Parker Research Dry-Visible Magnetic Particles

Quality magnetic particle powders.


Sir-Chem® dry method magnetic particle inspection powders are highly refined visible pure iron particles used for magnetic particle testing. They offer the largest range of color options to help provide the best possible contrast during the magnetic particle testing process. Sir-Chem® dry method mag particles come in grey, red, yellow, and black. These dry method mag particles are designed to be used in visible light to reveal medium to coarse discontinuities on fabricated components or weldments located on bridges, pipes, large tanks, machinery, and equipment. All powders are consistently sized in accordance with NDT industry standards and specifications.

Sir-Chem® dry method magnetic particle inspection powders provide excellent colored contrast on surfaces with good particle buildup. These dry method powders are acceptable for use on high temperature surfaces up to 800°F (427°C) except for Red being 600°F (315°C).

Although not recommended (depending on the magnetic characteristics of the inspected component) indications may form after the magnetization source has been removed. Apply Sir-Chem® dry method powders to the inspection surface utilizing a magnetic particle dry powder spray bulb or powder blower. As the current is being applied, dust the magnetic powder over the part. While magnetization is being applied gently blow off any extra powder revealing a clear and reliable dry method magnetic particle test.
