The material

How this grade works and where it fits — exact parameters are defined in the TDS.

EK-M07: This product is an organosilicon (silicone) modified polysilazane supplied as a two-component (A/B) system. The modified polysilazane exhibits excellent toughness, adhesion and resistance to yellowing: the paint film remains intact after a 180° bend. Adhesion is Grade 0, and the hydrophobic anti-soiling performance and insulating voltage resistance are also significantly improved. The unfilled clear coat withstands temperatures above 330 °C; with functional powder fillers it withstands above 600 °C without yellowing. This greatly extends the service performance and range of applications of polysilazane.

Choose EK-M07 for a flexible, hydrophobic silicone-modified system with improved insulating performance.

Storage conditions apply

Service temperature. Suitable for service at temperatures up to 450 °C and for short-term high-temperature exposure at 550 °C. Depending on the temperature resistance of the substrate, the temperature resistance of the coating varies accordingly; the coating withstands hot-cold cycling 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

EK-M07: Carbon steel, stainless steel, cast iron, aluminum alloys, titanium alloys, high-temperature alloy steels, glass-ceramic panels, ceramics, cement and similar materials are all suitable. Note: The coating formulation differs depending on 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. The storage environment must be dry, cool and well ventilated, away from heat sources and open flames. Keep packaging containers tightly sealed and place them with care.

  • Maintain a storage temperature of 5–30 °C; the shelf life is 6 months.

  • Reseal opened containers of unused coating and store them tightly closed.

  • 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.

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 → EK-M07 spraying → Curing

  • Abrasive roughening. Before coating, sand or blast the substrate surface to remove rust, dust, dirt and other contaminants adhering to the workpiece surface. 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 residual oil, dust and other contaminants from the roughened surface.

  • Substrate drying. Before coating, ensure the substrate surface is dry and clean.

  • Coating mixing. This product is two-component; take the required amount and filter it through a 120-mesh screen before use.

  • Coating application. For laboratory spray application, a 1.0 mm nozzle spray gun gives better appearance and uniformity. The cured coating is somewhat hydrophobic and oleophobic, so recoating is not recommended.

  • Curing. After spraying, with room-temperature curing the coating should be surface-dry in 1 hour, touch-dry in more than 2 hours and through-dry in more than 24 hours; accelerated heat curing is also possible (180 °C for 20 minutes).

Note: This product is a two-component curing product; once opened, use the coating within 2 hours. During longer breaks in application, clean the application tools thoroughly to prevent them from setting up. Application in a single spray pass is recommended, with a dry film thickness not exceeding 100 µm.
