TEKAFLEX PU 40
TEKAFLEX PU 40 is an elastic, adhesive and sealant based on polyurethane
Base. Excellent adhesion to many common building surfaces
Materials such as: metals, concrete, brick, wood, aluminum, iron,
Stainless steel, copper and various types of plastic. High strength
and very good mechanical properties.
Application
TEKAFLEX PU 40 is suitable due to its material composition
and the resulting properties especially for
gluing and sealing various materials.
For the realization of elastic connections and expansion joints
between different materials inside and outside
facades and on the ground. For bonding window frames,
lighter building materials, roof coverings and floor panels.
For sealing joints in vacuum systems, compressed air networks,
Containers, containers, silos, aluminum structures and sewerage systems.
