SOPRASPHALTE™ M is an SEBS-modified asphalt used to adhere SBS-modified bitumen membranes. SOPRASPHALTE M is specially formulated to have high tensile strength, high recoverable elongation, cold temperature flexibility, good flow resistance and greater thermal stability when compared to conventional roofing asphalt.
SOPRASPHALTE M must be heated to a minimum of 428°F prior to being applied. SOPRASPHLATE M must not be heated to temperatures above 500°F to avoid deterioration. When proper temperature can be achieved, SOPRASPHALTE M is applied via mop to the substrate.
