85/25 & 115/15 for Built-up Roofing


BLOWN ASPHALT is produced by air blowing of petroleum residues. The grade of BLOWN ASPHALT is designated by two numbers, the softening point and the penetration degree.


  • In the construction of built up roofing as bonding or flood coats, 85/25 asphalt is used on inclines not exceeding 25% slope and 115/15 asphalt is used on inclines not exceeding 50%, and is preferred in high temperature areas due to its higher softening point.
  • For corrosion resistance for piping coating, steel structures, and in electric cable joint protection and industry.
  • As joint filling and sealant compound.
  • As an adhesive of building material.
  • For sound dampening felts and under carriage sealant in the automotive industry.
