Abstract
A water release agent that release water over an application temperature range in an amount sufficient to cure a composition is add to a curable composition containing 10 to 65 weight % of a moisture-curable, silane-functional, elastomeric, organic polymer; 0.1 to 3 weight % of a condensation catalyst; and (C) 15 to 25 weight % of a physical drying agent. When used as an edge-seal in an IG unit, the cured product of the composition performs the functions of sealing, bonding, spacing, and desiccating.
