Abstract:
A method for coating a surface with an ultraviolet (UV) or electron bean curable coating comprising:providing a coater apparatus cloning a housing having a top wall, side walls attached to the top wall and an open bottom defining a first compartment and a second compartment, a partition wall attached to the top wall between the first compartment and the second compartment for separating the first compartment from the second compartment and for minimizing reflection of curing energy from the coated surface, a coater selected from spray and roll coaters disposed in the first compartment, a curing energy source selected from ultraviolet and electron beam energy sources disposed in the second compartment, wheels rollers rotably attained to the side walls on a lower potion of the housing for moving the housing across the surface during a coating operation and for maintaining a gap between the housing walls and the surface to be coated, and a control unit attached to the housing or remote from the housing for controlling the coater and energy source during a coating and curing operation;applying the UV or electron beam curable coating to the surface by means of the coater apparatus;and curing the coating using the ultraviolet or electron beam energy source while moving the coater apparatus across the surface and while minimizing the reflection of curing energy from the coated surface to the first compartment.
