Standard Test Method for Gel Time of Thermosetting Coating Powder 热固性涂料粉末凝胶时间的标准测试方法
发布日期: 2025-01-01
1.1 该测试方法确定热固性涂料粉末在指定温度(例如204°C(400°F))下在抛光金属表面上凝胶所需的时间长度。凝胶时间的测定是涂料粉末表征和质量控制的一种非常简单的方法。然而,该方法测定的凝胶时间在实际应用中与涂料粉末固化的时间没有直接关系。 1.2 本标准并不旨在解决与其使用相关的所有安全性问题(如果有)。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。 1.3 本国际标准是根据Wor发布的关于制定国际标准、指南和建议的原则的决定中确立的国际公认的标准化原则制定的ld贸易组织技术性贸易壁垒委员会。 ======意义和用途====== 4.1 该测试方法可用于选择在规定温度下在所需时间内胶凝的涂料粉末。该方法对于确定固化时间没有用。
1.1 This test method determines the length of time a thermosetting coating powder takes to gel on a polished metal surface at a specified temperature, such as 204 °C (400 °F). The determination of the gel time is a very simple method for the characterization and quality control of coating powders. However, the gel time determined by this method is not directly related to the time for the coating powder to cure in practical applications. 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 This test method is useful for selecting coating powders that gel in the desired time at the specified temperature. The method is not useful for determination of cure time.
