The material
How this grade works and where it fits — exact parameters are defined in the TDS.
This product uses room-temperature-curing polysilazane as the film-forming binder, filled with titanium dioxide, phosphates and inorganic silicon powder. The coating withstands temperatures above 600 °C and offers high hardness, a dense waterproof film, resistance to acid and salt-spray corrosion, and resistance to ageing. As a high-temperature coating based on a novel organic–inorganic hybrid system, it combines multiple composite materials, including high-temperature molecular materials, anti-rust fillers, ultrafine powders and an organic polymer dispersion. After curing, the filler particles pack densely within the resin and the finish shows a degree of gloss. The raw materials are primarily ionic compounds; on curing they form covalent bonds with the substrate, and this chemical bonding substantially increases the mechanical strength of the coating.
Typical applications: 1. Electric heaters, boiler components, piping, valves, heat exchangers, radiators; 2. High-temperature devices and high-temperature sensor components; 3. Surfaces of metallurgical equipment, moulds and foundry equipment; 4. Electric heating elements, tanks and enclosures; 5. Small household appliances and kitchenware (burner caps, electric rice cookers), etc.; 6. High-temperature components in the chemical and metallurgical industries.
Choose this grade as the light-coloured, titanium-dioxide counterpart of EK-D04: room-temperature curing, -30…600 °C service — visible or light surfaces without an oven.
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
Carbon steel, stainless steel, cast iron, aluminium alloys, titanium alloys, high-temperature alloy steels, glass-ceramic panels, ceramics, cement 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 5 °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.

Standard process: Surface cleaning → abrasive roughening → cleaning and blow-off → EK-D05 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 300-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 20 minutes).
Note: This is a two-component, room-temperature-curing product; use the mixed coating within 6 hours. During longer breaks in application, clean application tools thoroughly to prevent them from setting up. Application in a single spray pass is recommended, with a dry film thickness not exceeding 50 µm; otherwise film performance will be reduced.
