In order to prevent PU color paste from fading, you can take the following measures:
Choose high-quality raw materials: Choose high-quality PU color paste raw materials to ensure they have good light resistance and antioxidant properties, fundamentally reducing the possibility of fading.
Add antioxidants: When producing PU color paste, you can add an appropriate amount of antioxidants to improve the antioxidant performance of PU color paste and delay the color fading.
Use UV absorbers: Adding a certain amount of UV absorbers to PU color paste can effectively absorb UV rays, reduce UV damage to color, and delay the fading process.
Correct storage and use: During the production and storage process, avoid long-term exposure of PU color paste to sunlight or strong light, and also minimize direct sunlight time during use.
Regular maintenance: Regular maintenance of PU products, using special care products for cleaning and maintenance, can extend the color retention time of PU color paste.
Processing process control: During the production and processing of PU products, factors such as temperature, humidity, and light must be controlled to avoid damage to the PU color paste during processing.
