Enhanced properties of coil coated steel can be realised by the
introduction of alternative curing technologies such as electron beam,
ultraviolet light and near infrared radiation. Fully non-volatile
formulations, applied and cured in a few seconds allow for the
enhancement of a manifold of desirable properties. Extreme hardness in
combination with good flexibility, effective barriers towards aggressive
environment, aesthetic appeal as well as almost any functional surface
is plausible assets of future coil coatings. Particularly, exterior
coatings that endure long wet times and extended periods of solar
radiation as well as attractive and functional surfaces that break ways
into new applications of pre-coated steel are highly interesting.
Benefits of combining thermal and UV-curing formulations in a multilayer
coating product and examples of enhanced properties as well as the long
term, exterior durability of such systems will be discussed. |
