The material
How this grade works and where it fits — exact parameters are defined in the TDS.
This product uses polysilazane as the film-forming binder and can be cured either at room temperature or with heat. Dielectric strength is ≥10⁵ V/mm, and the coating withstands long-term service in 400-500 °C environments without cracking, flaking or discolouration. Pencil hardness is ≥5H, and the coating offers excellent abrasion resistance, a dense waterproof film, salt-spray corrosion resistance and ageing resistance. On curing it forms covalent bonds with the substrate; this chemical bonding greatly increases the mechanical strength of the coating.
Application fields: 1. Insulating installations of all kinds, electric motors, electrolysis, flooring, energy storage, batteries, electric furnaces; 2. Electromagnetic induction, aerospace equipment, military equipment, high-tech equipment; 3. Electric heating equipment, electric power equipment, substations, converter stations, electrical engineering; 4. Heat-generating installations, optoelectronic installations, thermal-energy equipment and related fields.
Choose this grade for combined insulation and corrosion protection to 500 °C service: ≥10⁵ V/mm dielectric strength, curable at room temperature or 180 °C.
Final fit is confirmed during technical review — send your substrate, operating environment and application process, and the team will confirm this grade or point you to a closer one.

Substrates & storage
Compatibility and handling essentials — confirmed per grade in the TDS and SDS.
Suitable substrates
Steel and stainless steel
Aluminium and other metals
Glass and ceramics
Stone and mineral surfaces
Aluminium sheet, carbon steel, stainless steel, cast iron, aluminium alloys, titanium alloys, high-temperature alloy steels and similar materials are all suitable. Note: the coating formulation differs according to the substrate; within a certain range it can be adjusted to match the substrate and its service conditions.
Storage, packaging & transport
Store in accordance with national regulations in a dry, cool, well-ventilated place, away from heat and ignition sources. Keep packaging containers tightly closed and place them with care.
Maintain the storage temperature between 10 °C and 30 °C; the shelf life is 6 months.
Once opened, reseal containers tightly to store any unused coating.
Mixed coating that is not used up cannot be reclaimed; dispose of it in accordance with local regulations.
Product past its shelf life may be used only after testing confirms it still conforms.

Application process
General guidance — exact parameters are provided in the TDS and Application Guide.
01
Surface preparation
Clean, degrease and prepare the substrate.
02
Application
Spray, dip or wipe depending on grade.
03
Curing
Cure per the TDS conditions.
04
Quality control
Verify film build and adhesion.
Standard process: Surface cleaning → abrasive roughening → cleaning and blow-off → spray/blade application → curing
Abrasive roughening. Before coating, sand or blast the substrate surface to remove rust, dust, dirt and other contamination adhering to the workpiece. Surface roughening has a major influence on coating performance: Sa2.5 is optimal and St3 with no mill scale is the minimum (GB/T 30790.4-2014), so give this step full attention.
Cleaning. Use a dedicated cleaner or degreaser to remove oil, dust and other residues remaining on the roughened surface.
Substrate drying. Before coating, ensure the substrate surface is dry and clean.
Coating mixing. This is a two-component product: measure out the required quantity at the specified mixing ratio, stir until thoroughly homogeneous, and filter through a 180-mesh screen before use.
Coating application. For laboratory spray application, a spray gun with a 1.0 nozzle orifice gives better appearance and uniformity.
Curing. After spraying, cure at room temperature: surface-dry in 1 hour, touch-dry in more than 2 hours, through-dry in more than 24 hours. Accelerated heat curing is also possible (hold at 180 °C for 30 minutes).
Note: This is a two-component self-curing product; use the mixed coating within 4 hours. During longer breaks in application, clean application tools thoroughly to prevent them from setting up. For repeated spray passes, an interval of 5-8 minutes is recommended, with each pass below 40 µm thick.
