We often get questions about UV adhesion promoter for acrylic printing. UV adhesion promoters enhance the adhesion of UV-curable inks to various materials, including acrylics. Among the various adhesion promoters available, Natron® M74F stands out for its effectiveness in improving UV ink adhesion on acrylic surfaces. In this article, we focus on the application and benefits of Natron M74F on acrylic materials.

Acrylic makes an excellent canvas for printing in many industries because of its clarity, durability, and versatility. Like any printing process, achieving a strong and durable bond between the ink and the material is crucial for ensuring the longevity and quality of the prints. This same principle applies to acrylic printing. However, printing it with UV ink is challenging because it is smooth and non-porous. These characteristics impede the adhesion of UV inks. As a result, decorators must use a UV adhesion promoter to help ink adhere to acrylic and achieve excellent prints.

Understanding adhesion promoters

There are several pre-treatment options available on the market today. These include mechanical and chemical options. Mechanical pretreatment options include corona treatment, flame treatment, etc. UV adhesion promoters are an example of a chemical pre-treatment option. These specialized chemical compounds modify the surface energy of the material, making it more receptive to the ink. UV printing relies on this, as UV light instantly cures the inks. These promoters create a strong bond between the material and the ink, which prevents issues like peeling, flaking, or smudging.

Natron M74F: Enhancing UV Ink Adhesion on Acrylic

Boston Industrial Solutions, Inc. developed the M74F UV adhesion promoter specifically for improving ink adhesion on acrylic and metal materials. This digital primer contains active ingredients that boost the material’s surface energy. Additionally, this primer molecular composition helps the products chemically bond with both the substrate and the ink. The active primer layer creates a robust interface that enhances the durability of digital print.

The benefits and advantages of using the Natron M74F for acrylic printing:

  • Superior Adhesion: The M74F inkjet primer significantly enhances UV ink adhesion to acrylic surfaces. This primer dries clear once applied, but it alters the surface energy of the material, resulting in a stronger and more durable bond between the ink and the substrate. This results in durable prints that resist peeling or flaking, even under stress or extended use.
  • Natron M74F improves adhesion, which increases the printed product’s durability. Prints on acrylic treated with this adhesion promoter can withstand environmental factors such as humidity, temperature fluctuations, and exposure to UV light without degrading or losing their quality.
  • Versatility: This UV adhesion promoter is compatible with a wide range of UV-curable inks. This primer works regardless of the ink manufacturer. As a result, the M87 primer is adaptable to various printing applications. Whether used for signage, displays, industrial, awards, or decorative items, it ensures consistent and reliable results across different projects.
  • Application Ease: Using Natron M74F is simple. This enables this primer to seamlessly integrate into existing printing workflows. You can apply it manually or through automated systems, providing flexibility in various production environments. Its quick-drying properties also minimize downtime, increase throughput, and enhance overall efficiency.
  • Cost-Effectiveness: The price of this adhesion promoter is competitive. It not only improves ink adhesion but also reduces the likelihood of print failures. Additionally, this adhesion promoter minimizes waste and rework. This leads to cost savings in the long run. Its ability to enhance the durability of printed products also means fewer replacements and repairs, further contributing to cost efficiency.
  • Non-hazardous: This primer is user-friendly. Additionally, unlike the available adhesion promoters on the market today, it is not flammable, yet it evaporates quickly once applied.

How to apply a UV adhesion promoter to acrylic

Like everything Boston Industrial Solutions, Inc. makes, the M74F inkjet printing primer is easy to use. Simply wet a lint-free cloth, apply it to the acrylic material, wait for one minute, and print. It is that easy. In cases where you apply too much primer, use a dry cloth to wipe off the excess. Once you wipe it off, it will be clear.
