K-FLEX FIRE ACRYLIC

K-FLEX FIRE ACRYLIC is an one part acrylic sealant designed to prevent the spread of fire and smoke through joints and openings in fire rated walls and floors including openings formed around building service penetrations. K-FLEX FIRE ACRYLIC will also maintain the acoustic design performance in walls and floors. K-FLEX FIRE ACRYLIC cures when it is subjected to atmospheric conditions and retain a certain elasticity for joint movement. Under fire exposure, K-FLEX FIRE ACRYLIC creates a robust fire seal creating a durable intumescent char. Thermal activation takes place at about 180°C when the material will expand (intumesce) and prevent the passage of fire and smoke for periods up to and beyond 4 hours.

APPLICATIONS
- Construction joints in fire separating walls and floors;
- Acoustic seals around perimeters of fire resistant partitions;
- Gaps behind fire resistant door casings;
- Seating of fire resistant grills, intumescent pipe closer around pipes.
