New phosphorus-containing epoxy resin from renewable resources

Phosphorus-containing epoxy resins are derived from renewable resources, dictic acid (SA), and are made for flame retardant applications.
developed by the company are characterized by mechanical, solvent, gel content, water absorption, chemical, thermal and flame retardant properties.
synthetic epoxy resins are indicated by physical chemistry and spectral analysis, including Fourier Transform Infrared (FTIR), 1H and 31P MRI spectra

. The curing of epoxy resin mixtures is carried out with polyamide hardeners at a chemical metering ratio of 1:1. The developed coatings are indicated in terms of mechanical, solvent, gel content, water absorption, chemistry, heat and flame retardant properties, and the glass transition temperature and thermal stability of the coatings are analyzed by differential scanning and thermal weight analysis. Respectively.
SA-based epoxy resin improves coating performance
the results show that coatings with SA-based epoxy resins show good mechanical, chemical and solvent resistance. The thermal distribution of the coating indicates that the carbon yield increases with the concentration of SA-based epoxy resin. Extreme Oxygen Index (LOI) and UL-94 tests were performed to understand the flame retardant properties of synthetic coatings, which increased with the concentration of phosphorus-containing epoxy resins.
