The effect of vinyl trimethoxy silane as a flame‐retardant agent in ultraviolet curable resin based on palm oil

Palm oil was used as a raw material to produce flame retardant ultraviolet curable resin (POR). Polyethylene glycol with a molecular weight of 400 (PEG 400) was employed as a softening agent to produce coating films with different hardness, while vinyl trimethoxy silane (VTMS) was utilized as a reactive flame‐retardant monomer in the formulation. The resin was successfully cured using ultraviolet radiation with the presence of a photoinitiator. The results showed that the adhesion strength of the coating films was enhanced by the addition of VTMS in the formulation, at a different plasticity when compared with the control sample. From thermogravimetric analysis (TGA), the increment of VTMS content had improved the thermal stability of the films. VTMS also plays a crucial role in improving the flame‐retardant properties of coated wood.
