Closed Cell Polyethylene Joint Sealant Backer Rod
NEO BACKROD supplied in circular cord lengths for use as a back-up material for sealing applications. It is resistant to weathering, ageing, inorganic salts, acids, ozone and animal and vegetable oils.
- NEO BACKROD are available for a range of applications in the industrial and residential markets. It has excellent stretching capabilities while remaining strong enough to be elastic.
- Provides bond breaker and minimum strain shape for joint sealant
- Provides a firm backing for sealant tooling
- Excellent water resistance and Ozone resistance
- Excellent chemical resistance (Acid and Alkali)
Application
NEO-BACKROD used in construction expansion joints to achieve the correct joint-dimen-sions and to prevent three sides adhesion of the sealant. Because of the closed cells NEO-BACKROD will give more support to the sealant and is most suitable for joints that are exposed to mechanical or water pressure.
Make sure that the width of the joint corresponds to the movement capability of the Sealant applied. The diameter of the Backer Rod is recommended to be approximately 20% higher than the width of the joint. It should be positioned so that the required minimum sealant depth can be obtained. The circular section of the backer rod provides a convex face giving a minimum strain shape for elastomeric sealants while reducing the stress at the bond interface.
