Met-L-Chek D-702 is a specialized, high-temperature, non-aqueous developer formulated to enhance the detection of surface cracks and porosity on hot surfaces when used in conjunction with Met-L-Chek® high-temperature penetrants like VP-302. This developer is supplied in a convenient 5-gallon pail, offering an economical solution for high-volume applications.

Specifically designed for use on components with surface temperatures ranging from 125°F to 350°F (51.6°C to 176.6°C), D-702 significantly reduces inspection process time by eliminating the need for complete cooling of parts before inspection. This makes it ideal for in-field welding inspections, weld repair assessments, and the examination of refinery processing equipment operating at elevated temperatures.

D-702 dries rapidly to form a thin, white film that provides a high-contrast background for penetrant indications, making even fine discontinuities easily visible. After inspection, the developer film is easily removed with water, simplifying the post-inspection cleaning process.  

This product is low in sulfur, chlorine, fluorine, and other halogens, making it safe for use on titanium and high-nickel alloys commonly found in critical components, including those used in nuclear applications.  

Key Selling Points:

• High-Temperature Application: Specifically formulated for use on surfaces up to 350°F (176.6°C), eliminating cool-down time.  

• Enhanced Indication Detection: Creates a thin, white film for high-contrast visibility of surface flaws.  

• Water-Removable: Simplifies post-inspection cleaning.  

• Safe for Critical Alloys: Low in sulfur and halogens, safe for use on titanium and high-nickel alloys.  

• Economical 5 Gallon Pail: Ideal for high-volume users, offering a cost-effective solution.

Benefits:

• Increased Inspection Efficiency: Eliminates the time-consuming cool-down process for hot parts.  

• Improved Flaw Visibility: High-contrast developer ensures easy identification of surface defects.

• Versatile Applications: Suitable for field welding, repair inspections, and hot operating equipment.  

• Safe for a Wide Range of Materials: Can be used on various alloys without risk of corrosion or degradation.  

• Cost-Effective for Large-Scale Use: The 5-gallon pail provides a lower per-gallon cost for frequent users.

Applications:

• Inspection of welds immediately after welding.

• Examination of hot components during repair processes.

• In-service inspection of refinery processing equipment.

• Quality control on pre-heated parts prior to welding.

• Any application requiring penetrant inspection on surfaces with elevated temperatures.
