For the successful and long-term operation of metal products, the protection of these elements from external influences is required. Enamel EP-773 is an optimal coating option that will protect against moisture, corrosion and scratches. To understand how to properly apply the coating in question and the features of its operation, it is necessary to study in more detail the composition and rules of handling this tool.
Purpose and properties
The chemical basis of the enamel EP-773 and the technological features of its preparation are determined by the provisions of GOST-23143-83. Given the official documentation, the composition in question is created on the basis of epoxy resin with admixtures of various pigment fillers and additional ingredients.
The product refers to two-component solutions in which the coloring mass is mixed with the hardener immediately before application to the processed object. The advantages are significant protective properties against external influences of a diverse nature.
Using this substance, you can protect the surface from the following problems:
- increased exposure to moisture;
- oil substances;
- salts of mineral origin;
- combustible components, including gasoline and similar compounds.
Anticorrosive enamel EP-773 (GOST-23143-83) is appropriate for the processing of ferrous and non-ferrous metals, ensuring their long-term use. In addition, it is suitable for painting concrete areas after preliminary priming. In domestic conditions, this composition is indispensable in the decoration of plumbing assemblies, pipelines, various designs and equipment. Additional advantages: profitability and practicality.
Features
Enamel EP-773 perfectly protects metal surfaces from thermal effects, alkaline solutions, atmospheric precipitation and rapid wear due to mechanical stress. The paintwork of this configuration creates a semi-matt or matte finish. Other characteristics of enamel:
- Working viscosity - 25-60, which allows you to apply the composition manually or by spraying.
- The density index is achieved by a pair of layers whose thickness is not more than 25 microns.
- The material has excellent adhesion to metal surfaces, can be applied to the primer without it.
- Drying at the finish stage takes 24 hours, with artificial heat treatment this figure is reduced to two hours.
- The resulting layer has high elasticity.
- For each applied layer, the consumption is about 75 grams of paint per square meter of area.
Color palette
EP-773 epoxy enamel is available in two main colors: green and cream. Under the order, you can pick up any of the sought-after colors. One nuance should be taken into account here: under the influence of potassium alkali, tones of creamy directions lose their stability. After the painting procedure, the color, if it is selected correctly, does not differ from the standard color, and a smooth film coating is formed without impurities.
How to prepare a solution?
In the manufacture of the composition in the room, the tank at room temperature can withstand about 24 hours. Before directly preparing the main mixture, make sure that the semi-finished product has turned into a homogeneous mass.
Further stages of preparation of enamel EP-7736:
- The hardener is introduced into the composition taking into account the proportions indicated in the paint application manual.
- Mixing the components of the composition is recommended for 10 minutes, which will allow you to get a homogeneous mass with good performance and appropriate appearance.
- The viscosity when using a spray gun should be no more than 16 s, with a 4 mm nozzle, otherwise a solvent of the recommended brand is added. It should be remembered that excessively liquid composition can cause leaks on inclined and vertical surfaces.
The final mixing is carried out using a screw nozzle for a mixer or a construction drill.
Recommendations
With the heterogeneity of the resulting solution based on enamel EP-773, the painted part in some places may discolor and dry out. Solving this problem is somewhat more difficult than taking measures to prevent it. Due to these nuances, the hardener is distributed unevenly, which leads to premature thickening of the composition. In connection with such features, an open trough is used for processing.
For reference: staining is not carried out on wet surfaces, the base should be covered with a primer in 1-2 layers, before applying the composition, the object is thoroughly dried and cleaned with a clean rag.
Preparatory work
At this stage, not only the EP-773 enamel consumption is calculated, but also the ability of the composition to process a given area. When preparing the surface, the following procedures are performed:
- Cleaned of scale, extrusions, dirt and debris.
- Grind and remove rust.
- Degrease the surface.
Before applying the enamel EP-773, a preliminary primer is produced, oriented on surface treatment with epoxy materials. To obtain the desired result, standard EP-type solutions are quite enough. Concrete surfaces are recommended to be additionally treated with Sibton type agent.
Security
The technical characteristics of the EP-773 enamel indicate that the composition of the mixture is flammable and requires compliance with certain rules during storage and transportation. Products should be painted on open ventilated areas or in hangars with an appropriate level of ventilation.
The mixture used in the form of enamel EP-773 (GOST-23143-83) should not be stored near fire sources. Fire safety requirements imply preventing the storage of the substance in question close to aggressive factors that provoke wear of the container or damage to the paint itself.
If the composition gets on your face, skin or mucous membranes, the affected areas must be washed with running water, and then washed with soap and water.
If the treated surface will come in contact with an aggressive environment, it makes sense to acquire high-quality compositions, without focusing on cheapness. The fact is that low-quality paints quickly go off and do not provide adequate protection. Enamel EP-773, the technical characteristics of which are discussed above, is a semi-finished product that reliably protects the treated surfaces from various kinds of aggressive influences.
In conclusion
There are many paints and varnishes on the market. Enamel EP-773, the consumption of which is one of the lowest from the calculation of one coating layer per square meter, protects the surface from corrosion and scratches. At the same time, the range of products is presented in several colors, which makes it possible to choose a shade for a specific design design.
