CP310 FR Acrylic Intumescent Caulk

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.
