Boron added to urea formaldehyde (UF) resin during manufacture of board from waste tea leaves was combined with a fire-retardant coating system containing boron to further reduce combustibility. Boric acid (BA) and borax (BX) were used as boron compounds separately or in a mixture of 5:1 (BA:BX, w/w) in aqueous solutions of UF resin. A BA + BX mixture was also added to a 40% aqueous solution of trimethylolmelamine (TMM) (as a binding agent) and applied to the board surface. Fire-retardant properties were determined according to the Japanese Industrial Standard JIS A 1322.
