Enamel is a suspension of pigments with fillers in lacquers, which form a hard opaque film with different textures after the drying stage is completed. It is for these qualities that modern consumers choose these formulations more often than others. In addition, they are capable of performing several functions at once, for example, decorating and converting rust. As a result, the surface can turn out to be moire, matte or glossy. In terms of physical and mechanical properties of films and protective characteristics of enamels, they are superior to water-dispersion and oil paints. Among the main characteristics, elasticity and hardness can be distinguished.
General Description
As a rule, enamel is a composition that contains a large amount of film former and a small amount of filler. Synthetic varnish acts as the first ingredient, while the filler has an increased decorative effect. Enamels are intended for the formation of the upper layers of the coating, which are subject to different and high requirements for durability.to the influence of negative factors and decorativeness. These mixtures are intended for painting metal and wooden surfaces, as well as for giving them weather resistance and wear resistance. Compounds may have different colors.
Main types of enamels
Enamel is a composition that can be aerosol, 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 for painting various wooden and metal surfaces, namely:
- boats;
- bicycles;
- doors;
- furniture;
- windows.
Alkyd enamels can be used both outside and inside. Heat-resistant enamel is a mixture designed for painting radiators that are used at temperatures up to 100 ° C.
Classification of enamels
Having visited the store, you can find enamels, which are indicated by different abbreviations. For example, enamel, denoted by the letters PF, is a pentaphthalic mixture, which is made on the varnish of the same name. There are GF enamels on sale, which are called glyptal. Silicone-organic compositions are characterized by high heat resistance, while NC-enamels are made on the basis of nitrocellulose and are characterized bystatic resistance of surfaces, liquids and industrial oils.
On the basis of chlorinated, polyvinylchloride and alkyd resins, XV-enamels are produced, which are characterized by excellent weather and chemical resistance and resistance to atmospheric phenomena. On the basis of acrylic, AK enamels are made, which have high light resistance and the ability to maintain whiteness under ultraviolet irradiation. Based on alkyd and acrylic, AC enamels are produced, which are distinguished by excellent protective properties and the ability to maintain their qualities in tropical and temperate climates.
On the basis of alkyd and epoxy resins, EP enamels are produced, which belong to category B2. This indicates that the mixture can be used in all zones except the Far North. Based on phenol and oil varnish, FL enamels are made, which have higher quality characteristics in terms of hardness, drying speed, wear resistance and gloss.
Characteristics of Belinka Email Radiator alkyd enamel
The characteristic of enamels, which you can find in the instructions on the packaging, allows you to understand what certain mixtures are intended for, as well as by what technology they should be used. For example, the enamel mentioned in the sub title is a coating mixture used to coat old and new radiators, as well as indoor heating pipes. After drying, the surface acquires a glossy sheen, and the layer is heat resistant.
Based onmodified quality alkyd resin, fillers, temperature stable pigments, organic solvents and additives. It is necessary to apply the solution with a brush with natural bristles in one or two layers. Tools can be cleaned after completion of work with a rag soaked in mineral spirits, thinner or gasoline.
Additional recommendations
Such enamels, reviews of which are only the most positive, dry within 24 hours, this also applies to interlayer drying. You should not start work if the thermometer has dropped below +10 ° C. If you have to work with a radiator, the surface of which has been cleaned from other coatings to metal, then you need to start work by applying a primer.
Feedback on application features
Before using the enamel described above, it is necessary to prepare the painted surface, for this it must be freed from dust, dirt, as well as rust and moisture. To remove rust, you must use a wire brush, chemicals or sandpaper. Nitrosolvents will allow you to get rid of greasy contaminants.
According to buyers, the enamel must be well mixed before application. Application can be done by spraying or brushing. The application of the second layer should be carried out a day after the first. Such enamel, the technical characteristics of which were mentioned above, can be cleaned on the surface of the radiator. According to users, this can be done no earlier thanone month after dyeing.
Characteristics of Mister Hammer rust enamel
Quite often in everyday life there is a need to apply enamel on surfaces that have been affected by rust. To carry out such work, you can use the enamel mentioned in the sub title, which is sold in cans of 2.5 kg. For such a volume of composition, the consumer will have to pay 895 rubles. The color of the solution is silver. With this mixture, you can convert rust, carry out anti-corrosion priming and paint the surface to achieve a decorative effect.
Enamel can be used for painting in atmospheric conditions, as well as indoors. After drying, the layer acquires high weather resistance, anti-corrosion resistance and increased moisture resistance. This enamel over rust forms a kind of coating in the form of a pattern that resembles hand chasing. After you can get a hammer textured pattern, with which you can mask minor defects.
Composition consumption
It is noteworthy that a single-layer coating will dry within 4 hours, but the base will dry to the touch in just an hour. The degree of gloss will depend on the tool and application method. In order to achieve a hammer effect, the application should be carried out in two or three layers. At the same time, you should be prepared that for an area of 5 m22 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 homeconditions, but this is not all that you need to know before applying. For example, an alkyd component is used as the base, but the mixture cannot be tinted.
Characteristics of the primer-enamel 3 in 1 brand "Lacra"
The Lakra company offers for sale a 3 in 1 primer-enamel made on an alkyd basis. The composition is able to convert rust, decorate the surface and have an anti-corrosion effect on it. After drying, you will get a glossy finish that is resistant to atmospheric and mechanical influences. The mixture is universal, because it can be used not only for indoor, but also for outdoor work.
Enamel is intended for painting rusty, clean and partially coded metal surfaces, on the basis of which rust up to 0.1 mm thick is contained. This 3 in 1 rust enamel should be applied to a prepared surface, which should be cleaned of dirt, dust, and loose rust. Peeling old coatings can be removed, if necessary, the surface must be degreased.
If oil or alkyd paints were previously applied to the surface, then they must be cleaned to a matte state, and then checked for strength and compatibility. To do this, experts recommend a trial staining. If the old coating peels off, then it should be removed. Before use, the primer-enamel must be mixed well, if necessary, or before painting, the composition can be diluted to a working viscosity with a solvent or white spirit. This is especially true if you are planninguse a pneumatic spray gun.
Application should be carried out in dry weather, when the temperature is between -10 and +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 on oil, pentaphthalic and vinyl chloride bases can be applied to the surface.
Characteristics of enamel paint PF 115
Paint enamel PF 115 is resistant to low temperatures and precipitation, after drying forms a waterproof film. A mixture is made on a pentaphthalic basis. It is applied to coloring of surfaces outside and in rooms. The mixture can be used to paint exteriors, interiors, pipelines, radiators, frames and other surfaces.
The main color is white, but on sale you can find yellow, blue, green, gray, cream and beige shades.
