|Flame-retards sawdust, wood, thatch and wood chips require undiluted BURN BARRIER™ W concentrate. BURN BARRIER™ W is also tested to be effective on natural foliage & unfinished wood products. ASTM E-84 Class A 125/SF/gallon of concentrate.
BURN BARRIER™ W is not as effective on plastic or synthetic fibers as it is on natural fibers or blends. BARRIER W™ will flame-retard all recommended items, but will not prevent charring. BURN BARRIER™ W is colorless, orderless and non-toxic, but is not recommended for ingestion. It will usually not affect the look, feel or ventilation qualities of any material treated. A test application on a small sample must be made prior to treatment if color, texture and appearance is critical. BURN BARRIER™ W will not normally lose effectiveness from age or from wearing off, but will lose effectiveness after rain if used outdoors. Materials treated may withstand drycleaning. BURN BARRIER™ W will usually not affect the shade or color fastness of textile, paper or dyes, normally not effected by water.
|Testing for color-fastness should be done to confirm that the wood will maintain it’s color and
beauty after it is treated.
Above tests are equivalent to UL723, ANSI No. 2.5, NFPA No. 255 and UBC No. 42-1.
