- Product Highlights
DayGlo® VC-Pigments have exceptional brightness, high tinctorial strength, are translucent, and possess excellent heat stability; surpassing melamine-formaldehyde pigments in these characteristics. VC-Pigments are vinyl based and recommended for calendered, extruded and injection molded vinyl.
- Stabilizer
VC-Pigments do not have any lead or cadmium containing stabilizer.

- Applications
VC-Pigments are recommended for rigid and plasticized PVC. They do not cause buildup on calendering or two roll mill equipment and have a low degree of plateout on metal surfaces of processing equipment. The typical use rate is 1 – 3% pigment by weight.
- Typical Formulations
3% of vinyl colorant by total weight of vinyl compound or resin is recommended as a starting point.

Technical Details & Test Data
- Transparency
VC-Pigments were designed for maximum transparency and offer excellent edge glow. For opacity, TiO2 can be added at a ratio of 3:1 - VC-Pigment:TiO2. Small amounts of TiO2 may be necessary in transparent resins to increase the fluorescent effect.
- Heat Stability
VC-Pigments display no color change after a heat history of 20 minutes at 350oF (175oC) on a two roll mill. For injection molding, it is recommended that the pigment be converted into pellet form in order to minimize sifting, packing and potential burn-out.
- Lightfastness
The higher the pigment concentration, the better the lightfastness. The lightfastness can be influenced by plasticizers, stabilizers, and other additives. At a concentration of 3%, VC-Pigments exhibit better lightfastness than other organic fluorescent pigments tested in an Atlas Xenon Arc Weatherometer.
- Bleeding
Bleeding that occurs when using VC-Pigments is greatly influenced by the amount of plasticizer used in the vinyl formulation. The tendency to bleed can be reduced by using lower amounts and/or higher molecular weight plasticizers.
