These are products designed mainly for professional use. Except their sealing function, they can be defined as elastic adhesives as well (for example for bonding solar panels on caravan roofs). Their most often use is for filling up joints in polished concrete, so as all kinds of technical joints in concrete. The other basic scope of use is determined by their very good adhesion to metal – when processing joints of metal products in carriage building industry, container building, shipbuilding, automotives and others.
