Is Pigment Choice Important When Formulating A LUMIFLON-based Coating?

The superior weatherability of the LUMIFLON resin family has been proven over the years by extensive lab testing and countless exterior structures that have been coated with these products. The LUMIFLON resin component plays a big part in protecting itself and other resin components from the destructive UV rays of the sun. However, this protection has limitations when it comes to protecting the pigments in the formulation. The proper pigment choice will insure good color retention. If it is possible to use inorganic pigments to achieve the target color of your formulation, use them. When choosing organic pigments, choose those pigments that boast a high degree of light fastness. It is important to keep in mind that pigments which are mediocre performers when exposed to sunlight will always be mediocre performers – even in LUMIFLON resin-based formulations. They will still need the help of UV absorbers and hindered amine light stabilizers. The protection from UV degradation courtesy of the LUMIFLON resin for these organic additives has yet to be determined. However, the increased longevity of the coating film will keep these additives from eroding out of the film.
