Key Benefits of ARALDITE® 2053-05 and 2053-15
High resistance to harsh environments
ARALDITE® 2053 adhesives retain their mechanical properties under high humidity, extended heat exposure, or thermal cycling—common in the transportation, energy, and marine industries.
Flexibility and thermal expansion compensation
With high elongation at break (50% for 2053-05 and 60% for 2053-15), these adhesives absorb differential expansions between dissimilar materials, reducing the risk of cracking or delamination.
Weathering and aging resistance
Even after long-term outdoor exposure, their performance remains stable, ensuring reliable, long-lasting bonds.
High service temperature
Suitable for continuous use up to 100 °C and up to 120 °C for short durations—up to 200 °C after e-coat post-curing.
Simplified surface preparation
Minimal surface pretreatment reduces production costs and speeds up assembly. We recommend Diestone DLS, a fast-evaporating, non-chlorinated solvent cleaner and degreaser that provides excellent surface prep for effective bonding.
Versatility
Capable of bonding various substrates, including metals, composites, and reinforced plastics.
