Araldite® adhesives

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 impact-resistance 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.
