Dual-cure Automatic Hardcoating Line for Helmet Visor

Conventional heat-curable HC solution will usually require 120 minutes curing time @ 120 Celsius for PC (80 Celsius for PMMA). That will make the coating job a time-consuming process. For our proprietary dual-cure resin solution, once applied, the coating will undergo a pre-heat treatment for precuring @ 80℃ for 5 minutes so that a tack-free (visor) lens surface could be obtained (solvent flash-off), then the coated (visor) lens will be moved to UV curing unit for post-curing process which will help achieve full crosslinking of the resin (UV radiation dose @ 800mj/cm²).
