A method of making a UV curable hardcoat composition uses a strip-free process and produces hardcoats having good scribed tape-pull adhesion, high resistance to scratching and a low delta taber haze after abrading for 500 cycles with a 500 gram weight. UV curable hardcoat compositions are also provided which contain high solids contents and high mole percentages of photoinitiator. Compositions containing methoxypropanol as a water miscible alcohol and methylbenzoylformate as a photoinitiator exhibit high taber hardness and can be made by processes which obviate the need for a time and energy consuming solvent-strip step. The processes are not only shorter, but safer than processes which include a solvent-strip step.
一种紫外线固化硬涂层组合物的制造方法采用无剥离工艺,生产出的硬涂层具有良好的划线拉带附着力、高抗划伤性以及在以 500 克重量进行 500 次循环研磨后的低 delta taber 雾度。此外,还提供了含有高固体含量和高摩尔百分比光
引发剂的紫外线固化硬涂层组合物。含有甲氧基
丙醇(作为
水溶性醇)和甲基
苯甲酰甲酸酯(作为光
引发剂)的组合物具有很高的塔伯硬度,并且可以通过免去耗时耗力的溶剂剥离步骤的工艺制成。与包含溶剂剥离步骤的工艺相比,这种工艺不仅时间短,而且更安全。
