About This Product
Combined with a clear binder such as an acrylic base, the pigment can be used for UV-warning samples, smart graphics, packaging examples and garment-design work. Brush painting, block printing, stencilling and screen printing all suit it, and a 50:50 mix with the binder is a practical place to start.
