Abstract

Abstract Disclosed herein is a method of labeling room temperature vulcanizable silicone polymers at the "T" junction branch points by utilizing cross-linkers of the formula D-SiX3, wherein X is a leaving group and D- is a complex organic molecule useful as a dye, fluorophore, or indicator.
