Polyamide
Elektrisola offers a wide range of polyamide self bonding wire adhesive types with different properties. In comparison to other types of bond coats, polyamide types show a high bonding strength. Furthermore, some of them also have high resoftening temperatures. However, some are hygroscopic and therefore difficult to use in hot and humid climate.
