Media Matte Medium is an acrylic medium that allows you to change the properties of Media Fluid Acrylics and increase the number of ways they can be used. Its most common use is to increase the transparency and thickness of the paint. It will add translucency to the more opaque colors, and will make the very translucent colors more opaque.
