Product brochure
Fluorescent pigments absorb part of the light, including UV, and emit it back at a longer wavelength close to their own hue. That extra emission makes them brighter than any conventional pigment. They show best over a white ground and lose punch when mixed with off-shades. The brochure lists five series, HK, HP, HT, HW and HX, with heat resistance grades stated from 160°C up to 250°C and 280°C.

Solvent and general purpose
Bright grades for printing and screen inks, paints and general coloring, where the white ground and the shade matter more than process temperature.
Aqueous · custom matches
Grades for aqueous binders and specialty uses, in any shade on the card. Where the card falls short, the division makes a custom match from the sample you send.
Buying it right
Safety marking, high visibility parts and warning labels lean on orange fluorescent. The color must stand out in daylight, and it fails if it dulls in processing.
Transcor offers three orange shades on its card, Orange Yellow, Orange and Orange Red, across series for plastics, inks, coatings and water based systems.
Choose the series by your process temperature. When the card shades fall short of your standard, the pigment division matches the orange from your sample.
The partnership
