Linseed oil - GOST , variety and use of equipment

Behavior varnish and a brief description

Drying - a film-forming liquid substance on the basis of vegetable oils with the addition of solvents and alkyd resins.Driers that make up the varnish, accelerate the process of drying.Linseed oil, which is a quality certificate confirming compliance with the technology in its production, is used for impregnating the protective metal or wooden surfaces, which will later be painted with oil paint, but also plays a role of a connecting element in the manufacture of oil-based paints or breeding.

After applying the composition on the film surface occurs, which hardens after drying, and forms a protective layer.The main indicators of the quality of linseed oil is its viscosity and drying speed.The higher the viscosity, the harder it is to distribute the composition evenly over the surface.

Species

varnish drying oil production is characterized by the use of drying oils: linseed, hemp, walnut, poppy.The main component - linseed oil, the remaining oil is added, as a rule, for its cheaper.

There are three types of drying oil: oil, alkyd, composite or synthetic.The oil, in turn, also can be of three types: natural, combined and Oksol .

They differ among themselves to different percentages of components, which affects their appearance, density, smell, but not on the protective properties. Natural linseed oil is made up of vegetable oils and does not contain solvents, which makes it environmentally friendly, but also expensive.It is widely used in everyday life, because virtually odorless and does not emit harmful substances to humans.

alkyd linseed oil, technical specifications which do not differ from the oil consists of alkyd resins, which are dissolved in the modified oils and solvents.This substance is a member of the oil or alkyd paint.It is very resistant to weathering and is used for a long time, so it is recommended to use it for outdoor use.

synthetic drying oil, the characteristics of which differ from those of other species, based on artificial substitutes of natural products.Often, this refined products, so it is very toxic.Since even for several years, it continues to produce harmful substances, then a drying oil used for exterior painting or well-ventilated non-residential premises.

technique of using linseed oil and precautions

Before using the varnish, it must be thoroughly mixed.When thickening can be diluted with solvent or nephras.Apply it on the dry and clean surface at ambient temperature not below +5 ° C.Since it can be applied by brush or roller, or spray gun, the drying oil consumption will depend on the method of application.

It is worth remembering that the linseed oil - it is flammable and explosive substance because of the presence of solvents in its composition, so the room where operations should be well ventilated.Skin needs to be wiped with a cloth, then rinse with warm water.Keep it needed in a tightly closed container, protected from moisture and direct sunlight, away from open flames and electrical equipment.
