For joints in trafficked areas like in roads, parking areas and airports, especially in cases of renovation work, the ability to get back to full traffic access within a few hours is a key requirement. Therefore, fast curing systems are very important nowadays with the increasing traffic in cities and airports, where there is often only a slot of a couple of hours, for example during night, when the airport is closed. For such applications, either 2-component products can be used or 1-component products with a so-called booster, which is a kind of accelerator. This system combines the advantages of both one- and two-component joint sealing systems with the benefit of having a long pot life together with very fast curing to provide a system which is not sensitive to any mixing failures because it will also cure like a 1-component sealant. This so-called booster technology is already frequently used in industrial application but is quite new in the construction industry. This booster technology can be used basically for polyurethane, silicones and silane terminated polymers which are usually used as one-part moisture curing products.
