Cure Monitoring of Hydrosilation-curable Silicones by Fluorescence Spectroscopy

摘要

The change in the fluorescence spectrum of BPEA in a hydrosilation-curable silicone can be measured reproducibly and related to the change in the elastic modulus of the silicone. In particular, the setting time of the silicone can be determined from the change in the fluorescence spectrum.Certain commercial equipment, instruments, or materials are identified here to adequately specify experimental procedure. Such identification is not intended to imply recommendation or endorsement by NIST, nor does it imply that the materials or equipment identified are the best available for the purpose.
