Master Bond Super Gel 9 is a two component, urethane modified epoxy system that cures readily at room temperature to form a soft, resilient, gel-like system with good dimensional stability. Its hardness is exceptionally low, about 5-10 Shore A. One can accomplish retrievability with a sharp knife or razor blade and the Super Gel 9 will not shatter. It has a very convenient two to one mix ratio by weight or volume, along with an extremely low viscosity and exotherm enabling it to be cast in larger sections up to 2-3 inches thick.
