UV Adhesion Promoters for Industrial Inkjet Printing

PP PRIMER – PP ADHESION PROMOTER FOR PLASTICS

Polypropylene primer (Natron PP primer) is a special adhesion promoter for plastics formulated to guarantee printing ink adhesion on difficult-to-print low surface energy plastics such as polyolefins, polypropylene (PP), polyethylene (PE), (HDPE), (r-HDPE), polyacetal (POM), nylon (nylon 6-6, nylon 6/6, nylon 6,6, or nylon 6:6), EPT rubber, acetal, and nylon coated with thermoplastic polyurethane (TPU). This adhesion promoter for polyropylene reduces surface tension to improve printing ink bonding onto low-energy substrates. Both polypropylene and polyethylene are common plastics that are impossible to print. Learn what is polypropylene primer?

Both solvent-based inks and UV inks do not bond well to low-surface-energy plastics such as polypropylene. For example, TP pad printing ink for plastics prints on a wide range of plastic substrates. The same applies to the Natron 314 UV ink. However, there are some plastics that are more challenging for the printing ink to bond to than others. As a result, printing ink need printing an adhesion promoter for plastics to perfectly bond onto LSE Plastics. Additionally, the Natron PP Primer is an excellent UV adhesion promoter (primer) for UV printing on polyamide or nylon 6.6 materials.

These are low-surface-energy (LSE) plastics, according to the finecal article “How to Bond Low Surface Energy (LSE) Plastics.” This low surface energy property inhibits an ink’s ability to “wet out” or bond to the plastic surface. This of course causes problems for many plastic inks leading to weak adhesion or failure of the ink to adhere at all onto the plastic substrate. For this reason, you need the UV adhesion promoter for polyropylene plastic materials. Learn more about the EK series our Solvent based pad printing ink for plastics.

Characteristics of Low surface energy plastics, or LSE plastics

LSE plastic materials are generally soft and have a low melting point, so they’re easy to process, even at high volumes. Additionally, they have a low density, which helps with their light weight. Because low surface energy is the primary characteristic of this group, they’re difficult to print on and bond with. It is for this reason you require a Polypropylene adhesive primer.

Features
Abrasion resistance

PP Primer aids all types of plastic printing inks to adhere on tough to printing plastic substrates. This primer has a strong bond to polypropylene, polyethelene, and non-silicone rubber substrates such as EPDM. When applied, this primer has excellent scratch resistance.

Improves print quality

This plastic primer not only aids ink adhesion but also improves the color vibrancy of printed substrates.

How to use the Natron™ PP Primer

Using the Natron Polypropylene primer is easy. The first step is to make sure the surface is clean. To use the primer you will need PPE, these include gloves, face-mask, goggles, and a lint free towel.

  • Simply wipe the printing substrate(s) / surface(s) with this Natron UV inkjet primer-soaked-cloth lightly one or two times.
  • Air dry in seconds.
  • Pad print or screen your product.

For plastics after wiping down the product you have up to two days to print on the product.  As time goes the plastic regains it LSE characteristics.

Frequently Asked Questions

Polypropylene adhesive primer is designed for use on low-surface-energy, difficult-to-bond plastics such as polypropylene and polyethylene. This primer increases the surface energy of the substrate to help printing ink or adhesives better bond to these hard-to-print plastics, rubbers, and nylons coated with thermoplastic polyurethane (TPU).
