To mount undermount sinks, Tenax USA of Charlotte, NC, suggests Rivo Epoxy Glue. This product was forumulated to be easy to use (1:1 ratio), fast (15-minute gel time), strong (pure epoxy) and very inexpensive (same cost per liter as the polyester glue). For rodding, Tenax recommends either a flowing transparent glue, or if needed, Kotor System, a strong epoxy that is also suitable for materials that have not completely dried.
