OVERVIEW

High-Performance NDT Inspection

The Miller SKL-SP2 Penetrant (01-5155-78) is a premium solvent-removable, visible red dye penetrant designed for critical non-destructive testing (NDT) applications. Supplied in a convenient case of twelve 16 oz aerosol cans, this product is engineered to locate surface-breaking discontinuities with exceptional sensitivity. As a Type 2, Method C penetrant, SKL-SP2 utilizes strong capillary action to migrate into tight cracks, laps, and porosity, ensuring that even microscopic defects are identified during the inspection process.

This penetrant is formulated to produce vivid, deep red indications that contrast sharply against a white developer background, minimizing the risk of missed defects. It is widely recognized for its reliability in industrial environments and meets a comprehensive list of industry specifications, including QPL-AMS-2644, ASTM E1417, ASME, and ISO 3452. This makes it an ideal choice for certified inspectors working in aerospace, nuclear, and heavy manufacturing sectors where adherence to strict quality control standards is mandatory.

The solvent-removable nature of SKL-SP2 allows for excess penetrant to be easily wiped away with a solvent cleaner/remover without washing out the penetrant trapped within the defects. This controlled removal process enhances the definition of indications and reduces the likelihood of false positives. Whether inspecting complex castings, forgings, or machined parts, this penetrant delivers consistent, high-grade performance essential for maintaining structural integrity and safety.

FAQ

Dwell time depends on the material and temperature, but generally ranges from 10 to 30 minutes to allow the penetrant to fully migrate into discontinuities.

No, SKL-SP2 is a solvent-removable penetrant. Excess penetrant should be removed by wiping with a cloth dampened with a solvent cleaner, not by washing with water.

It is suitable for use on most non-porous materials, including ferrous and non-ferrous metals (steel, aluminum, stainless), ceramics, and some plastics.

Yes, SKL-SP2 is listed on QPL-AMS-2644 as Type 2, Methods B, C, and D, and meets Boeing PS-21202 requirements.

Yes, after removing the excess penetrant, you must apply a developer (like SKD-S2) to draw the penetrant back out of the crack and create a visible red indication.

Yes, the aerosol propellant and solvent carrier are flammable. Keep away from open flames, sparks, and hot surfaces during application.

Shelf life is typically 5 years from the date of manufacture when stored properly in a cool, dry place away from direct sunlight.

Yes, it can be used for leak testing by applying penetrant to one side of a wall and developer to the other to see if the dye passes through.
