UV CURABLE POWDER COATING
UV
curable powder coatings are now commercial applied at several industrial
coating lines. UV curable powder system can be applicable to pre assembled
metal substrates and MDF ( Medium Density Fibre board). The UV powder system
is attractive because it combines the environmental and technical advantages
of powder coatings and
UV curing. The manufacturing and application of the UV curable powder coatings
is equivalent to conventional thermal curable powder coatings due to absence
of solvents. The curing of the UV powder coating however is initiated by
exposure to UV light and consequently the curing temperature can be much
lower compared to conventional powder coating.
Similar
to conventional powder coatings the resin system used and the use of additives
affect the final properties of the coatings. Also the parameters of UV curing
can have a strong impact on the final coating performance, comparable to
the temperature time curing window of conventional powder coatings. Variables
in the curing process of the UV powder formulation are primature like temperature
amount of UV-light , energy of
UV light and the spectral output of the lamp.
