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. […]

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 […]

A wildfire is a devastating natural phenomenon that annually destroys vast areas of forest and poses a threat to humans and animals. The impacts of wildfires are not limited to the affected ecosystems but also have far-reaching consequences for the climate and air quality. Moreover, they pose a significant economic risk to forestry and forest management. […]
