This is a highly viscous, thermal polymerized linseed oil that increases the transparency of Duo Aqua Oil Colors. It produces a leveled, enamel gloss effect with an elastic, durable film when mixed with Duo Aqua Oil Colors or Duo Painting Oil Medium. It can be thinned with water; the resulting milky appearance will become clear when dry. While Duo Stand Linseed Oil may become cloudy over time, its performance is not affected.
