Abesco CP310 FR Acrylic Intumescent Mastic 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 constructions, walls or floors, and provides up to 4 hours fire resistance.

Abesco CP310 FR Acrylic Intumescent Mastic is a single part water based acrylic mastic, 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, preventing the spread of smoke and fire through any joints.
