A new product: Professional all-season PU foam sealant DONEWELL® 70.
The product is designed for installing windows and glazed units, as well as for a wide range of professional sealing, thermal and acoustic insulation work in construction.
Additives developed specifically for DONEWELL® foam balance the closed and open cells in the foam structure, which gives high deformation stability and an effective combination of thermal and acoustic insulation properties.
Low post-expansion is a feature of the whole DONEWELL® foam range: it keeps foam consumption under control
when filling joints. Fully cured DONEWELL® foam has a highly water-repellent skin, which considerably reduces the effect of air humidity on the installation joint and so extends its service life.
