Dyes of the OWI®SOL series

Unlike pigments, dyes dissolve completely in the medium used. Incorporation is usually problem-free, since the fine distribution step (dispersion) is omitted.

Pearlescent pigments of the OWI®PEARL series

Wilhelmi Color’s natural MiCa (mica) pearlescent pigment is made from natural mica.

Fluorescent pigments from the Brilliant®

Fluorescent daylight colors make products more visible and attractive.

Organic Pigments
of the OWI®PLAST, OWI®PAINT and OWI®INK series

Pigments are (largely) colored or achromatic colorants, organic or inorganic in nature, which are present in the medium to be colored with measurable particle size.

UV absorbers / HALS of the OWI®SORB series

UV absorbers / HALS are substances that protect organisms or technical products from the damaging influence of light, especially UV radiation.

Optical brighteners of the OWI®Bright series

Optical brighteners require ultraviolet radiation for their effect. Particularly in strong sunshine and clear blue skies outdoors or under suitable artificial lighting (with a high UV content), the white then appears whiter.
