Factor II HCR Platinum Silicone Gum High Consistency Rubber, by it's nature has the highest physical properties than our other Silicone Elastomers. HCR Silicones also have the benefit of being dimensionally stable with very low to no shrinkage. Since it is a gum rubber you can actually sculpt your piece directly into the silicone itself. HCR's also bond well to most substrates making it a great laminate, it also has a long 6 hour working time in an optimal 65°F work space. HCR silicones must be heated to reach full cure.
