Conventional joint systems for expansion joints on industrial floors are based on polyurethanes, silicones, MS polymers or polysulphides. These are usually less resistant than the adjoining coating and vulnerable to chemical attack, quickly becoming brittle and needing to be repaired within relatively short intervals. Mycoflex Resyst can eliminate this vulnerability. MC-Bauchemie’s product system consists of prefabricated mouldings made from a special polymer foam that is highly resistant to chemical attack, mechanical stressing and permanent water exposure. It delivers a thoroughly reliable joint system for floors and expansion joints, even where components suffer significant thermal expansion and heavy mechanical wear and tear. This makes the joint system particularly suited to a wide range of industrial floor applications, especially the chemical and oil industries and in the sewage treatment sector.
