M74F UV INK PRIMER FOR METAL FOR UV PRINTING
Natron M74F UV ink adhesion promoter for metal printing improves UV ink adhesion on all steel and coated metal items. This metal primer strengthens the bond between UV ink and the metal substrate, primarily stainless steel. Once cured, this stainless-steel primer drastically improves the bonding and durability of UV prints made on metal.
M74F Primer for UV Printing on Metal is formulated to guarantee UV ink adhesion on metal parts—both coated and uncoated. M74F metal primer is compatible with all OEM UV and LED inkjet inks.
Additionally, this adhesion promoter has a surface molecular activator that is scientifically formulated to transform the surface structure of stainless steel and coated metal surfaces to create permanent bonding.
What makes stainless steel impossible to print?
Stainless steel is an extremely difficult material to print on using UV inks and LED inkjet inks due to its very smooth surface. In addition, the manufacturing of stainless steel and coated metals involves adding chromium, which creates self-healing properties in metals in the presence of oxygen. As a result, this characteristic reduces the metal’s surface energy. The lower surface energy makes printing on stainless steel virtually impossible with UV-based inks. For this reason, it is important to use M87 stainless steel primer when printing on metal substrates.
Can I UV print on metal?
Yes. UV printing has been used for marking metal for some time. To achieve permanent ink adhesion, you would need a UV ink primer for metal—the M74F stainless steel primer. A UV ink primer (UV ink adhesion promoter) is a coating applied to a substrate before printing with UV-curable inks. UV ink primer is typically used on non-porous surfaces such as plastic, metal, and glass. It is used with a wide range of UV-curable inks, including solvent-based, water-based, and 100% solid inks.
