La serigrafia è un processo importante nella produzione del vetro: consiste nell’applicazione di pigmenti ceramici monocomponenti su vetro temperato, seguita dalla cottura durante il processo di tempra o piegatura a temperature elevatissime. Questa operazione assicura ottima adesione, resistenza meccanica, durabilità e protezione dai raggi UV, caratteristiche essenziali per i vetri automotive esposti a condizioni esterne.
Screen printing is an important process in glass manufacturing: it involves applying single-component ceramic pigments onto tempered glass, followed by firing during the tempering or bending phase at very high temperatures. This operation ensures excellent adhesion, mechanical strength, long-term durability, and UV protection—essential features for automotive glass exposed to outdoor conditions.
Some practical functions that provide these fundamental characteristics for glass subjected to extreme environmental conditions include:
-
excellent adhesion to the glass
-
high mechanical resistance
-
long-lasting durability
-
UV protection
Functions of the Screen-Printed Band
In the automotive sector, screen printing is mainly used to apply the protective black band around the perimeter of the glass, with both aesthetic and technical purposes. Specifically, it allows manufacturers to:
-
Shield integrated components such as sensors, heating elements, and wiring
-
Preserve the polyurethane adhesive by protecting it from direct sunlight
-
Customize windshields and rear windows with logos, codes, or specific graphic elements
