Intumescent sealants are used to meet important fire safety standards and building codes. When exposed to fire, the intumescent sealant expands in volume to fill all cavities; providing a necessary fire-resistant seal.

This chemical reaction may stop or slow the spread of fire and provide critical escape time should a fire start.
