The material
How this grade works and where it fits — exact parameters are defined in the TDS.
Solvent-free high-viscosity liquid polysilazane resin used as a coating binder and for resin modification. The high viscosity allows films of 0.1–0.4 mm, against the 4–6 µm typical of the low-viscosity grades. It cures by heat, by free-radical initiation or catalytically.
Choose this grade when the job needs real film build rather than a thin functional layer — heavy-duty industrial anticorrosion where 4–6 µm would not survive. Requires an oven step at 150 °C.
Suitable for
Industrial applications within the TDS parameters
Metal, glass, ceramic and stone substrates — per grade
Professional application and curing processes
Not intended for
Consumer or DIY use — industrial B2B supply only
Conditions outside the parameters defined in the TDS
Food-contact or medical use unless explicitly confirmed
Applications
Recommended application areas for this grade, based on its TDS. Application fit is confirmed during technical review.
High-temperature anticorrosion coatings for metal in industrial applications.

Storage conditions apply
Ceramic yield 80–85% by TGA. Pencil hardness 7–9H. Adhesion grade 0. Heat resistance below 500 °C in air; after ceramisation the coating withstands a peak temperature of 1000 °C for extended periods. Shelf life 12 months. Values measured on a 304 stainless steel substrate, blade-coated and air-dried. Both temperature figures are reproduced as given in the technical description.
