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.

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.
