Siloxanes, renowned for their heat resistance and release properties, are prone to oxidize above 200°C. The goal herein is to increase siloxane bath life used in fuser roll applications at temperatures above 200°C, yielding faster production, less waste, and cost savings by keeping the bath viscosity stable through prevention of thermal degradation.
The methods detailed herein react a hydrosiloxane with an amino functional alcohol (4-(phenylamino)-phenol). The alcoholysis (or dehydrogenative coupling) moves forward with the removal of hydrogen and formation of the desired product (Scheme 1). Reactions were conducted on both NMR scale and lab scale.
The results of the synthesis were characterized via NMR spectroscopy and evaluated via heat age studies. The material, confirmed via 29Si NMR, was proven effective through heat age testing in both fluid and elastomer formulations.
