The importance of clean aluminium for surface treatments

How clean is clean ? And how do we know if we have cleaned your aluminium to the best possible level?

Surface contaminants, many that can’t even be seen, will impair the performance of any adhesive or coating applied to the metal. Bond strengths will be unacceptably low, especially in wet environments when surface corrosion can initiate. For Battery Electric Vehicles (BEV) in particular, high levels of cleanliness in the component structure are vitally important to ensuring the integrity and safety of the battery system. We use XRF equipment Dyne inks and UV-Fluorescence to measure the level of aluminium surface contaminants and to demonstrate compliance to specifications detailing RFU limits.

This short video explains just how we know that your metal is as clean as it can be before we apply any surface treatment.
