Why PPG Hi-Temp™ 480?

Performance in high-temperature environments

 PPG Hi-Temp™ 480 is designed to deliver reliable protection in extreme conditions.

  • Withstands temperatures up to 250°C (480°F) with peak exposure up to 275°C (530ºF).
  • Proven resistance to thermal shock and cyclic conditions
  • Designed for use on carbon steel and stainless steel under insulation
  • Performs from cryogenic temperatures (-196°C/-320ºF) to elevated heat

Anticipated Result:

  • Reliable protection where coating failure leads to costly downtime.

Corrosion protection where it matters most

 PPG Hi-Temp™ 480 is engineered to help control CUI, one of the most challenging maintenance risks.

  • Meets ISO 19277 CUI-1, CUI-2, and CUI-3 standards
  • Meets requirements for NORSOK systems 1D / 6C and 9
  • Certified to ISO 12944-6 C5H for high-corrosion environments
  • Delivers strong anti-corrosion performance in aggressive service

Anticipated Result:

  • Longer asset life and fewer maintenance interventions.

Protect more assets with one trusted system.

Increase productivity across every project

Single-coat capability

 PPG Hi-Temp™ 480 helps reduce complexity compared to traditional multi-coat systems.

  • One coat at 250 μm (10 mils) with full performance
  • Two-coat option at 125 μm (5 mils) per coat
  • Designed to provide consistent performance across both application approaches

Anticipated Impact:

  • Faster turnaround
  • Reduced labor requirements
  • Simplified specifications

Surface tolerance for real conditions

Designed for flexibility in maintenance and new construction.

  • Compatible with St2 and St3 surface preparation*
  • Reduces reliance on intensive abrasive blasting
  • Well suited for maintenance and repair environments

*St2/St3: Steel cleaned using hand or power tools to remove loose rust and coatings (no abrasive blasting required).

Anticipated Impact:

  • Lower preparation costs and improved project timelines

Efficient application

PPG Hi-Temp™ 480 supports smoother, more efficient application processes.

  • Advanced formulation supports smooth application and film build
  • Designed to promote application efficiency across jobsite conditions
  • Can be applied on hot substrates up to 150°C (302°F)

Anticipated Impact:

  • Easier application with fewer disruptions in the field.

Support sustainability and compliance

Low VOC, high solids

Formulated to meet environmental and operational expectations.

  • VOC up to 175–200 g/L (≈1.5–1.7 lb/gal)
  • High solids content for efficient application 

Reduced operational impact

  • Fewer coats help reduce material usage
  • Shorter project timelines reduce energy demand and downtime

Anticipated Impact: Improved sustainability profile with no compromise in performance.

Certified for demanding environments

 PPG Hi-Temp™ 480 meets globally recognized standards:

  • ISO 12944-6 C5H
  • ISO 19277 CUI-1, CUI-2, CUI-3 including cryogenic service
  • NORSOK M-501 (2022) systems 1D, 6C, 9

What this means: Confidence in performance across harsh operating conditions.

Typical applications
