Short description

Lacu bakelite LBS 1 is a formaldehyde resin mixture that has been dissolved with ethyl alcohol.

This composition is widely used as a glue, connector, and impregnating substance for a variety of materials. These characteristics are fundamental to the means. Furthermore, bakelite is known to form a barrier against hot liquid mixtures, poorly separated acids, gasoline staining containers, and the formation of plastic binding parts in layers.

Production of varnish

Phenol, formalin, ethyl alcohol, and ammonia are added by the manufacturer to create LBS varnish, which starts a chemical reaction. In Russia, production is governed by GOST 901-78 guidelines.

Technical attributes are directly correlated with the features found in the substances’ composition.

Bakelite in Russia

The novel material was created in 1914 in Russia by chemists AND. Lisev, g. WITH. Petrov, and K. AND. Tarasov using formaldehyde resin and phenol. They called the product carbolite.

These days, plastic based on phenol-formaldehyde resins is produced by many plants. Not only is leaf material produced, but liquid bakelitis and bakelite resin, such as SBS 1, are also produced.

The scope of application

Bakelite varnish is utilized in a variety of construction projects and in the production of various materials. Thus, the following can be identified as distinct areas of application:

  • Coating of various types of bases, also to connect them and impregnate them with a coloring substance;
  • To protect devices with heat exchanger property from the harmful effects of hot liquid products;
  • Create a protective layer from the influence of acidic and salt elements of medium degree of influence;
  • Varnishing of gasoline and oil TAR;
  • Obtaining a connecting layer in the production of certain types of plastic objects;
  • Release of metallic and other abrasive types;
  • Creation of chemical fibers;
  • To protect the pipeline and air cleaning parts of the filters from corrosion;
  • To increase the durability of wood and concrete products;
  • In mechanical engineering.


Varnish is a translucent solution with a burgundy or red hue on the outside. The solution is a homogeneous fluid free of impurities and foreign substances. Bakelite resin makes up between fifty and sixty percent of this kind of coloring product. The range of viscosity levels is 100 to 900 MPa.

The varnish has a maximum of 10% water content and up to 9% phenol-free ingredients. Gelatinization takes 60 to 120 seconds at most.

Important rules

When applying the varnish material to large containers, it’s crucial to follow these guidelines when working:

  • The base before application should be well cleaned of all pollution, including rust, oil spots, etc.P. It is necessary to achieve absolute purity and wait for drying;
  • Before use, the composition is well stirred;
  • After processing on the base, the film remains, it needs to be thermally processed, the temperature rises in stages to 160 degrees. A similar approach allows you to create a mesh polymer, if the temperature is increased to 150 degrees, then the process takes no more than 2 minutes;
  • If varnishes are carried out by a brush, then the consumption will be equal to 120 g/m2;
  • The storage of the composition should take place in a black place at temperature indicators no higher than 20 degrees.

Synthetic resin known for its extraordinary heat resistance and durability, bakelite varnish is a multipurpose coating used in many industrial applications. This article examines its special application features and technical attributes, emphasizing its superior chemical resistance, electrical insulation capabilities, and superior adhesive qualities. Understanding the benefits and application procedure of bakelite varnish can help in choosing the appropriate product for particular needs, ensuring long-lasting and effective results, whether for electrical components, protective coatings, or high-heat environments.

Processing with bakelite resin

The term "substance" describes efficient anti-corrosion compositions that are applied to create a barrier against various chemical influences and rust. It’s critical to understand the characteristics of each processing step in order to complete tasks accurately.

Use of bakelite paintwork

Since the composition is frequently used to safeguard various chemical devices, the surface coating procedure will be taken into consideration for this reason. Both surface preparation and direct varnish application are covered in the instruction.

Preparatory stage

It is crucial to remove any and all contaminants from the surface. To create a pure base that turns gray with a matte effect, use a shot-best or sandblasting tool.

When up to 40% of the filling material is present and the varnish has been well-mixed, the product can also function as a primer layer. This additional protective processing from rusty formations is done by passing the application through a brush and slightly pressing on the tool to soak the material well. This step must be completed no later than three hours after processing.

Applying varnish

Under normal circumstances, the layer should dry for four hours before polymerization takes place. After priming the surface, a second layer of a bakelite agent containing 25% filler is applied, and the layer is then polymerized. Processing is brought to a three- or four-layer state, but no filler is added, and the layer shouldn’t be any thicker than 0.5 mm.

A brush is used to paint the entire surface; if the item is large, a spray gun can be used; however, it is crucial to ensure that there are no influx or unprocessed areas.

If you glue the cotton fabric to the surface after priming, you can obtain dependable mechanical protection. The fabric must be starch-free, cleaned, dried, and cut to the correct size. Put the tissue in a 25% bakelite varnish solution, let it sit for five to six minutes, and then squeeze. In order to eliminate the diluent, the material should be dried in the open while wearing rubber gloves on the hands.

The prepared material is applied in a cast state and adhered to the surface. It is not recommended to apply pressure to the fabric with a brush after the varnish has been applied to the surface.

Numerous benefits come with bakelite varnish, which effectively shields various surfaces from harmful elements. Given the characteristics of the task, varnishing correctly is crucial for a high-quality outcome.

Because of its exceptional resistance to deterioration and wear, bakelite varnish is a preferred option for many industrial uses. Because of its resistance to chemicals and high temperatures, it works well in harsh conditions where other varnishes might not hold up.

For best results, bakelite varnish application requires close attention to detail. To ensure that the varnish adheres properly, surfaces must be thoroughly cleaned and prepared. To ensure a smooth finish and avoid imperfections, apply thin, even coats of varnish.

Excellent electrical insulating qualities are one of bakelite varnish’s primary technical features. Because of this, it is especially helpful in the electrical and electronics sectors, where it helps shield components from harm and improves their functionality. Furthermore, after curing, its hardness and toughness offer enduring protection for a variety of materials.

In conclusion, bakelite varnish provides a hard-to-match combination of durability, heat resistance, and protective properties. Bakelite varnish is a dependable option for any project requiring a long-lasting finish, whether you’re working on machinery, electrical components, or other projects. Applying it correctly is essential to maximizing its benefits and guaranteeing a durable, high-quality finish.
