In an airport emergency every second counts. That's why airports count on the best equipment available. Fire engines which meet ICAO standard achieve high acceleration values rates and carry tons of fire extinguishing agent. The fire extinguishing foam used must also meet special performance criteria on kerosene and aviation fuel. With vaPUREx® LV ICAO C 3%, Dr Sthamer is setting new standards
Forest and vegetation fires are becoming increasingly frequent and intense. They pose a major risk to people and wildlife, but also to forests as an economic factor and, in particular, as storage sites for CO2. […]
In many fire situations—especially vegetation and wildfires—the availability of extinguishing water presents a logistical challenge. This makes it all the more important to use available resources as efficiently as possible. One effective method for optimizing water consumption is the use of wetting agents. What are wetting agents? Wetting agents, such as the high-performance wetting agent "UltraWet®" from Dr. STHAMER, are special additives that […]
Viscosity is a measure of the thickness or internal friction of a liquid. It describes how much a liquid resists deformation or flow. Simply put: the higher the viscosity, the “thicker” the liquid – and the lower the viscosity, the more “fluid” or “runny” it is. Most fluorine-free foam extinguishing agents are low-viscose, meaning they have a thin, water-like consistency and can be easily proportioned. […]
An unusual action is causing a stir in North Rhine-Westphalia: In the forests of Affeln in the Sauerland region, a flame retardant in a striking pink color was sprayed on approximately 200 square meters of forest floor. This measure has a serious background and is not the only such project.
Forest and vegetation fires are becoming increasingly frequent and intense. They pose a major risk to humans and animals, but also to forests as an economic factor and, in particular, as storage sites for CO2.
On Saturday, March 22, 2025, a flame-retardant was tested for the first time in North Rhine-Westphalia on approximately 200 m² of forest land in the town of Neuenrade in Affeln. The test of the fire retardant was conducted at the initiative of @fire and in cooperation with Forest and Wood NRW, the Lower Nature Conservation and Water Authorities of the Märkischer Kreis, the town of Neuenrade, and the Neuenrade Fire Department.

Wetting agents such as UltraWet® or low-dosed foam concentrates like STHAMEX®-Performance reduce the surface tension of water. This allows the water to adhere better to solid surfaces and penetrate more deeply into porous or hydrophobic (water-repellent) materials. This phenomenon is known as the wetting effect. In firefighting, the wetting effect means that water – when combined with a wetting agent – no longer beads […]
