Arbokol 2150
Description

A two part polysulphide sealant suitable for structural floor joints. It is not recommended for joints subject to large and frequent movement or for use with potable water.

The sealant is resistant to most alkalis and dilute acids, petrol, diesel, jet fuel and many solvents and vegetable oils. Arbokol 2150 burns, but will not readily ignite, so does not constitute a fire hazard.It 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. When used in trafficked areas, or in special environments such as swimming pools, the life may be reduced.
