Choosing adhesives
for composites assembly
Adhesives are the 1st class choice
!! Assembly of similar and dissimilar substrates
!! Weight reduction compared to other mechanical
assembly
!! Reduce the stress concentration
!! Superior fatigue resistance
!! Easily processable (manually / automatically)
!! No damage to the substrates (no holes)
!! Sealed joints
!! Compensation of dimensional tolerances
!! Aesthetic aspect
Requirements for composites bonding
!! Good adhesion to the substrates
!! High mechanical resistance
!! High peel resistance
!! High temperature resistance
!! High toughness
!! Good chemical / environmental resistance
!! Low temperature cure

Araldite® adhesives
Huntsman’s comprehensive range of epoxy, polyurethane, methyl methacrylate and
phenolic adhesives meets 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 keeps 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.
