In the automotive industry, the technology (3M Paint Replacement Film) eliminated the need for paint on door pillars, window sashes, and other body trim. When combined with high-performance abrasives and fasteners, the micro replication technology enabled diapers to hold more securely and comfortably. It was also used to create channels that directed fluids across a surface using capillary action as in biotechnology products.
