Intro
SKD-S2 is a fast-drying, solvent-based, bright-white developer used in dye penetrant testing to reveal surface flaws with high contrast. It pulls penetrant out of cracks and pores, forming a visible white background that makes flaws easier to see. This ensures reliable inspections in aerospace, automotive, oil & gas, and general industry.

When to Use SKD-S2
SKD-S2 is ideal when you need fast, reliable flaw detection with excellent contrast:
- Welds — stainless steel, carbon steel, aluminum
- Castings — aluminum, magnesium, titanium
- Machined parts — high-precision aerospace and automotive components
- Field inspections — fast-drying film for on-site work
How to Apply SKD-S2
Follow these steps for consistent, reliable results:
- Clean and dry the surface thoroughly.
- Apply penetrant and allow correct dwell time.
- Remove excess penetrant according to the process standard.
- Shake the can well. Spray SKD-S2 from 8–12 inches (20–30 cm) in light, even passes.
- Allow developer to dry. A thin, uniform white coating should form.
- Examine the surface under proper lighting — flaws appear as bright or colored bleed-out.
- After inspection, clean part as required.
Tip: Apply in thin coats — too much developer can mask fine flaws.
Coverage & Cost Efficiency
One 12 oz aerosol can typically covers 50–75 ft² with a thin, uniform film.
- Example: 3 medium weldments (15–20 ft² each) per can.
- Larger packages (5 gal, 55 gal) are best for high-volume shop use.
SKD-S2 vs. Other Developers
| Developer Type | Pros | Cons | Best For |
|---|---|---|---|
| Solvent-based (SKD-S2) | Fast-drying, excellent contrast, easy field use | Flammable, requires ventilation | Field work, aerospace inspections |
| Dry powder | No solvent hazards, stable | Lower sensitivity on smooth parts | High-temp parts, rough surfaces |
| Water-based | Safer handling, non-flammable | Slower drying, less portable | Controlled shop environments |
Troubleshooting & Pro Tips
- Too much background color? → Apply lighter coats, increase spray distance.
- No indications forming? → Check penetrant dwell/removal step, allow proper drying.
- Film fogging or dripping? → Spray in thin passes, avoid over-application.
- Cleanup: Remove developer with approved cleaner (e.g., SKC-S).
Safety, Storage & Disposal
- Flammable — keep away from sparks and flames.
- Ventilation — always work in well-ventilated areas.
- PPE — gloves and safety glasses recommended.
- Storage — keep in a cool, dry place. Do not expose aerosols to heat.
- Disposal — follow local hazardous waste regulations.

FAQs
Q: What is SKD-S2 used for?
A: It is used in dye penetrant testing to draw penetrant out of flaws and make them visible.
Q: Is it compatible with aluminum and stainless steel?
A: Yes — SKD-S2 works on most metals including aluminum, stainless, titanium, and magnesium.
Q: Does it meet AMS 2644?
A: Yes — SKD-S2 is listed on the AMS 2644 Qualified Products List (QPL).
Q: Can I use SKD-S2 outdoors?
A: Yes, but ensure good ventilation and avoid windy conditions.
Q: Aerosol vs bulk — which should I choose?
A: Aerosol is best for field use and small jobs. Bulk containers are cost-effective for shop use.
