Tri-Art High Viscosity Acrylics deliver professional-grade pigmentation in a phosphorescent formulation designed for artists seeking luminous, glow-in-the-dark effects. These 60ml tubes feature the brand's signature high-viscosity consistency, offering excellent paint retention and dimensional brushwork without excessive flow. Series 8 phosphorescent colors maintain their vibrant intensity under UV light and in darkness, making them ideal for mixed-media installations, theatrical applications, and fine art pieces requiring dramatic visual impact. The thick, buttery formula resists settling and provides superior coverage, while the generous tube size supports both studio work and educational settings. Compatible with standard acrylic mediums and varnishes, these tubes integrate seamlessly into existing workflows for painters and mixed-media artists.
