Features of SI-HD Series Silicone Pad Printing Ink

Inkcups’ SI-HD pad printing ink is made up of mostly silicone because the only thing that adheres to silicone is silicone. Silicone ink is the only type of print that can bend, stretch, and move with silicone without damaging the print. These inks can alsowithstand high temperatures – silicone products are known to f be used for high-heat tasks for exactly this reason. Once fully cured, silicone ink will hold up to anything that silicone itself can.

SI-HD Series silicone ink can be either pad printed or screen printed. While we recommend pad printing, due to the ease, screen printing can certainly be an option. Pad printing lays down less ink to achieve the same look, therefore drives ink costs down and curing time is also shortened.
