Technical characteristics and scope of enamel EP-572, how to apply it
The use of EP-572 enamel is suitable for various types of coatings. This material is a two-component epoxy paint that includes a hardener. It is characterized by high mechanical strength and reliable adhesion to marking coatings, resistance to various climatic factors and fungi. The dye contains pigments and polyethylene polyamine.
Peculiarities of the composition
EP-572 enamel includes benzyl alcohol and dyes. The first component makes the material more durable. The suspension also contains polyethylene polyamine, which acts as a hardener.
Apps
The dye is used to mark various products. The composition is recommended for processing various types of metal coatings. They can be copper, aluminum, titanium, steel, silver. The material is also firmly attached to other substances.
The emulsion is suitable for processing steel coatings, which were previously coated with certain types of enamels. These include ML-165, ML-12, EP-773, PF-115.
Features
The composition is distinguished by a high degree of resistance to mechanical factors. In addition, it has excellent grip parameters. This means that the substance adheres firmly to other coatings.
Enamel can be used in different types of climate. It prevents the growth of fungi.Items that have been coated with this type of enamel can be used in different temperature conditions - from -60 to +250 degrees.
The substance is characterized by resistance to the negative influence of various factors. These include water, alcohol, gasoline. In addition, the composition is resistant to automotive oils.
Most often, enamel is produced in white, black and red colors. There is also a yellow tint. However, some manufacturers also offer other colors. On sale there are glazes packaged in containers with a volume of 1, 3, 18 liters.
It is allowed to store enamel in an airtight container for 1 year from the date of issue. This should be done in a dark, cool place. The technical characteristics of the coating are regulated by TU 6-10-1539-76. The key parameters are shown in the table:
| Indicator | Sense |
| Color | red, white, black, yellow, green |
| Entirety | For 100 parts by weight of undiluted enamel, 5 parts by weight of THETA or PEPA are required. After combining the ingredients, mix everything well and wait for half an hour. |
| Period of application after the composition of substances | 06 hours |
| Mixing with solvents | Cyclohexanone, acetone, ethyl cellosolve, toluene, acetone |
| Convenient drying At 65 degrees At 140 degrees | Up to degree 5 2 hours 30 minutes |
Color spectrum
There are different shades of this type of enamel on sale. In addition, it is most often produced in white and black colors. There are also red and yellow tones. Some manufacturers offer other product shades.
Application rules
For the successful application of the composition, it is important to properly prepare the surface. This will provide an even coating.To do this, it is recommended to clean it from dust, dirt and corrosion products. High-quality degreasing of the coating is not negligible.
Before use, it is recommended to add PEPA hardener to the enamel composition. The volume of the substance should not exceed 5% of the total amount of dye. If the solution has the wrong viscosity, it is worth additionally using various solvents. Effective agents include acetone, toluene. Cyclohexanone or ethyl cellosolve will also work.
It is allowed to apply the coating with pens, brushes, stamps. A setting pen is also suitable for this. The viscosity parameters measured by the VZ-4 viscometer depend on the method of application and can be 13-15, 18-20, 15-30, 13-15 seconds.
It is worth applying the composition in 1 layer. The drying time when using the heat drying method is half an hour to 2 hours. The specific parameters depend on the temperature indicators. At 140 degrees, the composition dries for half an hour, at 65 - 2 hours.
The duration of hardening of the substance is 1 day. This period of time is necessary at room temperature. A coating that has hardened in 2 hours at 60 degrees with a 2-3 day dwell time can be rinsed off with lukewarm water. Its temperature can be 40-50 degrees. Also, the coating can be exposed to ethyl alcohol or gasoline. Also, a mixture of them is allowed.
It is important to take into account that the composition of EP-572 is considered a rather toxic material. In addition, it has fire hazard properties. Therefore, when working, it is recommended to observe safety rules. In this case, it is worth doing the following:
- protect hands with rubber gloves;
- wear a respirator so that the vapors of the substance do not enter the respiratory system;
- use special clothes to protect against the negative effects of the composition;
- apply the enamel away from sources of ignition and an open window;
- ventilate the room well or use ventilation.
Storage conditions
The material can be stored for 1 year. Moreover, it should be done in a sealed package. It is recommended to keep the enamel in a dark and cool place. The composition should not be exposed to direct sunlight. The substance should be kept out of the reach of children.
EP-572 enamel is very resistant to mechanical factors. For a successful coating, it is important to strictly follow the instructions. Compliance with safety rules is of great importance.
