They are obtained during the reaction of polyhydric alcohols and monobasic fatty acids in the presence of carboxylic acids.

In addition to these basic components, special pixotropic and thermo-polymer additives are often mixed in alkyd dyes. Both are necessary to improve the performance of paintwork materials. Paints with pixotropic additives are well retained on the surface and do not form streaks. When used, a layer of exactly the same uniform thickness is obtained. The use of thermopolymer additives allows to reduce the drying time of alkyd paints.

Sometimes these anti-fungal components are also added. Means of this type are best for painting wooden surfaces.

3. The paint is evenly ground over the surface. To perform this operation, it is best to use a roller. Alkyd paints differ quite a large viscosity, and therefore the villi brushes can remain in the applied layer.

On hot surfaces (for example, functioning radiators), it is not recommended to apply alkyd enamels. In this case, the paint will dry too quickly and can go bubbles.
