Application

For sealing minor gaps and imperfections local to AIM cavity and fire barrier products and for use as a general purpose fire rated sealant in voids up to 35 mm between a range of substrates.

Description

AIM Intumescent sealant is a halogen free, polymer emulsion-based sealant that swells when subjected to temperatures in excess of 125°C and forms a char coat that restricts the passage of smoke and fire.


It is easily applied and dries to a flexible and smooth surfaced material which is readily over paintable. It also has good adhesion to a wide range of substrates and will not harden or crack with age.


Features and benefits:

  • Supplied in 310 ml cartridges.
  • Tested with AIM’s cavity and fire barrier range.
  • Seals voids of up to 10 mm between the barrier and the substrate.
  • Tested to provide 120 minutes fire integrity adjacent to AIM cavity and fire barriers and 240 minutes as a general purpose sealant.
  • Cure rate of 5 to 15 days dependent upon bead size, substrate, and drying conditions.
  • Skinning time of 15 minutes to an hour depending on conditions.
