Applicable Substrates:
Carbon steel, stainless steel, cast iron, aluminum alloy, titanium alloy, high-temperature alloy steel, microcrystalline glass, ceramics, cement, etc.
Note:
Coating formulations differ depending on the substrate. Within a certain range, adjustments can be made according to the different application conditions of the substrate. Applicable Temperature: Maximum withstand temperature 500℃, can be used continuously at 350℃. Coatings compounded with heat-resistant nanofillers can withstand direct erosion from flames or high-temperature airflows. The temperature resistance of the coating will vary depending on the temperature resistance of the substrate. It is resistant to thermal shock and cold shock (Note: Products for different substrates will vary).

Special Notes:
This product is a single-component thermosetting product. Once opened, the coating should be used within 24 hours. For extended application intervals, ensure application tools are thoroughly cleaned to prevent adhesion. It is recommended to apply in one coat, with a dry film thickness not exceeding 15µm; otherwise, coating performance will degrade.
Standard Application Procedure: Surface Cleaning → Roughening → Cleaning and Blowing → PA151 Treatment → Curing
Procedure Description:
1. Surface Roughening: Before coating, grind or sandblast the substrate surface to remove rust, dust, dirt, etc. Surface roughening significantly affects the coating effect; optimal Sa2.5, minimum St3 (no oxide scale) (GB/T 30790.4-2014), so please pay close attention.
2. Cleaning: Use a specialized cleaner or degreaser to remove residual oil, dust, etc., from the roughened surface.
3. Substrate Drying: Ensure the substrate surface is dry and clean before coating.
4. Coating Mixing: This product is a single-component product. Take an appropriate amount and filter through a 120-mesh sieve as needed.
5. Coating Application: In laboratory spraying, a 1.0 caliber spray gun provides better appearance and uniformity. The cured coating has some hydrophobic and oleophobic properties; therefore, repeated coating is not recommended.
6. Curing: After spraying, allow the surface to dry for 10 minutes, then cure at 180℃ for 60 minutes (for coatings below 400℃), or at 250℃ for 60 minutes (for coatings above 400℃).
Safety and Storage
1. Must be stored according to national regulations. The storage environment should be dry, cool, and well-ventilated, away from heat and fire sources. Packaging containers must be kept tightly sealed and handled with care.
2. Storage temperature should be maintained between 5℃ and 30℃. Shelf life is 12 months.
3. Unused paint after opening must be tightly sealed and stored.
4. Unused mixed paint cannot be recycled and should be disposed of according to local regulations.
5. Products exceeding their shelf life can only be used after passing inspection.
