这篇新论文着重于光理论及与表面纹理的关系,这对于理解应用涂层的消光/哑光机制至关重要.
UV-curable coatings have several advantages such as low environmental impact (from limited use of volatile organic compounds, VOCs), rapid polymerisation rates and increased production rate. To meet the demand for low-gloss aesthetics, which have the ability to embellish textures and surfaces, UV-curable coating industries and researchers have need to adapt. While many processes and technologies have been identified to produce effective coatings, achieving an optimal combination of high mechanical performance and low-gloss aesthetics is still an ongoing challenge.
uv固化涂料具有低环境影响(VOCs的使用有限),聚合速度快,生产速度快等优点.为了满足低光泽美学的需求,它具有修饰纹理和表面的能力,UV固化涂料行业和研究人员需要努力满足这些需求. 虽然已经有许多有效工艺和技术,但实现高机械性能和低光泽美学的最佳组合仍然是一个持续的挑战.
Formulation strategies to induce matting
配方策略诱导哑光
The new paper focuses on light theory and its relationship to surface texture, which are essential to understand the matting mechanism of applied coatings. Formulation strategies to induce matting, including the use of physical matting agents and dispersants as well as modifying the composition of a coating formulation, are summarised. Furthermore, the different processes that lead to surface structuring and enable facile manipulation of gloss are reviewed. Last but not least, new emerging technologies, such as self-matting coatings, which are promising for UV curing applications, are discussed.
