UV curable pigmented systems: available photoinitiators and current trends

By Giuseppe Li Bassi, Fratelli Lamberti S.p.A.

Pigmented coatings and filled or reinforced plastic systems are very widely used for functional and decorative purposes. The possibility to enter these fields with 1W curing technology offers many practical advantages.

The proper choice of the photoinitiators combination which meets the right wavelength emissions is the key point to be fulfilled.

Significative examples with different matrixes in various applicative areas illustrate the potentiality of the commercial available solutions, while the current trends in the industrial research are pointed out.
