HYDR-OIL water-dilutable oil paints. Using water as a solvent eliminates the need to dilute the paint with harmful solvents commonly used in oil painting, and also eliminates the problem of unpleasant odors, which are particularly noticeable when working in enclosed and poorly ventilated spaces. An undeniable advantage is the low cost and availability of the “solvent”—all you need to do is turn on the tap. The consistency and properties are typical of oil paints, as they consist mainly of vegetable oils, which determine their physical and chromatic properties, such as: a thick and viscous consistency that retains brush or palette knife marks, intense and lightfast colors, almost all of which are opaque, excellent adhesion to all surfaces, even if they are “oily,” flexibility and irreversibility of the paint film after complete drying, and no volumetric shrinkage even in thick layers of applied paint. These paints dry, much like traditional oil paints, through the oxidation of certain bonds within the molecular chains. These linear chains slowly bond with one another through absorbed oxygen, forming a three-dimensional, and thus stable, structure with high light reflectivity, thereby giving the colors a bright and intense appearance typical of oil paints. It is important to remember that even if the colors feel “dry” to the touch after some time—which can range from one to six days (the time varies depending on the thickness and type of substrate)—you should wait at least one or two months before applying any final varnish. HYDR-OIL is compatible with a wide range of auxiliary materials. Dedicated media for Hydr-Oil are listed in the “Painting fluids and auxiliary products” tab.
