Paints and varnishes (paint and varnish materials) are a multicomponent system that is applied in liquid or powder form to a previously prepared surface and, after drying (hardening), forms a durable film that is well adhered to the base. The resulting film is called a paint coating. Paintwork materials are used to protect metal and other types of products from the influence of external harmful factors (moisture, gases, air, etc.), giving the surface decorative properties.
How to test fabric for color fastness
Bright fabric can fade due to poor-quality coloring if the technology for coloring the material is not followed. The quality of the material from which the product is made is also important. There are situations when a wardrobe item is of high quality, but still loses its color saturation after washing. The question immediately arises: what to do if the fabric fades.
Fixing the dye on the material
It is advisable to check any colored clothing for the degree of shedding. After checking, wash the product by hand or set the washing machine to a delicate cycle at a temperature of +30 degrees.
Brightness test for strength
- The easiest option is to apply water to a small area of clothing. You need to press the paper to the wetted area and, together with it, run the iron over the product. If there is a trace of paint left on the sheet, then this object will lose its bright shade.
- Near the seam of the garment, you need to carefully cut off a piece of material. Place in a container with a small amount of alcohol for a few minutes. After this, press the piece onto the product. If the clothing is brighter in comparison to a small section, then obviously it can fade quickly.
- Place a piece of cloth in warm water with diluted powder for 10 minutes. Wrap the item in a white cloth and wring both fabrics together. If pigment is imprinted on white material, then in the future you will have to care for the item more delicately.

Plasticizers
Plasticizing additives are used in paints and varnishes to give them elastic properties during operational processes. They promote uniform mixing of all the constituent elements of the paint and varnish material, lower the temperature during technological processing of the product, and increase the frost resistance of polymer compounds. Certain types of plasticizing additives improve the fire, light and temperature resistance of polymer particles.
Plasticizers must meet several requirements in order to have sufficient compatibility with polymer compounds.
- Low level of evaporation.
- They should not have a smell.
- Be chemically neutral.
- Be able to withstand liquid polymer extracts.
The percentage of plasticizing additives in a paint and varnish material can fluctuate over a wide percentage range in relation to other components. Their quantity regulates the volume of water in the product, gives the paint the necessary parameters of viscosity and density, and increases the adhesion of the material to the surface being treated. At the same time, an excess of plasticizing additives can lead to undesirable thickening of paint and varnish, which will negatively affect their quality.
How to properly wash faded items in a washing machine
If the fabric is fading and you don’t know what to do, you can be smart and try a few tricks before washing:
- It is advisable to sort by color - wash black with black, and red with the same fabrics by shade;
- you can buy a powder that contains a fixative for paint and shade for fabric;
- It is better not to use stain removers and conditioners for such things;
- the water is suitable cool or warm about +40 degrees.

Raw materials for paint and varnish products
To trace the entire production process, during which multi-colored paints, shiny varnishes, and excellent enamels are born, you will need quite a bit of scientific work at the dissertation level.
After all, it’s really interesting to look into the smallest details of this fascinating work, to get inside a can of paint to find out how it is made and what it consists of. Let's try to do this without going into deep details, but carefully delving into everything important and interesting.
In order to produce high-quality paints and varnishes, raw materials are needed. If previously natural and plant-based raw materials were used, now manufacturers have switched to a synthetic base, which has improved the quality of the final product, as well as significantly expanded its range. Let's figure out what paint and varnish materials are made of.
Never use bleach
As mentioned above, in order to maintain brightness for a long time, you should not wash the rag product in bleaching powders and gels. In addition to the fact that the material itself cannot retain paint, bleach helps to further lighten the item. Bleaching particles can break down chemical bonds. This destroys not only the color, but the product itself.
Bleach is not suitable for colored fabrics
How to wash without dyeing things
If any product loses its color with each wash, much less its color and leaves marks on the body, then you should try washing it a little differently. If, for example, jeans are not heavily dyed, then you can try to remove excess coloring pigment from them. One simple option:
- If you have jeans that often fade, you should soak them in warm water.
- You must not skip the step of rinsing the product under running cool water.
- It is recommended to soak the jeans again for 40-50 minutes.
- When the amount of dye decreases, you need to rinse the product under the tap.
- Soak again until the excess pigment comes off.
- Wash in a washing machine with color-preserving powder.

Paint and varnish materials and products
Paints and varnishes are a viscous-liquid mixture that is applied to the surface plane of any item or object. After some time, it dries, forming a protective layer that has strong adhesion to the surface.
There are several types of paints and varnishes.
- Primer and putty mixtures that prepare the surface for painting. Their application to the surface being processed gives the latter uniformity and evenness.
- Paint used in the form of a paste or in a viscous-liquid state. It gives the coating the required color.
- Pigmented particles and binding components are the main components of paint compositions.
- Varnishes that form a filmy shiny layer.
- Solvents and thinners.
- Plasticizing, hardening paint polymers and many other special additives.
Paint and varnish products are used to improve the appearance of architectural facades; with its help, you can change the style of any room, creating a unique interior in it. Often, paints and varnishes are used to extend the life of structures and objects from negative environmental influences.
The outer part of building facades is often subject to the destructive effects of weather factors (precipitation, wind, temperature changes, unfavorable environmental conditions). Using paints and varnishes with water-repellent and elastic effects, you can increase the service life of objects without major expensive repairs for several more years.
Paint and varnish products intended for highly professional use are widely used. This paint has increased chemical resistance. It is used to protect metal and reinforced concrete structures from corrosive processes. There are paints with a similar protective effect intended for wooden objects.
There are heat-resistant paints and varnishes that are used to coat industrial machines and other equipment.
Sanitary equipment and pipeline units also need to be covered with similar materials for more productive work.
Enterprises producing paints and varnishes produce them ready for use; you just need to add a solvent or dilute them to obtain the required consistency. Complex design connections with many parts that must leave the production site assembled are painted directly in the assembly shops. To accomplish this, a special painting conveyor has been organized at production sites.
