MET-L-CHEK VP-302 High Temperature Visible Penetrant - 5 Gallons (18.9 Liters)

The MET-L-CHEK VP-302 is a specialized high-temperature, visible (Type 2) penetrant used in Liquid Penetrant Inspection (LPI) or Dye Penetrant Testing (DPT). This red-colored, solvent-removable penetrant is formulated to detect surface-breaking discontinuities such as cracks, porosity, laps, and seams in a wide range of non-porous materials. Its key advantage lies in its ability to be applied to hot surfaces, eliminating the cool-down period typically required for conventional penetrants.

This 5-gallon (18.9 Liter) bulk container is ideal for industrial use, allowing for immersion, brush, or spray application methods in high-volume inspection environments.

Key Features & Benefits:

• High Temperature Performance: Specifically formulated for use on surfaces with elevated temperatures, ranging from 51.6∘C to 176.6∘C (125∘F to 350∘F). This feature drastically reduces inspection time by eliminating the need for parts to cool down.

• Visible Red Indication: Produces bright, vivid red indications against a white developer background, allowing for inspection under natural or white light without the need for UV-A (blacklight) illumination.

  
  

• Solvent Removable (Method C): Excess penetrant is removed from the surface using a solvent cleaner (such as MET-L-CHEK R-502 or R-503), providing flexibility and precise control over the removal process.

  
  

• High Sensitivity: Although visible penetrants are not rated by sensitivity levels per AMS-2644, VP-302 is considered approximately equal to Level 1 fluorescent penetrants, capable of detecting fine discontinuities.

• Low in Halogens & Sulfur: Contains very low levels of Sulfur, Chlorine, Fluorine, and other halogens, making it safe for use on sensitive alloys like titanium, nickel-based alloys, and stainless steel, commonly found in nuclear, aerospace, and high-temperature refinery components.

  
  

• Ease of Use: Can be applied by brushing, spraying, or dipping, offering flexibility in inspection procedures.

• Comprehensive Compliance: Fully qualified and meets the stringent requirements of numerous international and industry specifications, ensuring its suitability for critical applications:

  • AMS-2644 (Type 2, Method C)

  • ASME Boiler and Pressure Vessel Code, Section V

  • ASTM E-165 / ASTM E-165M

  • ASTM E-1417 (Standard Practice for Liquid Penetrant Testing)

  • ISO-3452-2

  • MIL-I-25135C (Interim AM-4)

    
    

  • NAVSEA-250-1500-1

• MET-L-CHEK Quality: Manufactured by MET-L-CHEK, a long-standing and reputable supplier of NDT consumables, ensuring consistent quality and performance.
