Comparison Note

Huntsman Araldite 2012 stands out as a fast-curing, general-purpose epoxy adhesive, delivering high strength and toughness across a wide range of materials. While other Araldite products, such as Araldite 2011, offer a longer pot life and lower viscosity for specific uses like electronic encapsulation, and Araldite 2014-1 provides enhanced temperature and chemical resistance, Araldite 2012 is distinguished by its rapid setting time and broad versatility. It serves as the approved direct replacement for the discontinued Araldite 2010-1. Its self-leveling properties and ability to create strong bonds on diverse substrates make it an ideal choice for both industrial and prosumer applications where quick, reliable, and durable adhesion is paramount.
