UV ADHESION PROMOTER FOR ACRYLIC AND METALS

Natron M74F UV adhesion promoter for metal printing improves UV ink adhesion on all steel and coated metal items. Also, the M74F is the best UV adhesion promoter for acrylic materials. This metal adhesion 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. Click here for the technical data sheet.

M74F Adhesion Primer guarantees excellent UV ink adhesion on metal parts—both coated and uncoated. The M74F metal adhesion primer is compatible with all OEM UV and LED inkjet inks.

Additionally, this steel primer has a surface molecular activator, which scientifically transforms the surface structure of stainless steel and coated metal surfaces to enable permanent bonding. If you want to learn more about adhesion promoters, please click here.

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 this 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 UV ink adhesion on stainless steel, you would need a steel 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.

UV printing on acrylic materials

UV printing on acrylic offers more accuracy and significantly more color options than silk screening and pad printing on acrylic. Acrylic (polymethyl methacrylate (PMMA)) is a versatile and durable material that is widely used in various applications. You will find this material in signs, displays, art pieces, and awards. To achieve vibrant, long-lasting prints on acrylic, use the M74F UV Acrylic Adhesion Promoter. The M74F is the best adhesion promoter for acrylic and it does not cause the acrylic material to cloud.

Features
Abrasion resistance

The M74F UV inkjet primer for metals aids UV inkjet ink adhesion on tough to print substrates. This primer has a strong bond to coated metal including stainless steel substrates. When applied, this primer has strong scratch resistance.

How to Use Natron® M74F UV Ink Primer

The first step is to clean the metal surface. Next, clean metal surface with alcohol and fresh paper towels until dry. While wiping the metal surface, make sure the surface has a squeaky-clean feel.

  • Wipe off / Remove dust, oil and other dirt from the substrate.
  • Wet a clean, non-woven (lint free) cloth with the M74F stainless steel primer for UV inkjet inks.
  • Wipe substrate with the wet lint-free towel.
  • Allow a couple of minutes for the solvent to completely evaporate.
  • Print the substrate or apply the adhesive onto substrate.

Frequently Asked Questions

A UV ink primer (UV ink adhesion promoter) is a coating applied to an object before printing. The application process is called pre-treatment and is usually the first step in the process. Pretreatment comes before priming and is applied as needed. Popular pretreatment methods include liquid primers, flame, Pyrosil®, and plasma treatments.
