Significant savings are achieved by reducing the time curing coatings due to high speeds and because the single-layer drying of powder coating is made once, compared with a multiple-drying in the case of conventional multilayer coatings. Powder coating is cured for 30 minutes. It is possible to obtain thick-layer coatings (due to 100% strength of dry matter) instead of more… (more…)

Fournir – supply, cast) – sheet building material, which usually consists of tightly bonded to the thickness of several thin layers of wood (veneer), and fiber direction in adjacent layers of veneer, usually perpendicular.
