For spirit varnishes dry at room temperature for 15 minutes is sufficient. Lucky on the basis of thermoplastic polymers. Shellac varnish. Shellac is formed by the activity of insects that feed on sap of lacquer tree. Imported mainly from India. Efirotsellyuloznye varnishes - a solution of cellulose ether with the addition of resins and plasticizers in organic solvents. Atsetobutirattsellyuloznye varnishes are prepared on the basis of cellulose atsetobutirata - mixed ester of cellulose with acetic and butyric acids. Lucky, based on chlorine-containing polymers.
For example lacquer XB-784 is a basic part of their pitch perchlorovinyl PSC, which is obtained by chlorination PVC resin to the chlorine content 62-65%. Lucky, based on thermosetting polymers. Alkyd paints - alkyd resin solutions in uaytspirte or in mixtures of xylene or solvent with the addition of driers. For example lacquer PF-170 Polyurethane varnish. The interaction of isocyanates containing two or more reactive groups with compounds having multiple hydroxyl groups, are beginning monouretany, which are then converted into Polyurethanes - High resin. For example parquet lacquer in epoxy varnish film-forming component is a major epoxy resin grades ED - 16 and ED - 20. Varnish - a 10 - 14% solutions of solid resins in ethyl raw spirit. They are used to polish the wood after sanding and priming the surface.
Among the film-forming polymer leading place belongs to the condensation polymer / alkyd (for example, the production company Dulux), urea-melamine-formaldehyde, epoxy, phenol /. Of cellulose esters are used most frequently is nitrocellulose - cellulose ester and nitric acid. Dry nitrocellulose by impact and friction of the heat easily electrified, which can cause sparks and cause it to ignite and explode. Therefore, when working with nitrocellulose should carefully observe fire safety rules. Nitro lacquer - are solutions of nitrocellulose in volatile solvents with the addition of resins and plasticizers. They are characterized by high weather resistance, transparency, the ability of ground and polished. Nitro lacquer are used for painting walls in special clinics and other health facilities. Bituminous varnishes are solutions of resin and bitumen in a volatile solvent. The approximate composition of these coatings: resin light 20%, bitumen - 45% solvent - 35%. The films of black lacquer and have a high gloss. These water-resistant coatings, but are not suitable for exterior coatings due to lack of weather resistance, corrosion resistance have. Apply for painting metal surfaces. Coal varnish, also called the pitch or varnish kuzbaslakom represent a solution of coal tar pitch in solventnafte. This varnish was first proposed in the Kuznetsk coal basin, whence its name. Kuzbaslaka film is high quality: it has high adhesion, water resistant. The shortcomings of the film include a low plasticity and resilience abrupt temperature changes. Coal is a good paint anti-corrosion coating for metal products sanitary equipment. Enamel paint is obtained by grinding dry pigments glyptal, pentaphthalic and other varnishes. In addition to applying the enamel paint and nitroemalevye, ie on the basis of nitro lacquer. Enamel manufacture ready to eat, and when added to them thickening turpentine or white spirit. Enamel paint for painting upotrelyayutsya machinery, appliances, proshpaklevannyh plaster surfaces, etc. Nitroemalevye different paint dries quickly - 15-45 minutes. (V. 24 - 48 hours in oil-based paints). Film slightest has a strong half-mirror shine, and very hard
