For many years the name of the clear has been associated with the sealer, and traditionally the painters used this composition to paint the wooden doors that during the process clear was mixed with the sealer and consumed with the advancement of science and technology and over time the mixing of these two materials is still in progress and only the methods of use of this material have undergone a little change, for example the use of a sealer has been changed with a brush and its application by pistols and rollers has become commonplace and the only thing that has changed and that didn't change was the mixing of the sealer and clear. Mixing the sealer with the clear or applying the sealer on it causes the microscopic surface to be filled in a heterogeneous manner, resulting in a poor adhesion of the polyester to the sealer.
Application:
This coating (on epoxy and polyurethane cycles) is used where attractive appearance and good resistance to corrosion factors are required.
