Drying of water-based sealing compounds
Importance of low residual moisture in the dry sealant filmBefore the seaming operation, the residual moisture of the lined compound shall be low enough.
As a general rule, longer dwell times and higher temperatures assure less residual moisture and better adhesion and resistance of the dry film.
In the case of inadequate drying in the oven, the evaporation of the remaining water may take several days, depending on storage conditions of the ends.
