AIM Intumescent Acrylic Sealant
Verified by manufacturer 11 days ago
An acrylic intumescent sealant for sealing minor gaps and imperfections to cavity and fire barrier products. It may also be used as a general purpose fire rated sealant in a variety of applications.
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.
