Product Description
The system is
comprised of a pre-compressed, silicone-and-foam hybrid installed into
field-applied epoxy adhesive on the joint faces; with the silicone bellows
locked to the joint faces with a silicone sealant band. The BEJS SYSTEM
features an innovation in sealant technology in the form of a
microsphere-modified, 100% acrylic impregnation infused into the cellular foam
base material. The material is odorless, clean handling, UV stable,
non-staining, and features low temperature flexibility not previously available
in asphalt, wax, or isobutylene-based predecessors or competitors. The result
is it can be used in applications where asphalt and wax-based predecessors did
not work well under conditions of thermal shock (rapid opening and closing of
joints during large temperature swings). Suitability is further extended to
applications in colder geographical regions to which asphalt and wax-based
predecessors have not previously been recommended.
