Radglo® GM-21

Solid solution of dyestuffs in a thermoset benzoguanamineformaldehyde copolymer. Acts as a fluorescent pigment. It is unique thermoset resin matrix for paint and ink applications where strong solvents are used and for PVC where dye migration occurs with other types of pigments. It is more fugitive than conventional pigments. They are stable to indoor light or outdoor conditions other than direct sunlight. The lightfastness may be improved by including UV– absorber(s) in the formulation and/or by making use of clear overcoats containing UV-absorber (s). Can be used for short dwell times in applications with processing temperatures up to 240°C (masterbatches) without affecting the coloristic properties. Used in solvent based paints and inks.
