Application

Suitable for use in structural joints in heavy cladding, structural movement joints in floors, and floor joints in heavily trafficked areas. Prisons and secure units (supervised areas) forming anti-pick/anti-vandalism joints, or any area that could be subject to abuse and vandal attack.

Description

A one part, high modulus, modified polymer sealant which cures, on exposure to moisture vapour, to form a tough but elastic rubber.


Features and benefits:

  • Not recommended for joints in lightweight cladding and swimming pools.
  • Very good UV resistance.
  • Anticipated service life in excess of 20 years.

Chemical resistance

Resistant to most dilute acids and alkalis.

Guidance for specification option:

  • Organic solvents may cause the sealant to swell and loose adhesion.
  • Strong cleaning agents can cause surface deterioration and may affect the efficiency of the material.
