RTV Liquid Silicone Rubber material two-part platinum-cured elastomer that can be pouring into mold
RTV (room-temperature vulcanizing) sealants
These silicone polymers work with a condensation reaction in humidity at typical room conditions,
but the cure can be accelerated by increasing temperature and humidity.
RTV sealants are easy to install, and they offer relatively low cost and good adhesion.
