Applicable substrates of SILZ-150 Polysilazane Resin:
Carbon steel, stainless steel, cast iron, aluminum alloy, titanium alloy, high-temperature alloy steel, microcrystalline glass, ceramics, cement, etc. Note: Different substrates require different coating formulations. Within a certain range, the formulation can be adjusted according to the specific application conditions of the substrate.
Applicable Temperature:
Suitable for outdoor applications below 400℃ and short-term high-temperature applications up to 600℃. The coating’s temperature resistance will vary depending on the substrate’s temperature resistance, and it is resistant to thermal shock and cold shock (Note: Different substrates require different products).
The main characteristics of the SILZ-150 coating are as follows:

Special Notes:
This product is a single-component self-curing product. Once opened, the coating should be used within 4 hours. For longer application intervals, ensure all tools are clean to prevent adhesion. It is recommended to apply in one coat, with a dry film thickness not exceeding 50µm; otherwise, coating performance will decrease.
Standard Application Procedure: Surface Cleaning → Roughening → Cleaning and Blowing → SILZ-150 Treatment → Curing
Instruction Manual
- Roughening: Before coating, grind or sandblast the substrate surface to remove rust, dust, dirt, etc. Roughening significantly affects the coating effect; optimal Sa2.5, minimum St3 (no oxide scale) (GB/T 30790.4-2014), so please pay close attention.
- Cleaning: Use a specialized cleaner or degreaser to remove residual oil, dust, etc., from the roughened surface.
- Substrate Drying: Ensure the substrate surface is dry and clean before coating.
- Coating Mixing: This product is a single-component product. Take an appropriate amount and filter through a 120-mesh sieve as needed.
- Coating Application: For best appearance and uniformity, use a 1.0mm nozzle spray gun in the laboratory. The cured coating has some hydrophobic and oleophobic properties; therefore, repeated application is not recommended.
- Curing: After spraying, the coating should be surface dry in 2 hours, touch dry in more than 3 hours, and completely dry in more than 24 hours at room temperature.
Safety and Storage
- Must be stored according to national regulations. The storage environment should be dry, cool, well-ventilated, and away from heat and fire sources. The packaging container must be kept tightly closed and handled with care.
- The storage temperature should be maintained between 5℃ and 30℃. The shelf life is 6 months.
- Unused paint after opening must be sealed and stored immediately.
- Unused mixed paint cannot be recycled and should be disposed of according to local regulations.
- Products exceeding their shelf life can only be used after passing inspection.
