The material
How this grade works and where it fits — exact parameters are defined in the TDS.
Solvent-based low-viscosity liquid polysilazane resin for heat-resistant, hydrophobic, easy-clean and corrosion-resistant coatings. It reaches full cure in a single day, faster than any other grade in the range, and gives the highest water contact angle among the ambient-curing grades. Note that this is a solvent-based grade — active content is 50–60%.
Choose this grade when parts have to go back into service quickly — full properties in one day rather than the three to seven days typical of the range. Being solvent-based, it needs ventilation and handling appropriate to solvent systems.
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.
Anti-fouling and ablation-resistant coatings for automotive interiors and exteriors. High-temperature anticorrosion coatings for chimneys, high-temperature pipework and chemical process equipment. High-temperature antioxidation coatings in the smelting industry.
