Application Instructions

All surfaces must be clean and dry and free from dirt, dust, grease and other contamination. Light abrasion of
the surfaces to be bonded will improve the adhesion.
Apply the adhesive from the cartridge, forcing it onto the area to be sealed, then immediately tool it down to
ensure good adhesion. Complete tooling within 5-10 minutes.
When bonding materials, apply a bead of adhesive to one surface and immediately combine the two parts,
applying pressure to ensure good surface contact.
Application equipment should be cleaned with warm water after use.
It is necessary to fully dry the product before subjecting to temperatures above 100oC to prevent gassing and
likely failure of the seal/bond. Allow to air dry for 36-48 hours, after which gentle heat can be gradually
The dried product can be removed with boiling water.
