How much do you know about the performance testing of paint paste?
Paint color paste is a highly concentrated coating formula, composed of pigments, fillers, dispersants, thinners and other components, which can be mixed and deployed with the base coating in proportion to achieve the desired color and effect. Paint color paste is widely used in construction, furniture, automobile, electrical appliances and other fields, providing more color selection and customized services, as well as the advantages of cost saving and efficiency. The quality and stability of paint color paste have an important impact on color accuracy and coating quality, so it is necessary to carry out quality inspection and control.
The paint color paste needs to test the following properties:
| Performance | Item of inspection |
|---|---|
| Difference of color | The color difference between the paint color paste and the standard color sample |
| Stability of color | Color stability of paint paste, such as color change, stratification, precipitation, etc |
| Liquidity | The flow performance of paint color paste, such as drying time, leveling, etc |
| Degree of viscosity | The viscosity of paint paste |
| Stability | The stability of paint paste, such as suspension, precipitation, etc |
| Other | Such as paint paste resistance to precipitation, hiding power, etc |
Detection method:
Color difference: use color difference meter, optical wavelength meter and other equipment to test the color difference between the paint paste and the standard color sample.
Color stability: through artificial aging test, constant temperature and humidity test and other methods to test the color stability of paint paste.

Others: according to the specific type of paint color paste and testing items, select the appropriate test method and equipment for testing, such as testing the anti-precipitation of paint color paste, hiding power, etc.
The results of these test items can help evaluate the quality and applicability of paint colorants and how well they will perform in practical applications. Test methods and equipment are different according to the specific type of paint paste and test items. The performance test of paint color paste should be carried out in accordance with relevant standards and methods to ensure the accuracy and comparability of test results.
