Heat Cure HCR (High Consistency Rubber) 29 Shore A Durometer (HCRA 4130)
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.

silicone elastomers. Each elastomer is supplied as a two-part kit (Part A &
Part B), equal portions of which must be thoroughly blended together prior to
