More than just extremely resistant
Like water off a duck's back. Specially developed for drainage systems, this product has excellent forming properties and is extremely resistant to scratching and corrosion (RC 4).
- Very good forming properties
- Additional resistance to scratching (35 N)
- Additional corrosion protection (RC4)
Highest UV resistance class (RUV 4)
Guaranteed up to 2100 meters above sea level
Highest performance in corrosion resistance thanks to higher layer thickness
This product features increased corrosion protection and can also be used for drainage applications in environments that contain high levels of salt or are heavily polluted by industrial emissions (RC 4). Furthermore, thanks to the higher layer thickness, the protection against mechanical damage is increased to 35 N.
