Choice of coating:

The choice of the coating should be done in careful manner, since a direct impact on the final performance, Appearance, weathering resistance, Chemical resistance, on application techniques, spray (enamel) or electrodeposition (powder), and hence the cost the entire process.

Usually the performance required of a paint product are:

Resistance to environmental conditions and operating

duration

Flexibility and abrasion resistance

Excellent resistance to the removal of graphite

Taking into account the “performance”, let’s see some peculiarities of coatings such as, categories, features, components “resins”.

Categories of coating materials;

Those most used are:solvent-based powder

Characteristics of coating materials;

The classification as a result of the characteristics required of a coating, are essentially:

color

finish

Adhesion to the substrate

Physical and mechanical properties

Resistance to chemicals

Resistance to corrosion

durability

Main components of coatings;

Among the main components the most important one is the resin, not only for its quantity which can reach even 40% of the weight, but in that it confers to the coating the chemical, mechanical, physical.

The resins are usually used for the composition of the coatings are:

acrylic resins

epoxy resins

polyurethane resins

amino resins

polyester resins, saturated – unsaturated

phenolic resins

As an important part of our process, in the next chapter we further uses and application of various coating products.
