Abstract

This invention relates to fusing devices for use in electrostatographic copying machines. It is known to use either HTV (high temperature vulcanizable) silicone elastomers or RTV (room temperature vulcanizable) silicone elastomers as the material for forming the covering on a fusing device. The HTV silicones have the advantages of high strength and lower processing costs. However, the HTV silicones have poor life expectancies, which has been attributed to poor polymer bonding to certain fillers, especially to those fillers added to improve thermal conductivity, and poor adhesion to substrates.
