Glass transition temperature (Tg) is one of the important parameters to measure the thermal properties of resin materials, which has an important influence on the quality and properties of epoxy powder coatings. This paper will introduce the resin glass transition temperature test method related to the oil and gas industry standard SY/T0315 of the People’s Republic of China, discuss its application in epoxy powder coating technology, and analyze the applicability of this method.

In SY/T0315, a test method for the thermal characteristics of epoxy powder coatings is specified in detail, including the glass transition temperature test of the resin. The application of this method is not limited to epoxy powder coatings, but also includes the resins that make up the main components, and resin curing agents. This paper will interpret this test method, analyze its principle and steps, and provide readers with the basic knowledge of the glass transition temperature test.

The glass transition temperature of resin is the temperature threshold at which the resin material changes to the glass state, which is directly related to the stability and performance of resin in high temperature environment. As an important anti-corrosion coating, the quality and service life of epoxy powder coating largely depend on the resin material used and its performance in high temperature environment. Therefore, the accurate determination of the glass transition temperature of resin can provide strong support for the development and application of epoxy powder coating.

This article will start from the basic principle of resin glass transition temperature test, introduce the test method steps and precautions. At the same time, combined with practical cases and industry experience, the specific application of the test method in epoxy powder coating technology is discussed. By analyzing the experimental data and results in detail, this paper aims to provide readers with a comprehensive and in-depth understanding, so that they can better use this test method and obtain reliable data in practical engineering.
