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.
In today’s advanced electronics applications, adhesives, encapsulants, sealants, and other chemistries can be the “horseshoe nails” of mission-critical electronics systems.
Once a fringe player, solventless adhesives have become a workhorse in the laminating industry. Coim’s Dave Engel discusses how this happened and why solventless is such an attractive alternative to solvent-based adhesives.
