In ceramic production, the use of digital glues for glaze and grit applications has almost completely replaced the spray/airless application system.

Even if each glue acts differently on glass powders and grits, there are two main categories that must be considered:

solvent-based digital glues (based on non polar solvents) and water-based digital glues (based on polar solvents and water).

The episode opens with a general introduction on the chemical nature of these products, then offering two important focuses on the operation and mechanisms of action that they develop on the raw tile support. Both with similarities and differences.
