Vallejo 70540 540 Model Color Matte Medium 189
Matte Medium extends the colors, increases their fluidity and transparence, and softens the blending of brushstrokes. It heightens the flexibility of the colors, and their adhesion to the surface. It is the perfect medium for glazes. Does not yellow or change tonality of the color. Can also be used as a binder for dry pigment. Acrylic Matte Medium has a milky appearance, but dries totally transparent and matte.
