Эмаль – это суспензия пигментов с наполнителями в varnishes, which form after completion of the stage of drying a solid opaque film with different textures. It is for these qualities that modern consumers choose these compounds more often than others. In addition, they are able to perform several functions at once, for example, decorate and transform rust. The surface as a result may be moire, matte or glossy. The physical and mechanical properties of the films and the protective characteristics of the enamel are superior to water dispersion and oil paints. Among the main characteristics can be distinguished elasticity and hardness.
As a rule, enamel is a composition that containsa large amount of film former and a small amount of filler. The first ingredient is synthetic lacquer, while the filler has a high decorative effect. Enamels are intended for the formation of the upper layers of the coating, to which there are different and high demands on resistance to the effects of negative factors and decorative. These mixtures are designed to paint metal and wood surfaces, as well as to give them weather resistance and durability. The compositions may have different colors.
Enamel is a composition that can beaerosol, acrylic alkyd or heat resistant. Aerosols differ in that they take very little time to dry. If we are talking about acrylic paints, then they can be used both for interior and exterior work on concrete, wood, brick and plastered surfaces. Alkyd enamels are used to paint different wooden and metal surfaces, namely:
Alkyd enamels can be used both outside and inside the premises. Heat-resistant enamel is a mixture intended for painting radiators that are used at temperatures up to 100 ° C.
Visiting the store, you can find enamels,which are denoted by different abbreviations. For example, enamel, denoted by the letters PF, is a pentaphthalic mixture, which is made on the eponymous varnish. There are on sale GF-enamel, which are called glyptal. Silicon-organic compounds are characterized by high heat resistance, while NC-enamels are made on the basis of nitrocellulose and are characterized by the resistance of surfaces to static action, liquids and industrial oils.
На базе хлорированных, поливинилхлоридных и Alkyd resins are made by XB enamels, which are characterized by excellent weather and chemical resistance and resistance to atmospheric phenomena. On the basis of acrylic made AK-enamel, which have high lightfastness and the ability to maintain whiteness under ultraviolet irradiation. On the basis of alkyd and acrylic are AC-enamels, which have excellent protective properties and the ability to maintain their qualities in a tropical and temperate climate.
На базе алкидной и эпоксидной смол EP-enamels are made, which belong to category B2. This indicates that the mixture can be operated in all zones, except the Far North. On the basis of phenol and oil varnish, FL-enamels are made, which have higher quality characteristics in terms of hardness, drying speed, durability and gloss.
Characteristics of enamels, which you can find inThe instructions on the package make it possible to understand what certain mixtures are for and what technology they should be used for. For example, the enamel mentioned in the subtitle is a coating mixture used to coat old and new radiators, as well as indoor heating pipes. After drying, the surface acquires a glossy shine, and the layer is heat resistant.
The basis is a modified qualityalkyd resin, fillers, temperature resistant pigments, organic solvents and additives. Apply the solution with a brush with natural bristles in one or two layers. After completing the work, tools can be cleaned with a cloth moistened with white spirit, solvent or gasoline.
Such enamels, reviews of which only the mostpositive, dry within 24 hours, this also applies to interlaminar drying. Work should not be started if the thermometer has dropped below +10 ° C. If you have to work with a radiator, the surface of which is cleaned from other coatings to metal, then you should start the work by applying a primer.
Перед использованием вышеописанной эмали it is necessary to prepare a painted surface, for this it needs to be free from dust, dirt, and also rust and moisture. To eliminate rust, you must use a wire brush, chemicals, or sandpaper. Nitrosolvents will allow to get rid of fat pollution.
According to buyers, before applying the enamelshould be well mixed. Application can be carried out by spraying or with a brush. The application of the second layer should be carried out a day after the first. Such enamel, the technical characteristics of which have been mentioned above, can be cleaned on the surface of the radiator. According to users, this can be done no earlier than a month after staining.
Довольно часто в быту возникает необходимость apply enamel on surfaces that were affected by rust. To carry out such work, you can use the enamel mentioned in the subtitle, which is sold in banks of 2.5 kg each. For such a volume of the consumer will have to pay 895 rubles. The color of the solution is silver. Using this mixture, you can transform rust, apply anti-corrosion priming and paint the surface to achieve a decorative effect.
Enamel can be applied for staining inatmospheric conditions, as well as indoors. After drying, the layer acquires a high weather resistance, anti-corrosion resistance and high moisture resistance. This enamel rust forms a kind of coating in the form of a pattern that resembles hand-chased. Then you can get a hammer texture pattern, with which you can disguise minor defects.
It is noteworthy that the single-layer coating dries.within 4 hours, but on tackiness the base will dry in just an hour. The degree of gloss will depend on the tool and method of application. In order to achieve the hammer effect, the application should be carried out in two or three layers. With this you must be prepared that for an area of 5 m2 1 liter of enamel will be needed. With a single layer application, the consumption is reduced to 90 g per m2. You can use this enamel at home.conditions, however this is not all that you need to know before applying. For example, an alkyd component is used as a base, but it is impossible to tint a mixture.
The company "Lacra" offers for sale primer-enamel3 in 1, manufactured on alkyd basis. The composition is able to transform rust, decorate the surface and have an anti-corrosion effect on it. After drying, you get a glossy coating that is resistant to weathering and mechanical stress. The mixture is universal, because it can be used not only for interior but also for outdoor use.
Предназначается эмаль для окрашивания ржавых, clean and partially coded metal surfaces, on the basis of which rust is contained up to 0.1 mm thick. This enamel rust 3 in 1 should be applied to the prepared surface, which should be cleaned of dirt, dust, and loose rust. It is possible to eliminate exfoliating old coatings; if necessary, the surface should be degreased.
If the surface was previously applied oil oralkyd paint, they need to be cleaned to a matte state, and then check for strength and compatibility. To do this, experts recommend a trial staining. If the old coating flakes off, it should be removed. Before using the primer-enamel must be well mixed, if necessary or before painting it is possible to dilute the composition to the working viscosity with solvent or white spirit. This is especially true if you plan to use a sprayer in operation.
Нанесение следует осуществлять в сухую погоду, when the temperature is kept in the range from -10 to +30 ° C. It is important to provide intermediate layer-by-layer drying, if the application will be carried out in two layers. In the future, enamels and paints can be applied to the surface on oil, pentaphthalic and chlorovinyl bases.
Paint enamel PF 115 is resistant tolow temperatures and precipitation, after drying forms a waterproof film. The mixture is made on the basis of pentaphthalic. It is used for painting surfaces outside and indoors. Mixture can paint exterior, interior, piping, radiators, frames and other surfaces.
The main color is white, but on saleYou can find yellow, blue, green, gray, cream and beige shades. The paint is resistant not only to weathering, but also to ultraviolet, as well as temperature differences ranging from -50 to +60 ° C. The paint forms a waterproof coating and perfectly copes with the effects of cleaning solutions. With the help of paint-enamel, you can create a smooth decorative uniform coating that has a 50 percent haze and does not form smudges.
Today, a fairly common typePaint coatings are enamel. They may have different properties and purpose. Solutions are intended for application to metal and wood, as well as other materials. As a distinctive feature of enamel paints, it is possible to distinguish high hiding power, moisture resistance, coloring ability, atmospheric stability and excellent tolerance of sunlight.
