Description

Useal 7702 is a one-part, non-slump, moisture-curing RTV (room temperature vulcanizing) that cures to form a tough, high modulus rubber with long-term flexibility and durability. The neutral curing mechanism is ideally suited for use in confined work areas since no objectionable odors are evolved. The non-slump characteristics allow application to vertical or horizontal joints without flowing or sagging.
