ECO-VENT®: The new generation of ecological, water-vapour-permeable PU coatings

Today, virtually all breathable PU direct coatings are applied from solvent systems. These products partly contain very health-hazardous solvents which are harmful to the environment. RUCO-COAT EC PU dispersions are water-based and, thus, open up new perspectives for numerous water-vapour-permeable and thus breathable coated articles.

Coating properties

  • High water vapor permeability, depending on process and add-on, up to 20,000 g/m2/24 h
  • Breathable
  • Windproof
  • Good hydrostatic head
  • Halogen-free, NMP-free
  • Excellent film forming properties, closed film surface
  • Depending on add-on, soft coating
  • High resistance to hydrolysis
  • Recyclable
  • BE-FLEX® - Flexible handling: Flexible adjustment of degree of hardness
  • Combination with SILVERPLUS®

Function and fields of application

The incorporated hydrophilic segments in RUCO-COAT EC PU dispersions ensure excellent water vapour permeability. Sweating increases moisture in the jacket, i.e. the concentration of water vapour increases. These differences in concentration ensure that water molecules are transported to the outside by hydrophilic, incorporated segments along the polymer chain. The higher the difference in concentration, the better works this principle. However, if it is cold and there is hence no sweat, less warmth is lost. This is important for clothing (sportswear, outdoor, shoes, etc.) and for technical articles (medical applications, mattresses and mattress toppers, under tile breather membranes, etc.).

Fields of application

  • Protective clothing
  • Outdoor, ski jackets
  • Gloves
  • Military clothing
  • Medicine
  • Civilian uniforms
  • Shoes
  • Vapour barriers
  • Under tile breather membranes
  • Membrane production on suitable release paper or tows
