The process of 'dry' drying oils such as occurs due to evaporation of the solvent, and as a result of interaction processes oils with oxygen. Combined varnish marks R3, R5 designed for the manufacture of paints for interior and exterior. Combined varnish brands K2, K4, K12, K11, paint, used only for internal operations. Linseed oil 'Oksol B' is used for dilution to a viscosity of oil-based paints gustotertyh MF only for internal operations. LMS (polymerized linseed oil) is a natural substitute for linseed oil and is used for both domestic and for exterior colors.
Gliftalievaya linseed oil is made from vegetable oil, glycerine, etc. of the solvent content of no more than 50%. Pentaphthalic linseed oil is also made from an alkyd resin. Artificial drying oils (synthol, karbonol, etc.) do not contain any oils at all, or in small quantities. As for the quality they are far inferior to natural drying oil and oksolem.
Alkyd varnish – are solutions of alkyd resin modified oils. They are glyptal, pentaphthalic and ksiftalevye. By the way linseed oil are the so-called artificial drying oils, including oil-free products based on the polymerization of petroleum hydrocarbons, oil shale, and fish oils etc. Thus, oil paints are a mixture of pigments, fillers (talc, barium sulfate, barite) and linseed oil. State Standards issued by oil paints the following brands (depending on the type of film-forming substance): MA-021 – for natural drying oil; MA-025 – on a combined drying oil, GF-023 – on glyptal drying oil, PF-024 – on pentaphthalic drying oil. The number 2 indicates that the paint, varnish diluted appropriate, be used on any surface. Ready to eat paint hit the market are packed in containers of 0.5-3 liters. The labels stated purpose of paint, color, flow rate at 1 m surface with single and double layer coatings used thinners, etc. Should strictly adhere to these guidelines.
