  • General-purpose applications
  • Suitable for flaw detection and thickness gauging
  • Now available in bright, vibrant colors that won't fade or turn cloudy

UT-X Powder

Cost-effective couplant powder for flaw detection and thickness gaging applications with ferrous corrosion inhibition. UT-X Powder retains viscosity on salt caked boiler tubes, corroded pipe, structural steel, steel billets, welds and ship plate.

Key Features:

  • Powder form for cost-effective mixing
  • Excellent for heavily corroded surfaces
  • Ferrous corrosion inhibition properties
  • Retains viscosity on challenging surfaces
  • Ideal for industrial applications with severe corrosion
