Abstract
It has been unexpectedly found that the solvent extracted aromatic cut of heavy vacuum gas oil can be oxidized to produce an adhesive composition that has all the needed attributes of a self seal adhesive for asphalt roofing shingles. This self seal adhesive composition offers numerous benefits and advantages over conventional self seal adhesives for roofing applications. For instance, it does not require any volatile organic solvents and is accordingly environmentally friendly. Additionally, it does not contain any asphalt or polymers and will not phase separate and accordingly offers excellent long term stability.
