Converters Turn to Slot-Die Coaters to Increase Quality, Reduce Emissions

One reason for the increased attractiveness of slot-die coating is that the intense competition generated by industry consolidation and globalization has increased pressure to maximize economy, productivity and quality assurance. Quality is especially critical in medical, electronic, photographic and other high-end markets. At the same time, there is a growing mandate for further reductions in emissions of volatile organic compounds (VOCs) from solventborne coating systems.

The slot-coating die differs from the roll coater in two critical respects:
