Detailed product description
OTTOSEAL® S 140 is based on a high-quality, neutral-curing silicone with very good viscosity for precise application. It is temperature-resistant, UV-stable and developed specifically for areas where conventional silicones quickly reach their limits. Thanks to its fungicidal treatment it is ideally suited to professional applications in construction, the trades, sanitary areas and commercial wellness facilities.
For optimum results the joints should be clean, dry and free of release agents. Application takes place at moderate temperatures; the material is easy to smooth and cures evenly.
