DURArods (formerly SILSEAL)
‘DURArods’ is a closed cell polymer based product with a circular profile. It ensures stronger bonding of sealant with masonry,aluminium or other substrates & helps to maintain desired thickness of sealant at the joints center.It does not bond with cold applied sealants.It is used as a back-up to sealants in expansion joints and structural glazing systems.

1) Feature & Benefits

Closed cell, hence negligible water/moisture absorption
Excellent chemical resistance-inert to most acids and alkalis
Cost effective space filer
Allows unrestrained expansion & contraction of sealants. Eliminates bubbling of sealant.
Non-staining-Reduces sealant consumption.
