Benign design intumescent flame-retarding aliphatic waterborne polyester coatings modified by precipitated silica aerogel and aluminum powder

The organic-inorganic hybrid intumescent flame retardant coatings (IFRCs) is an efficient and ecological strategy to obtain excellent fireproof performance. The benign design on aliphatic waterborne polyester (AWP)-based IFRCs is modified by silicon-based aerogels and aluminum powder simultaneously,...
