Title: Eugene E. Harkins: Innovator in Polymer Processing and Coating Technologies

Introduction: Eugene E. Harkins, based in Vadnais Heights, Minnesota, is a distinguished inventor credited with two patents that significantly advance the fields of polymer processing and coating technologies. His innovative contributions have enhanced efficiency and effectiveness in industrial applications, particularly within the context of continuous extraction processes and electrospray coating methods.

Latest Patents: Harkins' latest innovations encompass a method for removing impurities from polymers and a specialized electrospray coating apparatus. The first patent presents a continuous, preferably counter-current extraction process designed to reduce the presence of residual monomers, catalysts, solvents, and other impurities within polymer compositions. This technology is especially advantageous for treating viscous polymer solutions, such as Pressure-Sensitive Adhesives (PSAs) and low cohesive strength polymer compositions that undergo phase changes during extraction. By enabling the extrusion of polymer compositions into an extraction solvent in a vertical column, Harkins' process efficiently extracts impurities while maintaining the integrity of the polymer materials.

His second patent focuses on an electrospray coating head system that applies thin coatings to substrates with exceptional precision. The apparatus features a slot or blade that meters liquid onto a shaping structure, ensuring that the liquid maintains a consistent radius of curvature. The application of voltage to the liquid prompts the formation of a series of filaments that create a uniform mist of charged droplets. This method not only streamlines the coating process but also enhances the overall quality of the applied layers.

Career Highlights: Harkins has made notable contributions while working with renowned firms, including the Minnesota Mining and Manufacturing Company and 3M Innovative Properties Company. His career at these organizations has allowed him to innovate within the materials science and coating sectors, demonstrating a commitment to enhancing industrial processes and product quality through his inventions.

Collaborations: Throughout his career, Harkins has collaborated with esteemed inventors, including his coworkers, Albert E. Seaver and William R. Berggren. These professional partnerships have played a significant role in the development and refinement of his patented technologies, underscoring the collaborative spirit that drives innovation in the field.

Conclusion: Eugene E. Harkins represents a vibrant force in the realm of polymer technology and coating processes. With a focus on developing methods that improve efficiency and quality, his patents reflect a dedication to innovation that contributes to the advancement of industrial applications. As he continues to inspire future generations of inventors, Harkins' work serves as a testament to the critical role of creativity and collaboration in driving technological progress.
