Abstract
The purpose of this study was to evaluate a reactive fluorescent probe, 9,10-Bis-(phenylethynyl) anthracene (BPEA), for cure monitoring of hydrosilation-curable silicones. The hydrosilation-curable silicone consisted of a vinyl terminated polydimethylsiloxane prepolymer (74.9 % in mass fraction), a methylhydrosiloxane-dimethylsiloxane copolymer (molar mass of 2,000 g/mol, 25.0 % in mass fraction) and 1,3-divinyltetramethyldisiloxane (0.1 % in mass fraction) as an inhibitor. The catalyst consisted of the same vinyl terminated polydimethylsiloxane prepolymer used to make the hydrosilation-curable silicone (99.7 % in mass fraction), the same vinyl terminated polydimethylsiloxane prepolymer (0.3 % in mass fraction) containing a platinum catalyst at the mass fraction of 3.5 %, and the reactive fluorescent probe BPEA at a dopant level. Three hydrosilation-curable silicones (hereafter referred to as Silicones L, M, and H) containing vinyl terminated polydimethylsiloxane prepolymers, which wereCitation
