Resole phenol-formaldehyde resins have been widely used in various applications due to their outstanding physical and chemical properties of flame retardancy, solvent resistance, thermal stability, and rigidity. However, major disadvantages have been associated with the synthesis of the resins. One disadvantage includes the toxic effects of the phenol and formaldehyde chemical precursors on the human health. In order to create less hazardous materials, the current research was geared towards finding alternate materials to serve as replacements for the phenol precursor of a resole phenol- formaldehyde resin. The current study explored the use of pyridoxine and 3-hydroxypyridine as alternate replacements for the phenolic precursor. Thermogravimetric analysis (TGA) was used to observe the thermal and thermo-oxidative stabilities. The thermal decomposition kinetic parameters of the materials were determined from TGA curves using the Madhusudanan-Krishnan-Ninan (MKN) method.
