SEALING WITH SILICONE

Joint deterioration can be reduced with silicone sealants, which are one-part materials consisting of long-chain silicone polymers, curing agents, and fillers. The applied sealant cures to an elastomer upon exposure to water vapor in the air, forming a continuous silicon-oxygen-silicon network. This linkage is transparent to ultraviolet and is respoonsible for the sealants' ability to hold up under the wide variety of weather conditions faced by highway joints. A 100% silicone rubber material is virtually unaffected by sun, rain, snow, ozone, or temperature extremes.
