Applications |
KEYCURE 8028 may be used alone in combination with other suitable photoinitiators (such as Chemacure PI-184 PI 6022) fUV curable inks varnishes fapplications on paper, wood, metal plastic materials. Its high absorbance makes it especially suitable fUV curable inks pigmented coatings. KEYCURE 8028 is particularly indicated fthe photopolymerisation of UV curable systems when high reactivity, low curing odour low yellowing are required. KEYCURE 8028 recommended concentration: 0.1-7.0% KEYCURE 8028 recommended applications: |

用途 |
KEYCURE 8028 可以单独使用或与其他合适的光引发剂的组合（如chemacure PI-184和PI 1212）应用于纸张，木材UV固化油墨和清漆，金属和塑料材料。其高吸光度使得其特别适合于UV可固化油墨和着色涂料。 具有反应活性高，低气味，低黄变固化要求的特点。 建议浓度：0.1-7.0% |
|
|
推荐应用： |
KEYCURE 8028 用于下列用途：透明漆(用于木材、塑料、纸张、金属、光导纤维)、油墨(丝网、胶印、柔性版、喷墨)和食品包装。 按重量计，KYCURE 8028的使用量为2.0-5.0%。
多功能光引发剂，极低气味，低迁移，不泛黄，高溶解度，完全替代了ESACURE 150和ESACURE，或Irgucure 754。 强烈建议我们在敏感的包装，如包装在食品，化妆品和药品。
KEYCURE -8028固化速度比184倍快3.5倍。 我们的欧盟伙伴现在使用8028代替369，但只能在表面固化。配方器使用8028+TPO代替369in深度固化系统。
此外，还推荐在LED固化中使用8028作为光敏化增强剂. |
