Instructions For Use
Pretreatment
It is essential that all substrates for bonding are free of contamination and in as ideal a state as possible. As pretreatment varies significantly depending on the substrates being used, please refer to the Hexcel publication Redux® Bonding Technology for optimum procedures.
If there is to be a delay between the pretreatment and bonding of aluminium, the pretreated surface should be protected with Redux® 119 surface pretreatment protection solution to conserve the optimum bonding surface.
