Title: Innovations of Loretta N Kroupa
Introduction
Loretta N Kroupa is a notable inventor based in Midland, MI (US). She has made significant contributions to the field of adhesive and silicone compositions, holding a total of 3 patents. Her work has advanced the technology behind flexible adhesives and electrically conductive silicone materials.
Latest Patents
One of her latest patents is for optically clear organosiloxane adhesive compositions. This invention involves liquid organosiloxane compositions that cure through a hydrosilylation reaction. These compositions contain from 0.1 to about 2 weight percent of a low molecular weight polymethylvinylsiloxane cure, which forms adhesives that maintain cohesive bonding between substrates with different coefficients of thermal expansion. This is particularly important when the resulting composite is exposed to temperature variations during use. The flexibility of the cured adhesive is enhanced by adding a liquid polydimethylsiloxane with specific terminal groups.
Another significant patent is for electrically conductive silicone compositions. This invention improves the electrical conductivity of polydiorganosiloxane by incorporating conductive carbon particles. The enhanced conductivity is achieved through the addition of a conductivity improver, which is a disilazane with a specific chemical formula. This innovation has important applications in various electronic and industrial fields.
