Bombardier Aerospace is the latest manufacturer to approve two next-generation waterborne structural primers from AkzoNobel Aerospace Coatings following an extensive series of tests and trials.
The first, Aerowave 2001, is an epoxy corrosion inhibiting primer with a VOC level of less than 250g/l. Whilst the Bombardier (BAMS565-001) specification requires the product to contain some chromate, the advanced Aerowave formulation means it can be achieved with up to 75% less than other currently approved products Overall chromate usage is reduced and lower chromate content in turn helps to cut coatings weight- by around 20% at comparable film thickness- contributing to lower operating costs.
The second, Aerowave 2002, is a non-inhibiting chrome free epoxy primer used for composites and has been approved to Bombardier specification BAMS565- 014.
