We can give you comprehensive advice on how to adapt the suspension/slurry to your requirements precisely.
As well as a high temperature stability, various ceramics also have very good chemical inertness with many molten metals. Pans, moulds or sintering underlays are coated with a suspension/slurry in which the ceramic powder is dispersed to generate a chemical barrier layer.

We supply different ceramic suspensions/slurries which are applied using paintbrushes or sprays as a barrier layer.
With our extensive experience, we can develop suspensions which match the respective requirements precisely.
