A bright white, non-aqueous developer, SKD-S2 creates an opaque white background for high-contrast penetrant testing and quickly draws penetrant out to create stronger, clearer indications for better inspection reliability and sensitivity. Noted for its compatibility with special alloys, such as stainless steel, aluminum, magnesium and titanium, SKD-S2 is non-halogenated, can be used with Type 1 & Type 2 penetrants. This solvent-based developer meets aerospace and nuclear industry requirements, and complies with all major NDT specifications, including ISO 3452. SKD-S2 helps speed up the inspection process by going on easily, drying quickly, promoting faster indication formation and minimizing post-inspection cleaning. It is ideal for machine shops, weld testing and field applications. SKD-S2 is listed on the QPL SAE AMS 2644 Qualified Product List and is approved by numerous Aerospace Primes including, Boeing, GE and Honeywell.
