Supramor, Ferromor and Lumor Magnetic Testing for Industry

Through our partner Chemetall, Silmid are able to offer a wide variety of chemicals suitable for NDT in general industry, energy and automotive. A full overview guide can be found here with additional details below. 

White Light Application 

Black Inks 

Supramor 4 Black is based on very fine black magnetic particles in a high-flash type 1, odourless hydrocarbon carrier.  

The black particles have been selected for their high magnetic response, low coercivity and prolonged operational life. 

White Contrast Paints 

WCP 712 contrast-aid paints are made of a suspension of white pigments in a fast-drying solvent carrier. 

They provide an excellent contrasting white background when using the Supramor range of Black Magnetic Inks. WCP 712 offers matt finish, free from reflections, and assists the viewing of defects.

Removal of the white contrast paint after testing can be undertaken by the use of S80 cleaner. 



UV/Fluorescent Light Application  

Fluorescent Inks  

The Lumor J series includes fluorescent magnetic inks, which will fluoresce brilliant yellow-green under UV(A) light.  

Lumor is ideal for the inspection of ferro-magnetic materials, structures and components. 

Lumor J is available as ready-for-use product or can be mixed with carrier fluid or water.
