DYKEM High Purity Ink

High-purity ink (HP) was developed for marking stainless steel surfaces where degradation, contamination, and other adverse effects are a concern. The ink is formulated with high purity. It contains very small amounts of halogens, low-melting-point metals, and chlorides, and its formulation meets the specifications of GE Nuclear Energy, GE Aircraft Engines, and the U.S. Energy Research and Development Administration (nuclear grade).
It can leave vivid and permanent markings on any surface, including metal, plastic, glass, concrete, and rubber.
Unlike tube-style markers, this pen has a sturdy aluminum body, ensuring it maintains its shape and writing feel until the very last drop.
For details on the pen mechanism, please refer to TexPen and Brightmark.
*While it can be safely used on most surfaces, please perform a surface test before use.
