Abstract

Elastomeric components, such as a shoe outsole, are treated with a plasma application to clean and activate the elastomeric component. The application of plasma is controlled to achieve a sufficient surface composition change to enhance adhesion characteristics while not adversely physically deforming the elastomeric component. The plasma treatment is applied to increase carbonyl functional group concentrations within an altered region of the elastomeric component to within at least a range of 2%-15% of carbon atomic percentage composition. The cleaning and activation is controlled, in part, by ensuring a defined height offset range is maintained between the elastomeric component and the plasma source by a generated tool path. The elastomeric component may then be adhered, with an adhesive, to another component.
