Main purpose
Enamel ML-12 is used for painting metal surfaces that will be used inside the house and beyond. Substrates and articles may be exposed to precipitation. However, they should first be primed, and additionally can be coated with putty.
Specifications
The enamel ML-12 forms a film, which should be homogeneous, It should not have excess inclusions, smallpox and wrinkles. However, shagreen is acceptable. The color of the film should be within the tolerance set by the samples. The rest correspond to the sample number.
Professionals quite often are interested in conditional viscosity, it can vary from 70 to 120 s. As for the gloss of the film, it is equal to 58%. Whereas for protective shades, this value varies from 35 to 45%.
The mass fraction of non-volatile substances varies from 44 to 60%. The final value depends on the color, as well as the degree of grinding. This parameter for enamel ML-12 may be equal to the limit of 10 to 15 microns. The elasticity of the film during bending is 3 mm. The opacity of the dried enamel layer, depending on the color, can vary from 35 to 100 g / m². But if you get paint in the color of white night, then for it the spreading rate will be 60 g / m². The film strength when tested using the U-1 device is 45 cm.
Additional specifications
Quite often, professionals pay attention to the hardness of the film on a pendulum device. If type M-3 is used, then the hardness will be 0.5 so. Whereas for a pendulum A of type TML, the hardness is 0.3. The adhesion of the coating is 1 point, but not more. You may also be interested in the conditional lightfastness of the mixture after drying, it is 4 hours or less.
Consumption and application features
Enamel ML-12, the technical characteristics of which were mentioned above, can be used for application on agricultural machinery and truck bodies. Dilute the mixture with the following solvents:
- solvent;
- xylene;
- solvents of grades 651 and RKB-1.
When preparing in the process of priming, the compositions GF-0119, GF-021 are used. Application is carried out on a dried primer in 2 layers. Intermediate drying should be approximately 7 minutes, which is true at an ambient temperature of 20 ° C. You can use a spray gun for application. Usually 2 layers are applied.
Consumers are often interested in the consumption of enamel ML-12. For each square meter with a single-layer coating, you will spend about 80 g. Depending on the type of surface, this value can be increased to 100 g per square meter. The surface to be painted must be cleaned from rust, dirt and dust during the preparation process. The base is degreased. If you have to work with the old coating, then the surface is additionally polished. After the primer is applied. You can use one of the above formulations for this.
Application Features
Before use, the enamel must be mixed well and diluted with a solvent to 25% by weight of the base material. Application is carried out in two layers. If you have to work with the old coating, then the number of layers must be increased to 2. The second layer must be kept for about 30 minutes at a surface temperature of 130 ° C.
Enamel consumption varies depending on the complexity of the product being painted and the thickness of the formed layer. In order for the ML-12 melamine enamel to remain for a long time in a closed container, it must be stored, protected from sunlight and moisture, kept away from heat sources.
What else you need to know about enamel
The enamel described is suitable for application on different surfaces and products, it can be:
- motorcycle;
- auto;
- cycle equipment.
Covered surfaces can be used under different conditions. After drying, a uniform film is formed on the base without delamination and impurities. Implemented enamel ML-12, the characteristics of which were mentioned above, in an industrial container, its volume starts from 18 kg.
Enamel Manufacturers
In the market, the enamel described in the article is offered by different manufacturers. Among others, it is worth highlighting the Regionsnab. This company is located in Moscow and supplies enamel in 50 kg containers. You can buy a kilogram of products for 120 rubles. She offers to find lower prices, then the goods are supplied at a reduced cost.
Another manufacturer - Khimprom-m offers to buy enamel at 135 rubles. per kilogram. This company positions its products as car paint. Experts recommend using it for decorative and protective painting of metal surfaces. With the help of this composition, according to company representatives, it is possible to correct minor damage to coatings of vehicles, elements of industrial and other equipment, as well as bicycles.
Another manufacturer of enamel ML-12 is Chelyabinsk Paint and Varnish Plant. He supplies enamel, advising her to dry it hot. The manufacturer recommends regulating the working viscosity with xylene. If necessary, the enamel can be filtered through a mesh. In the cold season, the material is heated to a positive temperature before use.
You can also buy enamel of the described brand in the Yaroslavl Paint and Varnish Company. The supplier provides a warranty period for the storage of material for 12 to 24 months, which will depend on the volume of the container. The manufacturer emphasizes that the conditional viscosity during prolonged storage can be increased. After the warranty period has ended, the enamel can be checked, if it meets the requirements of the technical conditions, then it can be used for its intended purpose further.
Conclusion
ML-12 has many positive features. Among them, protective, strength and decorative properties should be highlighted. The material has proven itself on the conveyors of Russian car factories. It has a low wholesale cost and decent quality.
Application can be carried out by spraying, which reduces the time of work. If surface treatment is carried out in an electric field, then RE-1V and RE-2V compounds can act as diluents. It is also noteworthy that the enamel is offered for sale in a variety of colors. In addition, you can be sure of its quality for the reason that the paint is manufactured according to state standards, which means that it meets all the norms and requirements.
