PU Sealant is a single component low modulus polyurethane sealant. It is for use in sealing joints in pre-cast elements, external walling and many cladding applications. Polyurethane offers excellent tear and abrasion resistance, fast curing properties, good shock and vibration resistance, high dynamic stress absorption and high movement capabilities.
One part, reduces the possibility of applicator error and possible joint failure
Excellent thixotropy - non-sag
Elastic low modulus
Pitch-free - over paintable
Movement capability +/- 25%
Bubble-free curing, no weak areas for air bubbles to develop
Excellent resistance to weathering (DIN 14231)
Very good adhesion to most construction materials especially concrete without the need of primer
Permanently elastic over a wide range of temperatures.
