doolue said:I have a powder dry-bend mixed from polyester epoxy resin, fillers, pigment, other additives... I'm seeking for a method to analyze percentage weight of polyester epoxy content in this powder. So, could you prove an appropriate method to do it?
Thanks
Polyester epoxy content refers to the percentage of polyester and epoxy resins present in a drybend material. It is important to determine because the ratio of these resins affects the properties and performance of the material, such as strength, durability, and chemical resistance.
There are several methods for determining polyester epoxy content, including Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), and gas chromatography-mass spectrometry (GC-MS). Each method has its own advantages and limitations, and the most suitable method will depend on the specific properties of the drybend material.
No, the polyester epoxy content cannot be accurately determined by visual inspection alone. While the presence of certain physical characteristics, such as color and texture, can provide some indication of the resin content, it is necessary to use analytical methods for an accurate measurement.
The polyester epoxy content has a significant impact on the properties of drybend. A higher percentage of epoxy resin can result in a stronger and more rigid material, while a higher percentage of polyester resin can provide greater flexibility and impact resistance. The ratio of these resins can also affect chemical resistance and other performance characteristics.
Yes, there are several standard methods and guidelines available for determining polyester epoxy content in drybend. These include ASTM International standards such as ASTM D5224 for FTIR analysis and ASTM D2584 for TGA analysis. It is important to follow these standardized methods to ensure accurate and reliable results.
