Creep stress is a material property that describes how a material resists the stress of a constant long-term load.
Creep stress problems can be evident when something simply does not hold its shape.
Creep stress can also result in a complete failure, such as when a highly stressed glue joint at the stem of a boat fails months after the glue has fully cured when the boat is moored at the dock. In these cases, it can be said that the material has flowed or "crept" due to constant stress.
WEST SYSTEM 105 is formulated to be resistant to creep-stress and Gougeon Brothers, Inc have developed a large database of creep stress performance of WEST SYSTEM epoxy, competitive epoxies and popular urethanes.
