Steep Type III Asphalt minimum the softening points to minimize the risk of slippage and reduce fallback. With the use of high flashpoint raw materials it provide additional safety. It also widen the spread between equiviscous temperature and flashpoint to support application, adhesion and waterproofing.

Features:

• Consistent high flash material
• 19 producing plants
• Printed cartons
• EVT shown on each carton and bill of lading for bulk shipments
• Testing in each plant and at Summit, IL laboratory

Benefits:

• Each shipment meets or exceeds the physical requirements of the specified roofing grade asphalt
• Proper temperature range needed to apply product safely at the EVT; flash points typically 50°F to 75°F higher than the 500°F minimum
• Convenient, accessible availability from coast to coast
• Assures proper adhesion, waterproofing and application rate
• All Owens Corning Trumbull products are assured to meet ASTM requirements
• Clearly identifies manufacturers, type, flash point, EVT, production location and production date
