Silicone RTV Sealant — Room Temperature Vulcanizing Silicone Rubber
RTV silicones cure at room temperature through various mechanisms (e.g., condensation, addition) to form flexible elastomers. They exhibit excellent temperature resistance, UV stability, and good adhesion to many substrates, making them ideal for sealing and gasketing.
