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 material and can be cured either at room temperature or with heat. With a dielectric strength of ≥10⁵ V/mm, it can serve long-term in 400–500 °C environments without cracking, flaking or discoloration. Pencil hardness ≥5H; the coating offers excellent abrasion resistance, puncture resistance, dense waterproofing, salt-spray corrosion resistance, resistance to chemical media and aging resistance. On curing it forms covalent bonds with the substrate; this chemical bonding greatly increases the mechanical strength of the coating.
Application areas: (1) insulating and voltage-withstanding 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, power equipment, substations, converter stations, electrical systems; (4) heat-generating installations, optoelectronic installations, thermal-energy equipment and related fields.
Choose this grade when you want the insulating system colour-coded: the blue-film version with ≥10⁵ V/mm and -30…500 °C service makes coverage visually checkable.
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
Aluminum plate, carbon steel, stainless steel, cast iron, aluminum alloy, titanium alloy, high-temperature alloy steel and other materials are all suitable. Note: the coating formulation differs for different substrates; within a certain range it can be adjusted and matched to the substrate and its service conditions.
Storage, packaging & transport
Store in accordance with national regulations, in a dry, cool and well-ventilated environment away from heat sources and open flames. Packaging containers must be kept tightly closed and placed with care.
Maintain the storage temperature between 10 °C and 30 °C; the shelf life is 6 months.
Coating that has been opened but not used up must be resealed under the container lid and stored sealed.
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 is still acceptable.

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 coating → Curing
Abrasive roughening. Before coating, sand or grit-blast the substrate surface to remove rust, dust, dirt and other matter adhering to the workpiece surface. Roughening strongly affects 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 cleaning agent 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: take an appropriate amount of coating at the specified mixing ratio, stir until thoroughly and uniformly mixed, 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, for room-temperature curing allow 1 hour to surface-dry, more than 2 hours to touch-dry and more than 24 hours to dry through; rapid heat curing is also possible (hold at 180 °C for 30 minutes).
Note: This product is a two-component self-curing product; use the mixed coating within 4 hours. For longer application intervals, clean application tools promptly to prevent them from setting solid. The recommended interval between successive spray passes is 5–8 minutes, with each pass below 40 µm thick.
