The material
How this grade works and where it fits — exact parameters are defined in the TDS.
This product is an acrylic-modified polysilazane supplied as a one-component system. The modified polysilazane exhibits excellent toughness, hardness, adhesion and resistance to yellowing, together with hydrophobic, anti-graffiti and self-cleaning functionality. The modification improves the water, moisture and mold resistance of the polysilazane resin while also providing high hardness, abrasion and weathering resistance, temperature resistance and high light transmittance. The film withstands 180° bending and remains intact, with adhesion of Grade 0 (cross-cut). Typical applications include automotive coatings, adhesives, electronic sealants, flooring and specialty textile auxiliaries.
Choose this grade where graffiti and markings must wipe off: one-component acrylic-modified anti-graffiti system, >2000 h salt spray, -30…300 °C service.
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.

Storage conditions apply
Service temperature. Intended for outdoor service at ambient temperature; the resin can be adjusted for hardness and toughness to withstand high-temperature service at 350 °C. The temperature resistance of the coating varies according to the temperature resistance of the substrate; the coating offers resistance to cold–heat impact and thermal shock (note: the product supplied differs depending on the substrate).

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
Stainless steel, glass, cast iron, aluminum alloys, titanium alloys, high-temperature alloy steels, glass-ceramic panels, ceramics, photovoltaic glass panels and various fibers. 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. The storage environment must be dry, cool and well ventilated, away from heat and ignition sources. Packaging containers must be kept tightly sealed and placed with care.
Storage temperature must be maintained between 5 °C and 30 °C; the shelf life is 12 months.
Opened, partially used coating must be stored with the container lid tightly resealed.
Mixed (prepared) 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 meets specification.

04
Quality control
Verify film build and adhesion.
Standard process: Surface cleaning → Abrasive roughening → Cleaning and blow-off → Dispense an appropriate amount into the spray cup → EK-M12 spray 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 significant influence on coating performance; the optimum grade is Sa2.5 and the minimum is St3 with no mill scale (GB/T 30790.4-2014), so pay close attention to this step.
Cleaning. Use a dedicated cleaner or degreaser to remove residual oil, dust and other contamination from the roughened surface.
Substrate drying. Before coating, ensure that the substrate surface is dry and clean.
Coating application. For laboratory spray application, a spray gun with a 1.0 nozzle gives better appearance and uniformity. The cured coating is somewhat hydrophobic and oleophobic, so repeated recoating is not recommended.
Curing. After spraying, cure at room temperature: surface-dry after 30 minutes, dry-to-touch after more than 2 hours, through-dry after more than 24 hours. Accelerated heat curing is also possible (150 °C, held for 20 minutes).
Note: This is a one-component curing product; once the container has been opened, use the coating within 6 hours. During longer interruptions in application, clean the application tools thoroughly to prevent them from setting solid. Application in a single spray pass is recommended, with a dry film thickness not exceeding 100 µm.
