MET-L-CHEK D-702 High Temperature Developer - 1 Pint (0.473 Liters)

The MET-L-CHEK D-702 is a specialized, high-temperature developer (Form “f” special application material) designed to work in conjunction with high-temperature visible penetrants, such as MET-L-CHEK VP-302. This developer is crucial in Liquid Penetrant Inspection (LPI) for drawing penetrant out of surface-breaking discontinuities and creating a clear, high-contrast white background for easy defect visibility on hot surfaces.

This 1-pint (approximately 0.473 Liter) container is suitable for precise application in field inspections, testing, or small-scale industrial use where components are at elevated temperatures.

Key Features & Benefits:

• High Temperature Performance: Specifically formulated for use on surfaces with elevated temperatures, compatible with the range of 51.6∘C to 176.6∘C (125∘F to 350∘F). This allows for immediate inspection of hot components without the need for cooling.

• Form “f” Special Application: Classified as a special application developer under AMS-2644, indicating its unique properties for high-temperature use.

• Enhances Indication Visibility: Dries quickly to form a thin, uniform, opaque white coating that provides excellent contrast for visible red penetrant indications.

• Fast Drying: Allows for rapid inspection turnaround, improving efficiency in demanding environments.

• Low in Halogens & Sulfur: Contains very low levels of Sulfur, Chlorine, Fluorine, and other halogens, ensuring its safety for use on sensitive alloys like titanium, nickel-based alloys, and stainless steel found in nuclear and aerospace applications.

• Easy Removability: The dry film is easily removed with water after inspection, simplifying post-inspection cleanup.

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

  • AMS-2644 (Form “f” Special Application)

  • 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 reputable supplier of NDT consumables, ensuring consistent quality and performance.
