SpletPDMS is a 2 part resin. You mix the base with the curing agent, pour it into your mold, and allow it to cure and take on the designed shape. Application note for PDMS: A 10:1 base:curing agent ratio by weight is a good starting point for PDMS ( Sylgard 184) – add less curing agent for a softer circuit and more for a harder circuit. Why PDMS?
