Abstract

Inspired by an improved accelerated weathering protocol to anticipate Florida exposure behavior of coatings, designated as new protocol (NP),¹ which is implemented in the ASTM D7869-13 standard, a weathering protocol is proposed to replicate the exposure in the temperate climate in Stuttgart (Germany). This protocol, designated as ZykStuttgart, has been developed by adapting the steps proposed by the NP to the climate in Stuttgart. Therefore, weather data from Homestead (Florida/USA) and Stuttgart has been analyzed and compared. Numerical simulations of water uptake and hygro-thermal stresses for model coatings were performed for varying cycle designs and using time-resolved outdoor weather data to support protocol development.

特定地点涂层的风化：1 .中欧温带气候的加速协议和数值模拟

在ASTM D7869-13标准中实施了一项改进的加速风化协议，以预测涂料的佛罗里达暴露行为，该协议被称为新协议（NP） 1，受到该协议的启发，提出了一项风化协议，以复制斯图加特（德国）温带气候下的暴露。该协议被命名为ZykStuttgart，是通过调整NP提出的步骤来适应斯图加特的气候而制定的。因此，对来自Homestead （Florida/USA）和Stuttgart的天气数据进行了分析和比较。在不同的循环设计下，对模型涂层的吸水率和湿热应力进行了数值模拟，并使用时间分辨的室外天气数据来支持方案的制定。
