Features Of Wacker GENIOSIL STP-E30 SMP Adhesive

  1. One-component, moisture-curing silyl-modified polymer (SMP) adhesive with no isocyanates or solvents.

  2. Excellent adhesion to diverse substrates including metals, glass, ceramics, and most plastics without priming.

  3. High elasticity and permanent flexibility after curing, maintaining performance across wide temperature ranges (–40 °C to +90 °C).

  4. Low modulus and high elongation at break (>400 %), ideal for joints subject to dynamic stress and thermal movement.

  5. Good UV resistance and weathering stability, suitable for long-term outdoor applications.

Typical Applications Of Wacker GENIOSIL STP-E30 SMP Adhesive

  1. Structural bonding and sealing in transportation: bus, rail vehicle, and trailer body assembly.

  2. Modular construction and prefabricated façade systems requiring durable, flexible joint sealing.

  3. Bonding of insulated panels (sandwich panels) in cold storage and cleanroom facilities.

  4. Assembly of aluminum composite panels (ACP), fiber cement boards, and metal cladding systems.

  5. General industrial bonding where high green strength, paintability, and VOC compliance are required.
