690.1

Oil-based Fluorescent Magnetic Ink

The 690.1 is a ready-to-use, oil-based fluorescent magnetic particle ink designed for wet method magnetic particle inspection (MPI). It provides clear, bright, fluorescent green indications under UV light, enabling the detection of medium to fine surface and slightly subsurface discontinuities in critical parts. This ink is formulated to enhance inspection quality and accuracy, making it suitable for high-strength alloys and in-service inspections.

Features

Ready-to-use formulation: Eliminates the need for mixing, ensuring consistent application.
Low maintenance: Oil-based suspension reduces cleaning and maintenance efforts.
High sensitivity: Detects medium-fine discontinuities effectively.
Excellent fluorescent contrast: Produces bright, clear indications under UV light.
Superior particle mobility: Ensures even surface coverage for better detection.
Good dispersion stability: Maintains consistent performance over time.
Corrosion protection: Safeguards parts and equipment during inspection.
Great concentration consistency: Ensures reliable and repeatable results.
Superior surface wetting: Enhances indication clarity and accuracy

Applications

After secondary processing: Ideal for components post-machining or heat treatment.
Critical applications: Suitable for safety-critical or high-stress components.
High-strength alloys: Effective for materials requiring precise inspection.
In-service inspections: Applicable for routine maintenance and in-service evaluations.
