ANALYSIS OF ACCELERATED ORGANIC COATING MATERIALS USED IN CONJUNCTION WITH BURIED PIPELINE BY FTIR
Keywords:
3- Layer Polyethylene, Coal Tar Enamel & Coal Tar Epoxy.Abstract
Pipeline coating material such as coal tar enamel, coal tar tape, coal tar epoxy, high build epoxy, polyurethane, cold applied PE tapes and 3 layer polyethylene are prepared as tape / film and FTIR spectrum are recorded. These seven coating material are subjected to accelerated cathodic disbondment test as per ASTM B117 and ASTM G8 Standards. Further, FTIR spectrum are recorded for these disbondment portion of coating. Finally assessment are made about degradation of different resin systems.
