Arbokol AG 2


A two part polysulphide sealant, suitable for perimeter joints where high movements are expected. Arbokol AG2 features:

  • Not recommended for very heavily trafficked areas.
  • Resistant to most alkalis and dilute acids, petrol, diesel, jet fuel, and many solvents and vegetable oils.
  • Very good UV resistance.
  • Burns, but will not readily ignite, so does not constitute a fire hazard.
  • Can be painted, but excessive joint movement may cause the paint to crack and could induce tears in the sealant.

Correctly applied, the sealant should not require maintenance, and has an anticipated life in excess of 20 years.
