|
||
| Fire-Trol GTS-R is a dry concentrate formulation that contains ammonium sulfate as the primary fire retardant salt. It contains a small amount of ammonium phosphate that acts as both a corrosion inhibitor and a retardant salt. GTS-R is a high viscosity (1200-1800 centipoise), gum-thickened product. GTS-R also contains bactericide, additional corrosion inhibitors, and iron oxide color. A batch mixer is used to add the dry concentrate to the proper amount of water. | ||
| Product Type: | High-viscosity, gum-thickened, dry powder; batch mixed. | |
| Qualification: | Qualified for use from a permanent or temporary base and can be applied from a fixed-wing airtanker or helicopter bucket. | |
| Use Level: | 1.66 pounds of dry retardant mixed with 1 gallon of water will produce 1.10 gallons of mixed retardant. Each gallon of mixed retardant contains the equivalent of 1.51 pounds of powder. | |
| Yield: | 1 ton of powder yields 1325 gallons of mixed retardant. | |
| Viscosity: | 1200-1800
centipoise (cP). Field measurement (Marsh funnel) 32-50 sec through the large tip. |
|
| Salt Content: | 15.2
percent by weight active salts: 14.2 percent by weight AS, (NH4)2SO4
and 1.0 percent by weight DAP, (NH4)2HPO4. Field measurement (refractometer): A reading of 16.53 indicates a proper salt content. A reading between 15.0 and 18.25 indicates an acceptable salt content. |
|
| Specific Weight: | 9.07 lb/gal of mixed retardant | |
