Description

Powercrete® R-95 is a high-build solvent free novolac epoxy coating designed for protecting new line pipes and pipeline rehabilitation projects that operates at temperatures up to 95˚C (203˚F). Powercrete® R-95 can be used for extra protection on top of FBE mainline coatings or as a DTM (drirect to metal) coating when an increased temperature-and chemical resistance is required.
 

Features

  • 100% Solids Novolac Epoxy
  • no VOC
  • high temperature and chemical resistance
  • Excellent adhesion to FBE and abrasive blasted steel
  • Excellent cathodic disbondment characteristics
  • Excellent wastewater and sulphuric acid resistance
  • Suitable for pipeline operating temperatures to 95°C (203°F)
  • Can be sprayed and hand applied up to 1000micron (40mils) in one multi-pass layer
