Rastvoriteli, thinners, sikkativyi

At fulfilment of painting works diverse auxiliary materials be required: solvents, thinners, sikkativyi, shpatlevki, first coats, podmazki etc.

Solvents are the organic flying liquids applied to giving to painting structures of a necessary painting consistence. Depending on appointment they are divided into solvents: for oil paints - petrol, uajt-spirit, turpentine; for gliftalevyih and bitumen varnishes and paints - solvent-nafta, turpentine, ksilol; for perhlorvinilovyih paints - acetone. For glutinous and vodnoispersionnyih paints solvent and a thinner is water. For household needs the combined solvents (the number are manufactured also: 645-651; RS-2, R-4, R-5, R-12, RP). The majority of solvents - hydrocarbonic organic flying liquids, combustible and explosive.

Thinners and razzhizhiteli unlike solvents have no dissolving ability and serve for viscosity reduction gustotertyih paints or cultivation of dry mineral paints-pigments. As thinners drying oils and various emulsii are used. Hardly thickened first coats, paints or varnishes at first plant with solvent, maintain 3-4 hours then lead up to the necessary consistence a thinner or razzhizhitelem. Thus their quantity in a paint and varnish material should not exceed 5 %, loss of pitch and material damage differently is possible.

Solvents and thinners apply also to clearing of old covers of pollution, removal of the rests of organic greasings and pollution from unpainted surfaces, washing of brushes shpateley and other tools.

At work with solvents it is necessary to remember, that concentration in air of their steams at long inhalation can cause dizziness and even a faint. Use of solvents for washing of hands leads to skin diseases. Number of the most harmful solvents concern benzene, dihloretan, methyl spirit, trihloretilen, hlorbenzol.

Sikkativami name connection of metals (basically lead, manganese, cobalt, calcium, iron) with organic acids. Them add in number of 5-8 % on weight to drying oils both oil varnishes and paints for acceleration of drying of their films. Surplus sikkativa accelerates drying, but does a film fragile and can lead to cover presenilation.

Quality sikkativa evaluate on the metal entering into its structure. The best properties have cobalt (NF-4 and NF-5) and manganous (NF-3) sikkativyi.

Drying oils ready to application, paints, varnishes, enamels, as a rule, contain the necessary quantity sikkativa, therefore to add it in such materials there is no necessity. It is not necessary to enter sikkativyi in spirit varnishes, nitrocellulose materials, paints emulsionnogo type, paints and varnishes on the basis of bitumens and pitches and other materials which are not containing oils.

Retention period sikkativov - 6 months. As a result of long storage they can become muddy and unsuitable to application Source: PROEKTSTROY.RU
