Abstract:
1. A method of embossing a cured silicone resin thermoset substrate to imprint patterns onto the substrate from a master mold comprising: (i) stacking a master mold with a cured silicone resin thermoset substrate such that a surface of the master mold containing a feature is facing the silicone resin substrate; (ii) applying a pressure to a product of (i) in a press at a temperature slightly higher than the Tg of the silicone resin but lower than a softening point of the master mold; (iii) cooling the product of (ii) and maintaining the pressure on the mold; and (iv) releasing the substrate whereby a feature is imprinted on the silicone resin substrate.
