Abstract
A method of controlling the flow of a heat activated expandable sealant is provided in which a heat activated sealant is coated with a flow control agent having a melt flow rate which is lower than that of the sealant. The combination sealant/flow control agent is preferably used to seal gaps or cavities in parts such as components in automotive vehicles with minimal sagging.
