About This Product

Details

A watertight expansion joint, the DSM System is for horizontal-plane deck applications. Traffic durable, joint-face adhered and pre-compressed, DSM System is a primary seal for deck expansion joints. DSM’s toughness and resilience come from its microsphere-modified-acrylic impregnation and tensionless highway-grade silicone bellows coating.

The system is comprised of precompressed, silicone or Silyl Terminated Polyether (STPE) impregnated-foam hybrid installed into field-applied epoxy adhesive on the joint faces with the silicone bellows locked to the joint faces with a silicone or STPE sealant band.

The DSM System features an innovation in sealant technology in the form of an acrylic adhesive infused into the cellular foam base material. This new chemistry incorporates a hydrophobic microsphere component never before available in a sealant formulation.

The material features sealing performance significantly greater than any acrylic impregnated predecessor. In addition, it is odorless, clean handling, UV stable, non-staining, and features low temperature flexibility not previously available in asphalt, wax, or isobutylene-based predecessors.

The result is extension of the usability of the product to 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). These applications include joint-face adhered installations on top decks as well as intermediate decks.

Suitability is further extended to horizontal-plane joint applications in colder geographical regions to which asphalt and wax-based predecessors have not previously been recommended.
