乙烯基不饱和化合物和阳离子可聚合单体中的至少一种,以及作为固化监控剂的二苯并呋喃或其衍生物。固化监测剂是一种潜伏荧光团,它在固化条件下发生反应,形成一种可被紫外线检测到的荧光团。
本发明还提供了一种测量聚合材料固化程度的方法,这种材料可以是涂层,也可以是物品。
