SILICONE HARDCOATING AND PLASTIC HEADLAMP LENSES WERE FIRST DEVELOPED IN THE LATE 1970S DUE TO THE GROWING TREND IN AUTOMOBILE DESIGN TOWARDS WEIGHT REDUCTION AS WELL AS A DESIRE FOR DESIGN FLEXIBILITY. GENERAL ELECTRIC'S LEXAN POLYCARBONATE COATED WITH GENERAL ELECTRIC'S ADVANCED PRIMER AND SILICONE HARDCOAT COMBINATION QUALIFIED AS A PERFECT REPLACEMENT FOR GLASS AUTOMOTIVE HEADLIGHTS. VACUMET INCORPORATED IN CONJUNCTION WITH GE FIRST DEVELOPED THE PROCESS ENGINEERING SPECIFICATIONS FOR HARDCOAT APPLICATIONS ON FORD AERODYNAMIC HEADLAMP LENSES.
