FR ASF - Technical Data Sheet

Protecta® FR ASF is designed to prevent the spread of fire, smoke and gases through openings in fire rated walls and floors, specifically linear joints and openings for building service penetrations. Protecta® FR ASF should be applied over suitable backing materials to ensure correct width to depth ratio and to reduce shrinkage of the joint during hardening. In areas with a high degree of humidity and/or in joints with excessive movement, use Protecta® FR IPT. Protecta® FR ASF is a 2 hour rated intumescent sealant formulated with fillers that provide noise reduction. Protecta® FR ASF cures when it is subjected to atmospheric conditions, however it will retain a small degree of elasticity for joint movement.
