Pending flammability regulations and scrutinizing of the environment and health consequences of fire retardants is creating opportunities for novel and greener technologies to reduce the flammability of residential furniture. This presentation will discuss bio-based fire resistant coatings applied to flexible polyurethane foam and fire blocking barrier fabrics. The waterborne coatings were fabricated using Layer-by-Layer assembly and an innovative one- step/one-pot process and were constructed from common natural materials. The coatings caused significant reductions in the flammability (e.g., heat release, ignition propensity, and flame spread) of these substrates. When used in full-scale fire tests, the coated foam caused as high as a 75% reduction in peak, total, and average heat release of furniture.
