  • 4. Araldite® adhesives < Table of content Araldite® adhesives > Selection for CFRP bonding > Solution case stories > Huntsman’s comprehensive range of epoxy, polyurethane, methyl methacrylate and phenolic adhesives meet a wide variety of application requirements across industries. Whenever long open times for large area applications, fast-curing adhesives for early removal from fixtures and rapid through-put, resistance to high temperature, water and chemicals, thixotropy for gap-filling or vertical applications, toughness and impactresistance or elasticity to cope with different thermal expansions when bonding larger structures of dissimilar materials are needed, many customers have been relying on Araldite® product capabilities. Our adhesives are available in different packaging including easy-to-use cartridges and working packs for manual applications or hobbocks and drums for higher volume applications. As a pioneer in the adhesive technologies, Huntsman keep on updating the Araldite® range to meet the newest industry trends and requirements. On top we ensure close proximity and support to our customers through an extended distribution network. Advanced Materials 4
