In car production, elastic adhesives have become indispensable. Now these polymers are beginning to take over the construction industry. On walls and facades, floors and roofs, there are all kinds of items to be stuck and sealed.
All home improvement enthusiasts have used silicone at some time in their lives. Whenever joints have to be sealed in the bathroom or the kitchen, this viscous mass is a necessity; the paste is easy to apply and cures quickly at room temperature. But what about painting over the silicone seams or using the product to lay a new parquet floor in the living room? Preferably not. On such occasions, the professional will opt for polyurethane, which has better paint adhesion as a sealant and much better mechanical properties as an adhesive. Researchers from Bayer Polymers have now developed a range of adhesives and sealants that combine the advantages of polyurethanes with those of silicones, thereby minimizing their disadvantages at the same time: silane-terminated polyurethanes (STP).
