This study looks into the impact of composite coating of epoxy/aluminum hydroxide Al (OH)3 / sodium borate (Borax) on the wooden surface.This work aimed to ascertain the connection between these substances' ignition characteristics and wood surface to study a fire behavior of epoxy composite.The intumescent coating that protects wood surfaces from wildfire is often utilized in places of employment and residence where safety is necessary.The aluminum hydroxide and sodium borate were combined and added to the epoxy resin as a hybrid coating (EAB)wt.%20%, and subsequently implemented by dipping method of wood specimens.GO added to the hybrid coating to improve the scratch resistance of the coating in addition to improving the mechanical properties.This work investigated and discussed the morphology, flammability and mechanical properties of the hybrid coating, hybrid coating's morphology, flammability and mechanical properties.The results demonstrated that the wood surface coated with hybrid coating has a good fireretardant quality, where a clear improvement in fire retardant, a burning rate lowered by 23%, and the hardness increased by 72%, while there was decrease in contact angle with the addition of GO because GO is a hydrophilic.
