Urethanized Bitumen System for Waterproofing Roof

Home » Technology » New Technologies » Building and Construction » Urethanized Bitumen System for Waterproofing Roof



Sealing, coating, adhesives and foam


Salient Features


Urethanized bitumen has been prepared with variable viscosity, adequate elastic resiliency and a reduced thermal susceptibility. These behaviour are confirmed by the thermal (DSC), rheological and IS: 1208-78. Its waterproofing functions is further assessed by IS: 1580 and IS: 1834-84 & ASTM D-3409-95 respectively. After assessing the materials suitability, compositional variables in products and parameters related to blend preparation are optimized. The urethane bituminous system has been prepared as per the requirement of end use applications.
