Our hardware and technology park is equipped with all necessary and the most diverse range of equipment - from high-tonnage installations bringing into compliance and chemical reactors, to dispersing plants, filtering and high-precision metering stations.

Our PWM serve as protective and decorative coatings on metal products that are operated outside and inside the premises, including consumer goods. The products of Uralprotect provide a combination of properties necessary for forming and profiling steel rolled products, such as elasticity and strength. In addition, our coatings show a high resistance to weathering and corrosion, ultraviolet radiation (corresponding to classes RUV3 / RUV4).

Manufacture of the paint and varnish Uralproteсt products is carried out on the following stages:

  1. Production of colorless and colored semi-product from a raw material resource
  2. Mixture of semi-products. Enamel compilation
  3. Bringing into compliance
  4. Filtration and packing of finished goods.
Stage 1

STAGE 1. Semi-products manufacturing

Enamels for Coil Coating are produced from a large amount of o raw components that require pre-treatment. For this the first stage of paint and varnish manufacturing is necessary - the production of semi-finished products from a raw material resource. Semi -products are divided into two main groups: colorless and colored.


  • Colored semi-products include: pigment pastes of different colors and shades.
  • Colorless semi-products include: mixtures of resins and solvents, polymerization catalysts and additives for various purposes.


Colored semi-products (pigmentary pastes) are made by dispersing loose pigments in a mixture of resins and solvents.

The main dispersing equipment is a dissolver and a bead mill. A dissolier is intended for preliminary preparation of a semiproduct and coarse grinding of a future pigment paste. Bead mill is designed for fine grinding of the paste to the desired degree of grinding, according to the requirements of the technology. When carrying out dispersal work, it is important to remove heat from the working area.

Colourless semi-products (pitches, solvents, additives, catalysts) are manufactured by successive mixing of the necessary components in dissolvers.

At this stage, we get the so-called "semi-finished product".

Stage 2

STAGE 2. Mixture of semi-products. Compilation of enamel.

At this stage, all the necessary semi-products are mixed with a given sequence, quantity, temperature and time in the equipment of different capacity with constant stirring and heat removal. As a rule, the capacitive equipment is equipped with an anchor-impeller mixer.

At this stage, we get the so-called "product".

STAGE 2. Mixture of semi-products. Compilation of enamel.
Stage 3

STAGE 3. Bringing into compliance

Bringing into compliance is the method of bringing the "product" to the state of "finished product" with the required level of quality. I.e. if "the product" has discrepancies in color, this is corrected by adding pigment tinted pastes, if in viscosity and mass fraction of non-volatile substances - by adding solvents or resins, and if in gloss, then by addition of matting additives. Addition is strictly performed with prolonged mixing in order to distribute additives evenly throughout the volume of the "product". When the specified values ​​are reached, the enamel is stabilized by stirring for 1 hour. The enamel brought into compliance is sent to the stage of filtration and packaging.

At this stage, we get the so-called "finished product".

Stage 4

STAGE 4. Filtration and packing of enamel

Filtering and packing happens at the same time with the help of a pump-filter group (PFG) and floor scales-platforms. Pump-filter group is equipped with a micron filter with different cell sizes from 10 or 25 microns. PFG forcibly extrudes finished products through itself to ensure that it is clean from extraneous inclusions. Packing takes place in the container on the scales. At the end of the filling, an arbitration sample is taken from the enamel batch for testing in the quality control laboratory.

A metal barrel with the opening top is used as a container. A container is pasted over with labels, set on pallets, reinforced with a braid band around the perimeter of the pallet and sent to the pallet packer. The pallet packer- is a device, which wraps a pallet into a polymer protective film. Then the finished and packaged products are exported to the storage of finished products and then shipped to the consumer.

At this stage, we get the so-called "product for sending to the consumer". The process of manufacturing the paintwork is completed.
