Backer Rod - Polyurethane Foam ProductsClosed Cell Polyethylene Foam.

PRODUCT DESCRIPTION

Lightlon Backer rod is an ideal non-absorbing compressible backup material. It is inserted into a joint to control sealant depth to create a backstop to:

  • Allow proper sealant curing
  • Allow proper sealant wetting of the joint surfaces
  • Insulate underside of sealant
  • Yield a proper bond breaker between the backer rod and sealant

It can also be used as a temporary joint seal.

COMPATIBILITY

Lightlon Backer rod is compatible with butyl, polysulfide, acrylic, polyurethane, silicone and most other cold applied sealant compositions.

SPECIFIC USES

Commonly used in glazing installations, window and door applications, expansion joints, curtain wall joints, partitions, log construction, pavement joints, repairs, pre-cast units and copings.

COMPOSITION AND MATERIALS

Lightlon Backer rod is an extruded round, closed cell, low density Polyethylene Foam material with a skin like outer texture. It is highly flexible and compressible for easy installation. It is available in white. It is available in a wide variety of diameters.

TECHNICAL DATA

Lightlon® Backer Rod is chemically inert and will resist oil, petrol and most other solvents. This material will not stain nor adhere to sealant materials and is non –exuding.

INSTALLATION

The joint or opening must be clean, dry and free of obstructions. Select the proper rod diameter and cut to length or use directly from spool. With a blunt instrument or roller, uniformly install rod at the level recommended by the sealant manufacturer, specifier or architect involved. Generally, the depth of the joint after the backer rod is installed is one half the width. Very large and very small joints vary in terms of this depth to width ratio. Do not puncture or overly compress.
