SEALANT 641 – 290 ml – Versatile sealant for clean rooms and air duct systems

SEALANT 641 is a high-performance MS-hybrid-based sealant that combines bonding and sealing in a single step. Its clear advantage: the product contains no silicone or solvents. At the same time, it withstands powder coatings up to +200 °C. This makes it ideal for demanding applications. Professionals use it for sealing air duct systems and technical installations.

In practice, sealants often have to meet several requirements: permanent adhesion, ease of application and, in addition, suitability for subsequent processes such as powder coating. Many products reach their limits here.
