Title: Innovations of Thomas E. Gray

Introduction

Thomas E. Gray is a notable inventor based in Midland, MI (US), recognized for his contributions to the field of organopolysiloxane compositions. With a total of 5 patents to his name, Gray has made significant advancements in silicone elastomers and their applications.

Latest Patents

One of Gray's latest patents is a method for preparing organopolysiloxane bases and compositions therefrom. This innovative method allows for the creation of organopolysiloxane bases with high levels of fillers by mixing components at temperatures below about 60 degrees Celsius. This process results in a homogeneous blend that can be further combined with a platinum group metal-containing catalyst and other components to form a curable liquid silicone rubber (LSR) composition. The improved flow characteristics of this composition enable the incorporation of larger quantities of fillers while maintaining acceptable flow properties. Additionally, the silicone elastomers produced exhibit enhanced resistance to oils, lower compression set values, and improved mechanical properties without requiring post-curing.

Another significant patent by Gray involves curable organopolysiloxane compositions with improved adhesion. These compositions cure through the addition reaction of silicon-bonded lower alkenyl radicals with silicon-bonded hydrogen atoms. They include an adhesion-promoting mixture that enhances adhesion to various substrates, comprising an epoxy-functional compound and other specific components. Notably, the compression set of the cured compositions remains largely unaffected by the adhesion-promoting mixture.
