Abesco Fire CP310 FR Acrylic Intumescent Caulk is designed to prevent the spread of fire from one compartment to another wherever services penetrate separating walls and floors, or wherever a gap remains between elements in fire rated walls or floors.
Abesco Fire CP310 FR Acrylic Intumescent Caulk is a single part water based acrylic caulk, which provides a firm but flexible seal to joints in a variety of fire rated structures. It will not support combustion, and when exposed to fire it forms a carbonaceous char which expands to effectively seal any gaps, and prevents the spread of smoke and fire.
Our Firestop CP310 FR Acrylic Intumescent Caulk is supplied in a range of packaging sizes.
