Metallic Effect Pigment

Metallic effect pigments outdated, bronzes are platelet-shaped, metallic pigments. The optical effect of these effect pigments based on orientation of the flakes parallel to the surface of the surrounding system in which a directed reflection occurs. They are in the Colour Index under CI Pigment Metal listed. Metallic effect pigments are used for producing metallic effects in coatings , printing, plastics and cosmetics used. The economically most important aluminium.

Daylight pigments

Multi-purpose pigments for use in a wide range of fields. Typical applications are coatings for ambulances, fire brigade, signs, billboards, etc. This series is further excellent for spray coatings. Aerosols for use in forest and road markings are becoming increasingly important. Another area is the coloring of plastic coatings and calindered soft PVC films.

Photoluminescent Pigment

All our photoluminescent pigments are based on strontium aluminate, they are non-toxic,harmless and non-radioactive. Compared to the traditional Zinc Sulfide photoluminescent pigments, the luminosity strontiumaluminate pigments is at least 10 times as higher as it and the afterglow time is also at least 10 times as longer as it. Our photoluminescent pigments can be added into many different transparent medium, such as ink, paint, plastic, cer amic, glass, etc.

Optical Brightening Agent

Optical brighteners need for their action ultraviolet radiation . Especially with strong sun and clear blue sky in the open or under suitable artificial lighting (with a high UV percentage) the White acts then white. Fluorescence is the cause of the whitening effect of the optical brightener. These are substances from the invisible ultraviolet (at 290-400 nm) absorbing and most of the absorbed energy in the visible light after intramolecular interlude emit.

Unlike pigments, dyes dissolve completely in the medium used. The familiarization is usually easy, because the fine distribution step (dispersion) is omitted.
