Home - RTV Silicone Rubber Product Portfolio | RBH Ltd RTV Silicone Rubber Room Temperature Vulcanising silicone rubber technology providing resilient, elastic sealants and mouldable elastomer performance with excellent weathering, thermal stability and adhesion to diverse substrates. CAS NUMBER: 69430-23-1 Request A Sample Names RTV Silicone Rubber|Silicone RTV|Silicone Sealant Elastomer Product Overview RTV Silicone Rubber describes a class of one-component or two-component silicone elastomer systems that cure at room temperature to form resilient, elastic rubber networks. These materials are based on polysiloxane chemistries with reactive end groups that crosslink upon exposure to moisture, catalysts or heat, producing elastomeric sealants, gaskets and moulded parts without the need for elevated processing temperatures. RTV silicone rubbers are valued for their outstanding resistance to weathering, ultraviolet light, ozone, temperature extremes and many chemicals. They provide durable sealing, gasketing and vibration-damping performance across construction, industrial and engineered assemblies. The elastomer exhibits wide service temperature ranges, flexibility over a broad thermal span and excellent adhesion to substrates including metals, glass, painted surfaces and many plastics. RBH supplies RTV silicone rubber products suitable for formulation into sealants, adhesives, encapsulants and elastomeric components where long-term performance, environmental resistance and mechanical stability are required.
