NaQ-Z1Wb
Non-aqueous film coat, white or colour
Solvent base ready-mix film coat for moisture sensitive cores.
Application
Solvent base film coating for cores that cannot tolerate an aqueous process. It is supplied white or in your agreed shade, with the same finish characteristics as the aqueous grade at a lower bed temperature.
How it runs
Dispersed in solvent, so the bed runs cooler at around 30 to 35 degrees with a 60 to 65 degree inlet. Solvent handling and area classification apply to the whole stage. Choose this route when the core cannot take an aqueous process rather than as a default, since the aqueous grade is simpler to run.
Build-up and solids are fixed at trial.

Common questions about NaQ-Z1Wb
When should a solvent film coat be chosen over an aqueous one?
When the core cannot take water, not as a default. The aqueous grade is simpler to run and avoids solvent handling, so the solvent route is a decision driven by the core rather than by preference.
What temperature band does it run at?
The cooler of the two. Around 30 to 35 degrees at the bed against a 60 to 65 degree inlet, compared with 35 to 40 and 75 to 80 for the aqueous grades.
