Why ECLEAR® dual-cure hardcoating technology is unique

February 27,2016.

Traditional PC trolley suitcases are of matte finish to make less visible the scratch lines or stains from everyday use.  ECLEAR® dual-cure hardcoating technology has now made shiny and anti-graffiti PC suitcase possible. The cured hardcoat exhibits excellent optical clarity, impact resistance and a high-level glossiness, and could even be abrasion resistant to wire wool. This result in an "as new" look of the PC suitcase even after repeated cleaning and handling---the most easy-to-clean PC suitcase in the marekt!

ECLEAR® dual-cure hardcoating technology is world's first successful attempt combining the heat & UV in optical hardcoat curing process. It offers more design flexibility for thermoformable PC and PMMA substrate materials. The intended substrate materials could be hardcoated and pre-cured by heat first, thermoformed to desired shape afterwards and then put for final UV curing. The cured coating delivers excellent optical clarity and abrasion resistance. 

Typical application on PC suitcase: extruded PC sheet---flow coating on the PC sheet---preheat till tack free (pre-cured @ 80℃ for at least 5 minutes)—mask the coated PC sheet with protective film---thermoformed to desired shape---UV cure (post-cured)---CNC processing
