Polyester primer for cars: rating of the best. How to use polyester primer
Content
For minor damage, aerosol cans are indispensable. Polyester primer for cars is applied in a few minutes. After complete drying, the surface is sanded, so that the defect disappears.
Vehicle owners know that the result is not so much affected by the quality of the paintwork, but by correctly performed preparatory work. Today, for such purposes, polyester primer for cars is more often used. This type of coating began to be used not so long ago, in comparison with polyurethane and acrylic options.
What is polyester primer for cars
The material began to be studied in the 1930s, and since 1960 the resulting compositions have been used in all industries. Based on saturated polyester resins. The primer is used in the automotive industry in order to obtain a transparent glossy finish.
The substance outperforms other materials with good adhesion, surface hardness, chemical resistance, abrasion and scratch resistance.
Polyester primer
Polyester primer for cars consists of three components:
- the basis;
- accelerator;
- catalyst.
Before use, the elements are mixed, observing the proportions indicated by the manufacturer. The substance has a specific smell due to the presence of styrene - this is a reagent that is part of saturated polyesters.
The mixtures contain paraffin, which does not allow free radicals of the monomer to enter into a chemical reaction with oxygen during decomposition, and the connection between the surface of the body and the primer is faster. After drying, the layer is removed by grinding.
Material advantages
The main advantage of a polyester primer for cars in spray cans is that it dries quickly on the surface of the body. If the room temperature is 20ºWith or above, the process takes 90 to 120 minutes. When using an industrial hair dryer, the drying speed increases several times. The only condition is that the permissible temperature must not be exceeded.
In addition to the spray can, a gun or spray gun is used to apply the primer. The composition has high physico-chemical properties. One layer is enough to obtain the required dry residue, which saves material.
Putty with carbon fiber
Unlike acrylic primers, polyester primers do not boil when smudges form and the resulting surface is easy to grind. Withstand temperatures from -40º to +60ºС.
Thanks to these properties, the material occupies a leading position in the market.

How to properly use a polyester primer for cars in spray cans
After a competent choice of composition, compliance with all norms in work is the key to a successful result.
The process consists of several stages:
- Before starting, the surface of the machine is cleaned.
- To improve the adhesive characteristics, the area is degreased.
- The selection of the composition depends on the coverage.
- Polyester primer for cars in spray cans is applied at an angle of 90º from a distance of 25–30 cm from the surface.
- 2-3 layers are enough to complete the work.
For minor damage, aerosol cans are indispensable. Polyester primer for cars is applied in a few minutes. After complete drying, the surface is sanded, so that the defect disappears.
