Met-L-Chek® D-702 is a special application high temperature inspection developer, form “f”, used with Met-L-Chek® VP-302 to enhance detection of surface cracks and porosity on hot surfaces. Met-L-Chek® D-702 dries quickly and produces a thin white film, which is easily removed with water after inspection.

Commonly used in field welding and welding repair inspection, D-702 is also used in the inspection of refinery processing equipment at elevated temperatures. Met-L-Chek® D-702 reduces inspection process time by eliminating the total cool down period required for standard penetrant.

APPLICATIONS

• Surface crack detection
• Porosity of hot surface detection
• See full list of approvals below

FEATURES

• Use range of 51.6 ?C – 176.6 ?C (125?F -350?F)
• Low in sulfur, chlorine, fluorine and other halogens
• Safe on titanium and high nickel alloys found in nuclear components
• Reduces inspection process time by eliminating the total cool down period required
