Naval Surface Warfare Center, Carderock Division has an ongoing project funded through the Office of Naval Research to develop a novel, corrosion-resistant poly(styrene-co-catechol) tie coat and adhesion promoter to improve CARC adhesion and performance to various composites, aluminum, and steel USMC ground vehicle surfaces.
Interfacial chemistry plays a significant role when working with coatings, specifically the surface tension (SFT) of liquids and the surface free energy (SFE) of solids. These parameters are often measured or calculated in order to optimize the adhesion properties and obtain long-lasting adhesion that will inhibit delamination and adhesion failures.
For manufacturers that utilize flat-rolled steel, aluminum and other metals to fabricate parts or products, the ability to bond decorative foils and laminate films to the substrate provides an opportunity to deliver attractive finishes for a competitive edge.
It is concluded that for coating applications in medical devices, microcratch and nanoscratch are useful and quantitative approaches for examining coating-to-substrate adhesions.
The present study will demonstrate the utility of aqueous dispersions of functionalized low-molecular-weight hydrocarbon polymers as a formulating tool to develop improved surface treatments for rubber-to-substrate adhesion.
