Abstract (en)

[origin: EP1002587A2] A crosslinking reaction is initiated in a reactive paint formulation. This is coated-onto a surface at least locally, before reaction is completed. Independent claims are included for equipment carrying out the process, and for the coating so produced. The equipment employs a sprayer and/or electrostatic applicator with bell housing. Preferred features: Initiation of reaction preferably employs UV illumination (1), in conjunction with at least one photoinitiator in the formulation. Kinetics of the reaction are controlled by temperature variation, and/or by use of a sufficiently slowly-running reaction, especially a cationic polymerization, and/or by spatial separation of photoinitiator(s) from the formulation components and/or by minimizing reactivity of the photoinitiator(s). Spatial separation cited, is by nano-structuring of the paint formulation. Further stages include mixing a UV protection agent and/or pigment into the formulation before coating. A hand spray gun (6) applies the paint. In the equipment, optical fibers (3, 4) transmit UV light to the paint formulation.
