It is best to use these formulations if necessary to perform a primary coating.
Nitrocells are also classified as furniture varnishes. To prepare them take in different proportions of colloxin, various plasticizers, as well as resins.
Such formulations dry quickly enough, and besides, they have good adhesion to the working surface, give it increased strength.
The disadvantages of such varnishes include low environmental performance and the presence of an unpleasant odor, which excludes their use in the children's room.
An epoxy coating is also applied to the furniture, which has a high abrasion resistance and various mechanical effects.
Polyurethane varnishes are very popular, which are widely used not only in the furniture sector, but are also very often used for interior finishing.
