YX-T702 is a single-component, room-temperature curing product. Products exposed to air should be used within 12 hours. During prolonged construction periods, cleaning of tools should be carried out to prevent tools from setting. It is recommended that one spray or brush coat be applied, and the dry film thickness should not exceed 120 micrometers, otherwise the coating may sag. High temperature can increase the hardness of the coating at the same film thickness, and reduce color difference.

Operating Instructions |
Remarks |
| Surface Roughening |
Before coating, grind or sandblast the substrate surface to remove rust, dust, dirt, etc. attached to the substrate surface. Optimal Sa2.5, minimum St3 grade without scale (GB/T 30790.4-2014). |
This operation can be omitted for clean substrates. |
| Surface Cleaning |
Remove oil, dust, etc., remaining on the napped surface using a special cleaning agent or degreaser. |
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 a certain water and oil repellency, 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 placed carefully.
2. This product contains physically adsorbed or chemically bonded ammonia; therefore, sufficient preventive measures should be taken when using and handling related materials. 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 mixed coating cannot be recycled and should be disposed of according to local regulations.
6. Products that have exceeded the shelf life can be used only after passing the inspection.
