AEROSANA® VISCONN
Sprayable Airtightness Sealant with a Humidity-Variable sd Value, Blue (wet)/Black (dry)
Advantages
- Sprayable airtightness sealant with a humidity-variable MVTR
- Can be plastered/painted over
- Suitable for application in indoor and protected outdoor areas, thanks to its humidity-variable MVTR
- Lowest VOC rating in hazardous substance test.
Areas of application
For use as a humidity-variable vapour control and airtight layer that can be applied as a spray or with a brush. It is suitable for wall, ceiling, and floor surface applications, such as non-plastered masonry or porous panel-form materials. AEROSANA® VISCONN can also be used for creating joints to components such as windows, roofs, walls, ceilings, and floors. Use on the interior and exterior of building structures due to the product's humidity-variable diffusion resistance. Once dried, the sprayed-on liquid film forms a seamless, elastic, airtight, and vapour-controlling protective layer. It sticks to all standard construction materials, pro clima membranes and membranes made from aluminium and paper. Sprays on blue, dries black.
