How to avoid the problem of poor stability during UV ink storage? 1. UV inks are prone to cross-linking when exposed to light or heat, so direct light exposure should be avoided during use, and long-term storage in an environment above 30C is not allowed. It must be ventilated below 16-28C and protected from light. 2. To increase the photocuring speed, adding too much photoinitiator will also affect the stability of UV ink. Therefore, the addition of excess photoinitiator should be avoided. 3. Improper use of UV inks produced by different manufacturers can also cause changes in the stability of UV inks. Therefore, when the ink needs to be mixed and used, it must be tested first, and then mixed and used only when there is no reaction. INCHEE FURNITURE CO.,LTD , https://www.inchee.com
