Polyurethane Sealants, For Construction, Grade : Chemical Grade, Industrial Grade

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.
 
Benefits:

• 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.
