PETRONAS Launches New Graphene-Based Corrosion Protection Technology
Malaysian oil and gas company Petroliam Nasional Berhad (Petronas) has launched a new paint additive formulated with graphene to protect steel structures against corrosion ProShield+ can reportedly double the average lifespan of surface coating to last up to 16 years.
Developed in-house by Petronas, the additive has reportedly been proven to strengthen coatings’ resistance against harsh weather conditions and protect assets from corroding agents. According to the release, ProShield+ has been piloted and deployed at specific Petronas upstream and downstream assets.  The company reports that the formulation contains overall three times higher water barrier properties than conventional epoxy paint and helps to improve adhesion as well as resistance against abrasion and ultraviolet (UV). It has also shown up to three times more improvement in abrasion resistance than conventional epoxy paint. It can be added to major paint systems without requiring any change to the existing blending process, applied the same way as other coats of paint.

Critical Questions for Protective Coatings for Asset Protection in Oil & Gas, LNG:

  • Why is the coating not stopping corrosion?
  • Why is the coating delaminating or blistering?
  • Has the coating been correctly specified / applied?
  • Does the coating meet the manufacturing standard, including properties such as correct hardness/cure, adhesion and thickness?
  • What surface preparation and atmospheric conditions must be achieved to successfully apply the coating?
  • Does the coating have any defects in it? How will these affect performance?
  • Why did the coating fail? Root cause assessment.
  • How can the coating be successfully repaired/remediated so that it doesn’t fail again?

ExcelPlas Labs provides independent testing, analysis, and investigation on protective coatings to prevent corrosion.

ExcelPlas has extensive analytical capabilities for testing of Protective Coatings and Insulation Consulting for major oil and gas companies.

We conduct corrosion surveys, coating sampling, coating analysis, and testing to ensure coating specifications for a wide range of onshore and offshore clients in Australia and the Asia-Pacific Region.

ExcelPlas Labs offer a full range of coating testing and analytical services to Australia’s mining, oil, gas, and infrastructure sectors.

Forensic analysis for undertaking various coating-based failure investigations and problem-solving.

ExcelPlas Undertakes Analysis & Testing of Polymer Coating Systems including:

  • Epoxy Protective Coatings
  • Epoxy-Phenolic Protective Coatings
  • Fusion bonded epoxy (FBE) 
  • Dual-Layer Fusion bonded epoxy (DLFBE)
  • Liquid applied epoxy (LAE)
  • Abrasion-resistant overcoat (ARO)
  • Three-layer PE (3LPE)
  • Multi-component liquid spray  (MCL)
