4X GOLD™
SILICONE MOLD RUBBER
4X Gold Silicone Mold Rubber is soft
with extremely high tear strength and is intended to be used for very
intricate designs. This rubber is designed for hand cutting method. If you wish
to use powder separation method, use more powder than you would with other stiffer, lower strength products. If you do
not use extra powder, you will not obtain good separation. Very high pattern
finish.
We recommend that you use stainless
steel mold plates as this product tends to adhere more strongly to aluminum
plates.

scissors, cut enough rubber to fill the mold frame to about 1/2 to 2/3full. Work in with your fingers or a
