Features & Benefits

Labeling Claims
Features
  • Free of formaldehyde.
  • No migration in PVC.
  • No basic Rhodamines.
  • Low bleeding in most solvents.
  • For aqueous formulations, the use of preservatives is highly recommended. The right preservative package (combination of bactericides and fungicides) should provide reliable, highly effective control of microorganisms in the intended formulation.
  • Limited lightfastness in exterior exposure due to the chemical structure of the fluorescent pigments.

Applications & Uses

Applications
  • Flexible PVC, solvent based paints, gravure inks.
Processing
  • Heat stability - In PVC calendering: 30 minutes @ 170°
  • Solvent resistance - Recommended use in water, esters, ketones, aromatic solvents, isopropanol. Can’t be used in alcohols.
  • Pigments are insoluble and need to be dispersed (easily stir-in).
