Product Overview

Bostik Intucrylic is a high quality water-borne acrylic intumescent building sealant. In the event of a fire, it will swell (intumesce) to form an insulating char, which is fire resistant and will resist the passage of smoke and flame. It is used for sealing expansion, contraction and construction joints where compartmentation and movement are factors; as a bedding/sealing compound for locating fire resistant board systems; to seal gaps which occur between fire-rated building components and the surrounding structures i.e. window and door frames; and as a service penetration seal system for both cables and pipes.

  • Assessed to BS476: Part 20: 1987 to give up to 4 hours fire resistance in suitable structures
  • Swells to form a barrier in high temperatures
  • Joint movement accommodation of ± 12.5%
  • Will not slump in joints up to 30mm wide
  • Excellent adhesion to a wide range of substrates
