ABSTRACT:
A method is for curing ultraviolet light-curable coatings, inks or adhesives on heat sensitive substrates, wherein the substrates are coated and then passed under ultraviolet light. It includes reducing the temperatures of the substrates while being passed under the ultraviolet light by providing a shield at a location between the ultraviolet light and the substrates. The shield is substantially infrared light reflective and absorptive to prevent infrared light from reaching the substrates and is also substantially ultraviolet light permeable to permit ultraviolet light to reach the substrates. An ultraviolet light curing device utilizing the aforesaid shield is also described for curing ultraviolet light-curable coatings, printings and adhesives on heat sensitive substrates.
