Wetting Agents

are fire water additives which lower the surface tension of water and reduce the interface tension between water and solids.

Wetting Agent

is a wetting agent based on synthetic, surface active components. Used as fire water additive the wetting effect of UltraWet® is considerably higher than conventional foam concentrates at the same concentration. The UltraWet® solution penetrates the surface of materials which are difficult to wet quickly and thoroughly. The use concentration of only 0.1% reduces the environmental impact and allows for a rapid and complete bio degradation.

Foam concentrates suitable for use as wetting agent

STHAMEX®
comprises our range of synthetic detergent foam concentrates, which are designed for generating low, medium and high-expansion foam. Interface-active ingredients, foam stabilisers and antifreeze characterise the composition of these powerful, reliable and fluorine-free foam concentrates.

STHAMEX®-K 1%
is a highly concentrated synthetic detergent foam concentrate with a 1% induction rate to water. The low induction rate effectively triples the service time when compared with 3% induction rate foam concentrate.

0 °C ≤ 30 mm2/s
min. use temperature ≤ 110 mm2/s
Frost-resistance -6 °C / -15 °C / -20 °C / -25 °C

Primary use: Municipal fire services, power stations, industry, plastics industry, recycling plants, maritime, aviation, mining

Main application: non-polar hydrocarbons (fire class B) and solvents, plastics, recyclables, tyres, solid material fires (fire class A).

Installations and equipment: Hollow stram nozzles, low-expansion foam installations, low-expansion foam monitors, low-expansion foam branch pipes, medium-expansion foam branch pipes, high-expansion foam generators, CAFS

All synthetic detergent foam concentrates are fluorine-free, physiologically safe when used as intended, and 100% biodegradable.

STHAMEX® -class A
is a new, refined, highly concentrated foam agent based on foam-forming active ingredients, which are specially designed for extinguishing solid fuel fires (fire class A), as well as for use with compressed air foam system (CAFS). Upwards from 0.1% proportioning rate, STHAMEX® -class A is suitable for use as a wetting agent and, upwards from 0.3%, for CAFS applications. For extinguishing liquid fires (fire class B), the induction rate is 0.5%.

STHAMEX®-class A Classic
is a highly concentrated foam agent based on fully biodegradable surfactant compounds, developed especially for use on class A fires. STHAMEX® -class A Classic is designed in particular for extinguishing ember forming solid material fires in combination with CAFS. The proportioning rate for extinguishing liquid fires (fire class B) is 1%.
