This study investigates the synthesis of γ-Glycidoxypropyltrimethoxysilane (KH-560) modified phenol-formaldehyde (PF) resin and its thermal properties. The modification aimed to improve stability PF by forming covalent linkages through KH-560. successful incorporation KH-560 into was confirmed Fourier Transform Infrared Spectroscopy (FTIR) proton Nuclear Magnetic Resonance (¹H NMR) analyses. Thermal characterization using Differential Scanning Calorimetry (DSC) revealed that led an increase in curing temperature a enhanced exothermic reaction compared unmodified resin. Thermogravimetric Analysis (TGA) demonstrated improvement resin, with higher decomposition temperatures slower rates These findings confirm is effective modifier for enhancing properties
