Aro-Seal® 1156 is a one component, high modulus, polyurethane sealant.
Aro-Seal® 1156 can be used for bonding and sealing a wide range of substrates in both structural and non-structural applications.
Aro-Seal® 1156 is suitable for use in sealing and bonding applications in the construction industries, flooring applications and structural bonding in vibrating constructions. Aro-Seal® 1156 complies to ISO 11600 Type F Class 25 Sub-class HM.
Ensure that the surfaces to be bonded are smooth, clean and free from dust or other deposits. Recommended application temperature is within the range of 5°C to 30°C.
Insert the cartridge or sachet into a suitable applicator, e.g. a skeleton gun, or pneumatic applicator. Slit the cap, or the end of the sachet, and screw on the nozzle. If required, slit the nozzle to increase the size of the orifice. Dispense the bead of adhesive on one side of the substrates to be bonded. Bring substrates together and apply pressure to ensure full contact.
For porous surfaces a suitable primer may be used to improve the cure, where preliminary adhesion tests indicate that it would be advisable. Likewise, where necessary, Aro-Seal® Surface Activator may be used on non-porous surfaces.
Clean tools with acetone or alcohol immediately after use. Cured material can only be removed mechanically.
Aro-Seal® 1156 should be stored in the original cartridges in a cool, dry place, at a temperature range of between 5°C and 25°C. In these conditions it has a storage life of at least 12 months in cartridges.
