First, the storage knowledge of paint
The storage stability of coatings is a key index of coatings. Therefore, during storage, storage should be carried out in stages according to the production date and storage time of the coating product, so as to prevent the coating from becoming thicker, precipitated, and crusted due to excessive storage time. Blocking, discoloration, flocculation and other adverse phenomena, in serious cases, it may even cause the paint to gel and be scrapped. The general paint storage period is one to one and a half years, and there are also paint varieties with a storage period of half a year. Therefore, during the storage process, it should be constantly checked. The storage time indicated on the packaging of the paint should be used in time to prevent the performance of the paint from being affected by the expiration date.
Second, the storage knowledge of paint
| serial number | content |
| 1 | There must be a special warehouse for the storage of paint, and a special person is responsible. Fire is strictly prohibited in the warehouse, and unrelated personnel are not allowed to enter |
| 2 | It is not allowed to pile up paint materials in the open air, and it is strictly forbidden to store paint in open containers |
| 3 | The packaging container of the coating should be well sealed, and the storage temperature should be within the range of 5~30°C, with good ventilation and no direct sunlight |
| 4 | Powder coatings are afraid of heat and humidity, and should be stored in a warehouse with low temperature and dryness without direct sunlight. |
| 5 | Shorten the storage period of paint as much as possible, and use it on a first-come, first-served basis. If the storage period exceeds the storage period, it will be used according to the quality after re-inspection or scrapped. |
| 6 | During the transportation of organic solvents or powder coatings, the accumulation of electrostatic charge fields should be strictly prevented |
| 7 | After each batch of paint enters the factory, it should be sampled and inspected, and then used after passing the test. The quality is stable and commonly used, and it should be regularly sampled and inspected. |
| 8 | For two-component coatings, they need to be stored in different categories to prevent mixing |
