FireCellCoat provides a novel approach for durable, high-performance fire-retardant materials based on sustainable resources.
FireCellCoat develops bio-inspired, fire retardant wood coatings based on microfibrillated cellulose (MFC) that protects wood-based building products in interior and exterior applications. The coatings potentially have lower environmental impacts and lower or equal life cycle costs compared to conventional fire retardant coatings. Additionally, they fulfil the technical requirements for interior wall paints and exterior wood coatings.
FireCellCoat's approach is to construct a novel fire-retardant structure draws inspiration from Canary pine bark architecture and chemistry - nature's outstanding solution against fire. By designing a similar type of macro-scaled multilayer structure we will develop a wood coating that delays ignition and fire propagation. To achieve this, MFC is used in combination with inorganic components. This is complemented by a chemical approach involving copolymerization techniques to protect the fire-retardant material against leaching from the coatings. The coating can be applied by spray or brush and is well suited for improving the fire properties of wood-based materials as it reduces the access of oxygen to the surface, thus significantly inhibiting combustion.
