Works equally well for: BOXBOARD, CARDBOARD, FIBER CONTAINERS, & PAPER INSULATION
P-3000 Paper Shield™ Is the only brand trusted to take on extreme heat, such as holding a blowtorch to a thin paper board, without worry. An excellent high grade fire retardant chemical for all paper and fiber surfaces.
As with all Universal Fire Shield™ products, the Paper Shield™ formula reacts to reverse the combustible gases and tars to a non-combustible carbon char; nitrogen and carbon dioxide. This reaction prevents flame spread and ignition, as well as regeneration.
