While this product may be stronger than older formulations, it is far from vulcanized rubber as far as tear strength is concerned. It is a useful addition to one's arsenal but is not, in my opinion, a replacement for vulcanized rubber.
Hi, Spike. You are correct. In my haste to get the word out that the
RTV and heat cured silicones have come a long way in tear strength,
I did not state it properly. I should have said “approaching the
tear strength of natural rubber.” Actually, some of our heat cured
silicones are a lot closer to natural rubber than our silicone RTV.
Thanks for pointing it out. Best wishes,
Bill Mull
