Silicone rubber is a durable, flexible, and heat-resistant material widely used in consumer, medical, and industrial products. It is the perfect material for products like toys, industrial items, and other consumer goods that need to last. But, its non-porous, slippery surface makes it notoriously difficult to print on.

Printing on silicone has always been a challenge. That’s why we developed the Natron® SE Series ink – a specialized ink solution designed specifically for silicone products. From swimming caps and wristbands to phone cases and children’s toys, to sippy cups and oven mitts, this ink delivers vibrant, long-lasting prints where others fail. With the SE Series, printing on silicone is no longer a problem.

Why choose the Natron® SE Series?

If you’re looking for the best ink to print on silicone, the Natron SE® Series offers:

  • High opacity and gloss: ensures bright, eye-catching prints
  • Extreme flexibility: as the material bends, the print bends too
  • Exceptional adhesion: bonds seamlessly to silicone rubber
  • Dishwasher safe: withstands repeated washes
  • Chemical and alkali resistant: reliable for industry use
  • Safety – approved for toy, food packaging, and industrial applications

Built for Durability:

The SE Series ink forms a permanent bond with silicone rubber meaning your designs last as long as the product itself. From toys exposed to rough play to swimming caps in constant contact with water, prints remain sharp and intact without cracking, peeling or fading. Silicone rubber is perfect for bath toys and teething toys for babies but the print designs have to be safe and reliable.

Color Options:

With this ink, there are options for printing methods: screen printing or pad printing. We offer 41 standard colors, including neon and metallic options. Need something specific? Our team can create custom color matches on request with a 24-hour turn around time. You can even mix SE colors yourself without affecting adhesion or performance.

Application & Drying:

The SE Series requires a catalyst to cure. We recommend our Natron® LG Catalyst – an advanced crosslinker for all platinum-based LSR silicone.

  • Mixing ratio for all SE Series colors: 10:1 (10 parts ink : 1 part catalyst)
  • When heat curing, either dry at:
    • 275°C (130°C) for 6 minutes, or
    • 300°F (150°C) for 4 minutes
  • Depending on the application, use a thinner to change the viscosity of the ink.
