What Flaw Finder Do I Need?

What it is:
This test detects surface flaws (e.g., cracks, laps) on non-porous materials by applying a liquid dye that seeps into defects. After removing excess dye, a developer brings out the flaws for visibility.

Products to Use:

• Sherwin DR-60 Cleaner/Remover: Cleans surfaces before and after the test, removing excess penetrant.

• Sherwin DP-50 Dye Penetrant: A visible penetrant for detecting surface flaws on metals, ceramics, glass, and some plastics.

• Sherwin D-100 Developer: Helps bring out trapped penetrant from surface flaws for clearer visibility.

What it is:
Used to find surface and near-surface defects in ferromagnetic materials. A magnetic field is applied, and particles gather at flaw sites, making them visible.

Products to Use:

• Sherwin BO-1 Magnetic Particle: Black particles for detecting surface flaws in ferromagnetic materials.

• Sherwin CP-2 Contrast Paint: White paint that enhances particle visibility by providing a high-contrast background.

What it is:
Similar to magnetic particle testing but uses fluorescent particles that glow under UV light, allowing for higher sensitivity and detection of finer flaws.

Products to Use:

• Sherwin GLO-NETIC Fluorescent Magnetic Particle: Fluorescent particles for detecting fine discontinuities in ferromagnetic materials under UV light.

What it is:
This method is used to detect flaws at elevated temperatures (up to 176.7°C). The heat causes flaws to expand, trapping more penetrant for stronger indications.

Products to Use:

• Sherwin KO-17 Hi-Temp Penetrant: A visible penetrant designed for high-temperature applications.

• Sherwin D-350 Hi-Temp Developer: Enhances flaw visibility at high temperatures.

• Sherwin KO-19 Hi-Temp Remover: Removes excess penetrant from heated surfaces after testing.
