Today’s elastomeric joint sealants are quite remarkable. For a relatively low cost, they provide much of the protection against air or water intrusion for many types of assemblies. In these applications, a sealant must adhere tenaciously to the substrates and maintain prolonged flexibility while being bombarded by wind, rain, heat, ultraviolet (UV) light, ice, dirt, and so on.
