What are the UV Curable Inks Used for Metals?

As a Uv Ink Supplier, share with you.

There are two types of UV curable inks for metal printing: cationic or free radical (acrylate). Cationic UV curable inks all contain a chemical composition based on epoxy resin. The curing speed of this ink system is slower than that of the traditional free radical system, which is generally based on acrylic resin. If properly treated, both ink systems can bring good outdoor durability to printed matter. Both cationic and free radical UV curable inks are chemically reactive. During the curing process, a hard ink film can be produced. These ink films are not only resistant to abrasion and corrosion by chemical agents, but also similar to thermosetting solvent inks.

No matter which type of ink you choose for metal printing, this ink should meet the specific performance requirements of the job. For example, the ink film formed by screen printing ink must not only have a certain degree of hardness to resist wear, scratches, ink accumulation and solvent erosion, but also have enough flexibility to facilitate people's bending, die-cutting and Press bumps.

There will not be one ink and one metal substrate that can meet all your production requirements. On the contrary, you need to deal with different coating materials and at the same time match the ink system with different coating materials and the end use of the product. If the product is used internally, it is very suitable for epoxy resin inks, and resin thermosetting inks are also available. If the product does not need to be solvent-resistant, then air-dried solvent-based inks are sufficient. If the printed matter needs both corrosion resistance and outdoor durability, air-drying and epoxy-based solvent-based inks are not ideal choices, but other traditional thermosetting or UV-curing inks can be used in this field. Your first task is to ensure that the ink film can adhere to the substrate after drying or curing, and you should choose different inks according to different materials.

What do you Know About Eco-Solvent Ink?

Eco-solvent ink, or environmentally friendly solvent ink, is a new type of outdoor solvent inkjet with high safety, low volatility, low toxicity and high flash point that has been popular in the outdoor solvent-based digital inkjet market in recent years. Ink, its development has not stalled. At present, some people have put forward higher requirements and developed it into a green solvent outdoor inkjet. It is required to have a boiling point higher than 150°C and a closed cup flash point higher than 65°C. As a   Uv Ink Manufacturer , I would like to share with you. ESL Eco Solvent Ink Advantage Compared with solvent-based inks, the biggest advantage of eco-solvent inks is environmental friendliness, which is mainly reflected in the reduction of volatile matter VOC and the elimination of many toxic organic solvents, which are no longer needed in the production workshop of eco-solvent inkjet printers. Ventilation device. Eco-solvent ink not only maintains the advantages of high-pre...

How do you know which ink to use for your printer?

If you are using a new printer for the first time, you may not be familiar with the type of cartridges your printer uses. Each printer uses a specific printer cartridge family for printing. The printer cartridge family is identified by the printer brand name and cartridge number. 1. The easiest way to determine which cartridges are appropriate for your printer is to turn on the printer and see which cartridges are currently in the machine. 2. If there are no cartridges inside the printer, you can search for the printer model on the manufacturer's website. The manufacturer's page for your printer should contain a list of compatible cartridges. 3. You can also refer to the printer user guide that came with your machine to identify the cartridge series.    Recognizing individual Cartridges for Epson As you know, each type use individual cartridges for Epson printers , which means that each cartridge contains a specific color of ink. This is different from HP's thre...

Solvent Dye Sublimation Ink

Solvent dye sublimation inks are basically pigments suspended in an oil base, but of course there are other stabilizers and surfactants in the mix. Solvent inks may contain a chloride-vinyl acetate copolymer at 2-6%, a polymeric amide at 0-4%, a ethyl acetate at 0-4%, 2-methoxy-1-mthylethyl at 0-1.25%, N-butyl acetate at 0-2.5%, and Butan-2-OL at 0-0.5%. There will also be a distillate at 0-3%, and at least one subliminal disperse dye at a rate of 0.25% to 9%, which must be insoluble in either an included ether or acetate. Propylene glycol must be included in the range of 0% to 2%, and an additional acetate will make up 78% to 95% of the solution. This entire solvent based dye sublimation ink solution must, when mixed properly, be able to flow through the head of an ink jet printer in order to function properly.   Aqueous Dye Sublimation Ink In aqueous dye sublimation ink, water is the solvent in which the pigments and other ingredients are suspended, and the water will typically m...
