DESCRIPCIÓN
DESCRIPTION
 
Tremco backer rod is an extruded round, closed- cell, low density polyethylene foam material with a skin-like outer texture. It is highly flexible and an ideal non-absorbent compressible backup material. It is compatible with butyl, polysulfide, acrylic polyurethane, silicone and most other cold applied sealant compositions.
 
BASIC USES
 
It is inserted into a joint to control sealant depth to create a backstop to:
Allow proper sealant tooling.
Allow proper sealant wetting of the joint
surfaces.
To yield a proper bond breaker between the
backer rod and sealant.
 
It can also be used as a temporary seal. Commonly used in glazing installations, window and door applications, expansion joints, curtain wall joints, partitions, log construction, pavement joints, repairs, precast units and copings.
