Product detailed description

Swedish linseed oil against corrosion

• For the treatment of iron and steel - new and corroded surfaces
• It is applied by painting, spraying or oil quenching
• Fast drying oil - 1 day drying at 20 °C and good ventilation
• Resistant to grease, petroleum products, salts and household acids (e.g. vinegar, wine, lemon)
• Does not have the problems of conventional linseed oils - does not react with water, completely dries

Rostskyddsolja linseed oil creates a water-repellent layer. The oil molecules are very small and penetrate the surface of the metal and the rust pores. Reacting with oxygen, the oil dries quickly to form linoxin, a natural polymer with good adhesion that prevents further corrosion. It is non-biodegradable, water repellent and resistant to grease, petroleum products, salts and household acids, e.g. lemon, wine, vinegar.

Rostskyddsolja linseed oil protects metal against corrosion better than ordinary linseed oil, which contains components that react with water. The waxes contained in flaxseeds form a gel when they come into contact with water, while the non-drying fatty acids form an emulsion with water. Therefore, with ordinary linseed oil, water can get under the oil layer and cause further corrosion. Traditionally, a method called oil quenching has tried to prevent this problem. The workpiece turned red hot and then dipped into linseed oil, causing a small explosion and the workpiece to turn black.

But SELDER has solved this problem of linseed oil by removing all the substances from it except the unsaturated fatty acids, which are further cooked. The result is a linseed fermé in which no micro-organisms can survive, it does not react with water, dries completely and penetrates deeply into the surface. Anti-corrosive linseed oil cannot be scraped off the metal. The only way to remove it is to soak the workpiece in a strong alkaline cleaner.

Rostskyddsolja linseed oil makes an excellent base for the next coat, provided you have removed the excess oil from the surface before it dries. New, uncorroded metals can be protected against corrosion directly with SELDER oil paints.

How to use linseed anti-corrosive oil

• Remove flaking rust, paint residue, grease, lichen, algae and other dirt. You can tan the surface to loosen the flaking parts so you can easily sand them with a wire brush. You don't have to remove the rust that doesn't peel off because the oil soaks into it.
• Never use alkaline cleaners to clean the workpiece, as they dissolve linseed oil.
• Apply anti-corrosive linseed oil with a brush or spray it onto a dry surface. Apply the oil at temperatures above 5 °C.
• After 30-60 minutes, wipe off any residual oil, otherwise a sticky film will form on the surface. Dry wiping is especially necessary if you are going to paint the workpiece further.
• At 20 °C and sufficient ventilation, the anti-corrosion oil dries in about one day.

For the application of SELDER linseed oil, you can also use the traditional method of oil quenching. Heat the workpiece to ore. Wait until it cools slightly (it will no longer glow red) and immediately dip it in linseed oil. You don't need to heat the oil. Workpieces hardened in SELDER linseed oil will turn brown, whereas conventional linseed oils will turn black. This method is very effective because the oil penetrates the hot iron or steel better. You can also try a light oil hardening option, where you heat the workpiece in the oven to 275 °C and immerse it in oil.

SELDER linseed oil does not contain any solvents, drying agents or other additives. It achieves its unique properties through a refining method that removes all the components that cause problems in conventional linseed oils for wood.

SELDER flaxseed oils bust myths about flaxseed oils and ferments

• Short drying time: Regular oil takes a long time to dry and is recommended to be applied in thin layers. - SELDER has solved the problem by removing the antioxidants. SELDER linseed oils dry quickly (1 day at 20 °C), even without the addition of driers.
• No permanent yellowing: Linseed oil contains beta-carotene, which causes painted wood to turn yellow over time. - SELDER has solved the problem of permanent yellowing by removing the beta-carotene. However, the oils are photochromic, i.e. they turn yellow in the dark and fade again in the light within a few hours.
• No chalking of painta: Normal linseed oils tend to chalk and form white spots on the surface on contact with water. - SELDER has solved the problem by removing the saturated fatty acids (stearic and palmitic) and wax.
• No fungicides: Linseed oil alone does not protect against rot, so it must contain fungicides - SELDER protects wood against rot naturally by forming a water-repellent film on the surface. In addition, nutrients for wood-destroying microorganisms (e.g. proteins and saturated fatty acids) have been removed from SELDER oils.
• Solvent and dryer free: Conventional linseed oils contain solvents for better spreadability and driers for fast drying - SELDER produces pure linseed oil without additives. It undergoes a unique refining method and is then boiled in various ways to achieve the optimum viscosity for a variety of uses. The flax fermé is used for various coatings, from wood impregnation to corrosion protection of metals. See the complete SELDER oil range .
