Natron SE Series inks

Silicone rubber material cannot be decorated with traditional solvent, acrylic, or oil based inks.  These traditional solvent inks will dry but will NOT cross-link (cure)/ bond permanently onto the product. Over time or if the product is exposed to rubbing, the ink will easily rub off the product; i.e. the ink will fail an adhesion test. In addition, the painting or ink fill will easily come off when exposed to water, chemicals or other tests you may choose to test the product. Adhesion failure is a big failure! A no no in the decorating world! An a big NO NO, if you’ve made a gift to someone.  Additionally, pealing paint looks ugly! Gifts and give ways should last forever and should leave a lasting impression.

Steps to ink filling engraved Apple Watch Bands

Below are needed supplies:

Step 1: Create your monogram or other design in Silhouette Studio and save it as an SVG – this is if you are using Glowforge laser.  Other lasers have different settings. Make sure that the settings are perfect for application. Align your Apple Watch band, pin it down and engrave it.

Step 2: Clean up the engraved part. You can use our Type SF Solvent with a brush to get this off.

Step 3: Color fill the engrave Apple Watch Band with SE series inks. Below are instructions on how to prepare the silicone ink.

1. Preparing the Ink to print

Needed tools & ingredients

Place a mixing cup on the scale and tear the weight. Pour Natron™ SE silicone ink onto a mixing container and note the weight.

Add Catalyst to the ink. The catalyst should be 10% of inks weight. E.g. if the ink weight is 100 grams, add 10 grams of the catalyst. Mix the ink and the catalyst thoroughly.

If you wish to change the viscosity of the ink, add the SF solvent up to 20% of the inks weight. Mix the SE Silicone ink, the catalyst and thinner thoroughly. Then, let the ink settle for one minute before ink filling the Apple Silicone watch bands.

2. Ink filling the engraved Apple watch bands

Color fill engraving using the mixed silicone ink. To make the job easier and reduce mess, use a syringe or one of our ink filling bottles.

4. Drying and curing curing the Apple watch band

The SE series must be cured using heat.  Let the ink filled silicone watch band sit for about 30 minutes. This helps any air bubbles get off the ink. The bake the product at 200℉ for 10 minutes or 250℉ for 6 minutes. Note, very high heat will create bubbles.

Alternatively, you can leave the ink filled part for hours or overnight and then bake the part in the morning. This yields the best results. And there you have it, a permanent ink to fill Engraved Apple Watch Bands.
