National Foam HydroAttack Class A Wetting Agent Concentrate
National Foam HydroAttack Class A Wetting Agent Concentrate is a high-performance firefighting additive designed to enhance water penetration and efficiency for faster suppression of Class A combustible fires while reducing water usage.
PRODUCT DESCRIPTION
HydroAttack concentrate by National Foam produces a cost-effective Class A wetting agent that improves the penetrating properties of water for enhanced firefighting capability. It reduces the surface tension of water, helping it to soak into surfaces and reach deep-seated fires, and it improves the water’s adherence to vertical surfaces to assist cooling.
These enhancements can reduce the amount of water and time required for knockdown and extinguishment of a Class A fire versus the application of water alone.
This wetting agent is intended for use as a wetting agent in a 0.1% to 1% freshwater solution (0.1 to 1 part concentrate in 99 parts of water). Dilution in salt or brackish water is not recommended. The concentrate may be proportioned with most conventional, calibrated industry proportioners.
Applications
- Structural
