Cold bonding for rubber gaskets joins lengths of material without the use of heat. This bonding technique doesn’t require low-temperature conditions, but is called “cold” because no heat is applied to the gasket. By contrast, hot splicing requires either a conventional heat source or infrared (IR) light. Vulcanization and molded corners for rubber gaskets also involve heating gasket materials.
With cold bonding, an adhesive is applied to the ends of the lengths that will be joined together. Different types of bonding systems are available, including compounds that vary in terms of viscosity, chemistry, and material properties. Cold bonding for rubber gaskets can save time and eliminate tooling costs, but engineers need a complete understanding of this joining method before choosing glued gaskets. (more…)
