Precise coating and slitting techniques allow Lamart to apply conductive primers on thin foil substrates that are used as current collectors in batteries. In line treatment of these materials eliminates, or greatly reduces, surface contamination, which enables better coating adhesion and increased product yields. Because of the demanding requirements of these processes, Lamart's customers normally specify which materials will be used.

  • Priming of Thin Foils

Hard (H-19) aluminum foil and ED copper foil as thin as 0.0007" (17.8 microns) are primed and slit using Lamart's precision manufacturing equipment. Sensitive web handling techniques minimize stress on the foil during processing to maximum yields. 


Lamart has designed processes to make laminated and coated structures used in the manufacturing of fuel cells and solar collectors. We work closely with our customers to understand their specific needs, then decide how to develop the processes and products that work best with their particular technologies. Lamart's 13" (330mm) wide lab coater, with 25 foot (7.6m), 3 zone drying oven, can be used to coat catalyst slurries on a carbon substrate to make gas diffusion layers - GDL - or to laminate GDLs to membrane electrode assemblies - MEA.
