A new generation of ecological PU coatings with water vapour permeability
Today, nearly all “breathable” PU direct coatings are applied from solvent systems. These products partly contain very harmful and environmentally hazardous solvents. RUCO®-COAT ECC NEW is purely water-based and thus, opens up new perspectives for numerous coated fabrics, which are permeable to water vapour and thus, “breathable”.
The hydrophilic segments incorporated in RUCO®-COAT ECC NEW and ECT ensure excellent water vapour permeability. Once sweating, a higher humidity in the jacket , thus, a higher water vapour concentration arises. These differences in concentration ensure that water molecules are transported along the polymer chain to the outside due to the hydrophilic segments incorporated.
The higher the difference in concentration, the better the function of this principle. But if it is cold and you don’t sweat, less heat gets lost. This is important for clothes (sportswear, outdoor, shoes etc.), but also for technical textiles (tents, sleeping bags, etc.).
