room temperature vulcanizing
RTV stands for room temperature vulcanizing. RTV silicone begins to cure immediately upon being exposed to air, as opposed to the curing agents in water-based sealants (for example, latex). It lends itself well to working as a sealer because it is water-repellent, adhesive and holds its shape.
Does silicone prevent water?
