Abstract
The present teachings generally relate to a sealant composition that is adapted to be foamed, cured or some combination thereof, a method of making the activatable sealant composition and methods of using the same. The activatable sealant composition comprises one or more preferably high softening point or high melting point polymeric materials; one or more foaming agents; one or more foaming agent activators; and one or more hydrocarbon resins; wherein the activatable sealant composition is supplied to an article of manufacture for providing functional attributes such as scaling, baffling, dampening, reinforcement, or a combination thereof.
