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, 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. 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.

UV ADHESION PROMOTER FOR GLASS

Natron® G1 UV adhesion promoter for glass helps UV curable ink stick to glass, tiles, ceramics, and tritan plastic. Once cured, the G1 glass primer drastically improves the bonding and durability of UV prints made on glass.

This special UV ink adhesion promoter (glass primer for uv printing) guarantees UV and UV-LED printing ink adhesion on difficult-to-print glass substrates.

Glass Surface molecular activator/primer for UV Inkjet Printing, urethane-based coatings and adhesives is scientifically formulated to actively transform the micro-structure of glass surfaces to create permanent bonding. This glass primer for UV inkjet printing creates  permanent bonding through the use of nano-scale materials, allowing bonding on virtually every type of glass surface. Both glass and hard plastics are common substrates that are impossible to print.

Solvent based MG Series ink for screen and pad printing on glass does not require a primer to achieve permanent adhesion on glass. This is different compared to UV inks. Due to glass manufacturing process, printing on glass with UV inks is more challenging than most substrates.

Glass is an extremely difficult material to process, due to its very smooth surface, even the most durable UV inks have a problem with adhesion. In addition, the manufacturing of glass involves fritting which creates a unique glass structure. After the unique glass structure, the second most difficult problem is proper cleaning and glass preparation for printing.

Fritted Glass

Also fritted glass is a mixture of of silica and fluxes fused at high temperatures that makes glass according to finical article “scratching the surface” This property inhibits UV inkjet ink’s ability to ‘wet out’ or bond to the glass surface. This of course causes problems with many glass printing inks and adhesives. This causes weak adhesion or failure of the ink to adhere at all onto the plastic substrate. As a result, Boston Industrial Solutions, developed the Natron™ G1 Glass primer.

Characteristics of  fritted glass.

Frit is a mixture of silica and fluxes fused at high temperatures that makes glass. Because low surface energy is the primary characteristic of this group, they’re all more difficult to bond.

UV/LED Inkjet printing inks

How to Use Glass inkjet primer

The first step is to clean the glass surface with 70/30 isopropyl rubbing alcohol. Then scrub the entire glass surface tor remove all possible impurities that could be impregnated on the glass surface. Next, clean glass surface with alcohol and fresh paper towels until dry.  Make sure glass surface has a squeaky clean feel to the surface while being wiped dry.

  • – Wipe off / Remove dust, oil and other dirt from the substrate (glass).
  • – Wet a clean, non-woven (lint free) cloth with the the G1 Glass 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

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.

For traditional printing UVMK and MG Series ink for screen and pad printing are ideal to print on all metal substrates. However, due to stainless steel manufacturing process, printing is challenging compared to most substrates.

What is stainless steel?

According to Wikipedia Stainless steel is a group of iron-based alloys that contain a minimum of approximately 11% chromium. This composition prevents the iron from rusting and also provides heat-resistant properties.

Stainless steel’s resistance to rusting results from the presence of chromium in the alloy, which forms a passive film that protects the underlying material from corrosion attack, and can self-heal in the presence of oxygen. In addition, corrosion resistance can be increased further, by:

  • increasing the chromium content to levels above 11%;
  • addition of 8% or higher amounts of nickel; and
  • addition of molybdenum.

The addition of nitrogen also improves resistance to pitting corrosion and increases mechanical strength. Thus, there are numerous grades of stainless steel with varying chromium and molybdenum contents to suit the environment the alloy must endure. Learn more about stainless steel manufacturing.

What makes stainless steel impossible to print with UV ink?

Stainless steel is an extremely difficult material to print using UV inkjet inks, due to its very smooth surface. Any type of ink does not adhere on stainless steel and coated metals.  Most durable UV inks have a problem with adhesion.

In addition, the manufacturing of stainless steel and coated metal involves adding chromium which creates self healing properties to metal in the presence of oxygen. This makes printing on stainless steel virtually impossible to print.

Preparing stainless steel and coated metals for printing

Stainless steel should never be painted unless it has first been abraded with a galvanized metal-etching primer.  It prepares the surface of the metal, which allows digital UV inkjet ink to adhere onto the metal surface. No other type of primer will promote adequate adhesion. Never paint over an un-primed stainless-steel surface, or the finish will chip and peel soon after application.

As a result, Boston Industrial Solutions, developed the M87 Stainless steel UV adhesion promoter.

Characteristics of  stainless steel and coated metal.

Characteristics of stainless steel are moderate corrosion resistance, are not susceptible to stress corrosion, magnetic, cannot be hardened by heat treatment. Other uses of stainless steel include annealed condition, and have a poor weld-ability for most grades. This latter characteristic also makes its difficult for UV inkjet inks to bond
