Dwight's Shield Series

3% X 3% Alcohol-Resistant Synthetic Foam Concentrate

Introducing Dwight’s Shield Series 3% X 3% alcohol-resistant synthetic foam concentrate. Designed specifically for use with many existing extinguishing equipment systems to extinguish Class B hydrocarbon and polar solvent fuel and deep-seated Class A fires; while being compatible with fresh, sea and brackish water. This biodegradable and non-persistent fluorine-free foam concentrate is a combination of hydrocarbon surfactants and additives that delivers excellent foaming, vapor sealing, extinguishment and burn back properties for attacking and securing both shallow and fuel in-depth fires. Many fluorine-free foams are viscous and often show viscosity increase when in contact with water. Dwight’s Shield Series creates very stable foams with similar viscosity to traditional AR-AFFF foams. This significantly improves storage, handling and long-term stability. Dwight’s formula is free of Siloxanes and secret proprietary blends that include watchlist Prop 65 chemicals seen in other "fluorine-free" foams on the market.


Dwight’s Shield Series 3% X 3% generates stable foams with high fluidity and slow drainage, mimicking fluorinated products. Dwight’s 3% x 3% can be used use with low, medium & high-expansion foam devices and is fully compatible and easily proportioned with standard firefighting equipment, including in-line inductors, self-inducting nozzles, fire truck pumps, bladder tanks, pump skids, balanced pressure systems and more.

Making this a truly a multi-purpose foam; Dwight’s 3% x 3% has excellent wetting ability for effective extinguishment of Class A fuel fires.
