Features Of Wacker GENIOSIL STP-E15 SMP Adhesive

  1. One-component, moisture-curing silane-terminated polymer (STP) adhesive with no isocyanates or solvents.

  2. Excellent adhesion to a wide range of low-surface-energy substrates including plastics, metals, and coated surfaces—without primers.

  3. Outstanding elasticity and long-term durability under thermal cycling, UV exposure, and humidity.

  4. Low modulus formulation enables high movement capability (±35% joint movement) and stress relief in dynamic joints.

  5. Non-staining, neutral-cure chemistry suitable for sensitive architectural and interior applications.

Typical Applications Of Wacker GENIOSIL STP-E15 SMP Adhesive

  1. Structural bonding of façade elements (e.g., aluminum composite panels, fiber cement boards).

  2. Sealing and bonding in prefabricated concrete and steel building systems.

  3. Interior fit-out applications including ceiling systems, partition walls, and decorative cladding.

  4. Automotive and rail vehicle assembly for non-structural interior bonding and vibration-damping joints.

  5. Industrial equipment enclosures and control cabinet assembly requiring durable, flexible adhesion.
