AQUAFOM WETTING AGENT (WA)
TU 2481-025-72410778-2012
General
Purpose and scope
Aquafom WA wetting agent is a synthetic highly effective agent for extinguishing forest and natural fires, as well as Class A fires. It is an aqueous solution of hydrocarbon surfactants with stabilizing additives.
The Aquafom WA wetting agent has the following types depending on the volume concentration in the premix:
- «Aquafom WA» 0,5%;
- «Aquafom WA» 1,0%.
Depending on the shelf life, these modifications are divided into two subgroups:
- «Aquafom WA»-18 – shelf life is 18 months;
- «Aquafom WA»-60 – shelf life is 60 months (5 years).
Mechanism of action: improving penetration of the foam concentration solution into fibrous hydrophobic materials due to reducing the interracial tension in the wetting solution, compared with water. The use of wetting solutions reduces the water consumption by 35-50% and significantly increases the effect of water use.
Aquafom WA penetrates faster and easier into the burning substances mass and wets a large area.
Aquafom WA is the most effective:
- when extinguishing combustible materials poorly wetted with water (wood, coal, paper, peat, cotton, etc.);
- in extinguishing forest fires;
- to increase the efficiency of water firefighting;
- for dust suppression and dust deposition;
- in sprinkler and deluge fire extinguishing installations.

Environmental protection
The Aquafom WA wetting agent is a biodegradable product capable of complete biodegradation.
No secondary hazardous compounds are formed during the manufacturing and use of the wetting agent.
The Aquafom WA wetting agent is allowed to discharge into industrial wastewater when diluted with water to the marginal permissible concentration of surface-active substances (surfactants) of 20 mg/l (in terms of active substance). The aqueous foam solution can be discharged to biological treatment plants without local wastewater treatment by physical and chemical methods.
