ZChek-9 Black

Oil-Based Visible Magnetic Particle Suspension

ZChek-9 Black is a black dry powder formulated to be used in wet method Magnetic Particle Inspection to detect discontinuities on light colored surfaces for optimum color contrast. Generally used for Non fluorescent Magnetic Particle inspection in Fabrication, castings & Bright Bars. 9 black may be suspended
in either ZChek-801 cart oil or in water. When water as a vehicle use conditioning agents ZChek-WA9.
