Johnson & Allen Neocol B magnetic ink is a highly sensitive isoparaffin-based black ink for non-fluorescent wet methods magnetic particles in a carrier fluid to allow mobility under the influence of magnetic fields. 
 
Neocol B uses the highest grade of magnetic particles which have been selected for their response to very low magnetic fields and for low coercivity. Making this black magnetic nk response whilst avoiding coagulation.
