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 utilises non-halogenated solvents and can be used with Type 1 & Type 2 penetrants.
This solvent-based developer complies with all major NDT specifications, including EN ISO 3452.
SKD-S2 helps speed up the inspection process by going on easily, drying quickly, promoting faster indication formation and minimising post-inspection cleaning. It is ideal for machine shops, weld testing and field applications.
