That is great the results are good so far.
Yes we can integrate optical brigthener
to optimize the result (show less yellowing).
Disatvantage is that you can see maybe the optical
brightener under UV black light and higher price.
Another possible optimization ist to use less UV energy
during the coating process.
The machine of Alupact is relative slow. Our coating
is high reactive, so they can reduce the energy of the
UV system.
They can test the curing with acetone and scratching.
Because too much energy cause overcuring and
yellowing of UV coatings.
Another advatage is that they save energy.
Do you have someting left of UV 1-33/54 A?
Maybe we can test in August.
Should we formulate a version with optical brightener now
or after visit, what do you think?
