OTTOSEAL® M 366 – Hybrid sealant for building construction joints, facades and connection joints

OTTOSEAL® M 366 is a high-quality one-part hybrid polymer STP sealant developed specifically for professional sealing work in building construction. The versatile sealant is excellently suited to expansion, connection and facade joints as well as permanently airtight internal seals and driving-rain-proof external seals. Thanks to its excellent weather resistance and high elasticity, OTTOSEAL® M 366 ensures durable, robust, reliable joints indoors and outdoors.

The silicone-free, isocyanate-free hybrid sealant adheres reliably to numerous building materials and is ideal for connection joints between windows and building structures, doors, gates, drywall walls as well as concrete, wood and glass components. In addition, OTTOSEAL® M 366 is the perfect solution for sealing facade joints and for closing cracks and holes in facades and internal walls.

Thanks to its paintable and coatable surface, the sealant can be optimally matched to existing surfaces. The low-odour formulation ensures pleasant application, while the tack-free surface after a short time reduces the risk of soiling. With its high ageing resistance and temperature resistance, OTTOSEAL® M 366 is the ideal choice for durable structural seals.
