METHOD OF FORMING BITUMINOUS ROOF MEMBRANES |
摘要 |
<p>Roofing membranes are provided with both high stiffness at high temperature (greater than 110 ° C.) and good flexibility at low temperature (less than -20 ° C.). Bituminous compositions may be more effectively used in such membranes at lower elastomer concentration than currently practiced, using conventional cross-linking reagents to prepare the modified bituminous compositions with a range of viscosities that are readily processed as compared with conventional non-cross-linked systems.</p> |
