1. Choose the right type of resin
Before using Polyester Resins For HAA Based Formulations, you first need to choose the right type of resin according to the specific application requirements. The table lists a variety of different types of resins, such as YZ9813, YZ9819, YZ9848, etc. Each resin has its own specific acid value, viscosity, glass transition temperature (Tg) and curing time parameters. For example, YZ9813 is suitable for occasions that require good leveling, while YZ9819 performs well in weather resistance and anti-yellowing properties. The selection should be based on the final use and performance requirements of the coating.
2. Prepare and mix the resin
When using Polyester Resins For HAA Based Formulations, the correct preparation and mixing steps are essential. First, make sure that the resin and curing agent are mixed in the specified ratio, such as 95/5 or 96/4 as shown in the table. When mixing, use appropriate stirring equipment to ensure that the resin and curing agent are fully and evenly mixed to avoid problems such as uneven curing or unstable performance.
3. Control the curing conditions
The curing conditions of Polyester Resins For HAA Based Formulations have an important impact on their final performance. The table lists the recommended curing temperature and time for each resin, such as YZ9813 and YZ9819 are cured at 180°C for 12 minutes, while YZ9848 is cured at 165°C for 12 minutes. In actual operation, the curing temperature and time should be strictly controlled to ensure that the resin is fully cured and achieve the expected coating performance.
4. Pay attention to the characteristics of the resin
Each Polyester Resins For HAA Based Formulations has its own unique characteristics, which determine its performance in different applications. For example, YZ9848 has the characteristics of low-temperature rapid curing, good water boiling resistance, and frost resistance, and is suitable for the preparation of various orange granular powders; while YZ9860 has the characteristics of building material grade, good mechanical properties, and good storage stability, and is suitable for occasions that require high mechanical properties and long-term storage stability. These characteristics should be fully considered when using to ensure that the final effect of the coating meets the requirements.
