Special Note: YX-T505 is a thermosetting product. Products exposed to air should be used up within 12 hours. During long construction periods, cleaning of construction tools should be carried out to prevent the tools from solidifying. It is recommended to complete the application with one spraying or brushing, and the dry film thickness should not exceed 100 μm, otherwise, the coating is prone to sagging. High temperature can improve coating hardness and reduce color difference under the same film thickness.

Operating Instructions |
Remarks |
| Surface roughening |
Before coating, sandblast or grind the substrate surface to remove rust, dust, dirt, etc. adhering to the substrate surface. The best is Sa2.5, and the minimum is St3 grade without scale (GB/T 30790.4-2014). |
Clean substrates may not require this step. |
| Surface Cleaning |
Use a special cleaning agent or degreaser to remove oil, dust, etc. remaining on the abraded surface. |
Affects adhesion, etc. |
| Substrate Drying |
Before coating, ensure that the substrate surface is dry and clean. |
Affects adhesion, etc. |
| Coating Preparation |
Stir the product for 3-5 minutes, weigh according to construction needs, and filter with 120 to 300 mesh for later use. |
|
| Coating Application |
Laboratory spray coating method: 1.0 caliber spray gun, better appearance and uniformity. After curing, the coating has certain hydrophobicity and oleophobicity, but it does not affect repeated coating. |
Clean the gun with alkanes, lipids, ethers, etc. |
| Curing |
Refer to the air spray coating data. During the curing process, the solvent volatilizes and produces a small amount of ammonia gas. Testing shows that Q235B plate material can be cured at 230℃ for 1 hour. For complex substrates, the temperature can be increased or the time can be extended. |
High-temperature testing should use temperature-resistant substrates. |
Product Storage
1. Must be stored in accordance with national regulations. The storage environment should be dry, cool, and well-ventilated, away from heat sources and fire sources. The packaging container must be kept sealed and carefully placed.
2. This product contains ammonia that is physically adsorbed or chemically bonded. Therefore, sufficient preventive measures should be taken during use and material handling. This product is water-sensitive and can react with oxidants, alcohols, acids, and alkalis. Maintain an appropriate distance during storage.
3. The storage temperature should be between 5℃ and 30℃, and the shelf life is 12 months.
4. Unopened and unused coating must be sealed with the lid closed. If necessary, purge with nitrogen before sealing.
5. Unused and prepared coating cannot be recycled and should be disposed of according to local regulations.
6. Products that have exceeded the shelf life can only be used after passing the inspection.
