Applications

SE-F Series pad printing ink is a 2-component silicone ink for printing on medical and high-tech silicone rubber parts. This inks applied via screen printing, pad printing, or spray coating. Natron SE-F medical grade silicone ink has very high opacity, gloss, flexibility, and resistance to chemicals and abrasion.

How to Mix SE-F Series silicone ink

The SE-F Series is a 2-component printing ink. A solvent and catalyst are required additives to use this ink. Let us assist by guiding you in the specifics on how to mix the SE-F series inks. Before mixing the ink with the additives, stir it thoroughly. Add the hardener, then stir thoroughly.

Other required supplies: Weigh scale, ink mixing sticks, ink mixing cups, and PPE.

NOTE: The mixing ratio for the Silicone ink (A) and the LG catalyst (B) is the same for pad printing, screen printing, and spray coating. The difference is in the amount of solvent added after the ink and catalyst mixture.

Mixing ratio: 10:1 (10 parts ink : 1 part catalyst ) – The catalyst is 10% of the inks weight.

  • Add 10 parts ink to the mixing cup. Note the weight. Add 1 part ink; e.g., if you want to mix 20 grams of ink, you add 2 grams of catalyst.
  • Mix these two component thoroughly.
  • Add solvent: For pad printing (5 – 60%) of the inks weight. For screen printing, (0 – 10%) of the inks weight, for spray coating (300 – 500%) of the inks weight.

Keep in mind that the mixture of ink, hardener, and solvent is chemically reactive and must be used within 10 – 14 hours.

Printing Parameters: Screen printing

For screen printing, use any of the commonly available polyester meshes and solvent-resistant emulsions. Use 200–230 mesh (mesh per inch)-count screens for the highest opacity and on dark substrates. Use a mesh count of 255–305 for fine details and light backgrounds.

Printing Parameters: Pad printing

  • Use any commercially available clichés that are made of ceramic, photopolymer, laser, or steel plates. For all standard prints, the recommended cliché depth is 20μm.
  • Printing pads
    Use silicone printing pads. The ink works regardless of the hardness (durometer) of the pad.
  • Printing machines
    The Natron SE-F Series is suitable for both closed-cup and open-ink-well machines. Use the appropriate thinner for the correct type of machine.

Labeling and safety information

Material Safety Data Sheets (MSDS) for the silicone ink SE-F Series and its auxiliaries are available in accordance with EU and US regulations, providing comprehensive information on all critical safety data.
