Polyacid macromolecule primers
Patent
·
OSTI ID:7167869
Hydrophilic polyacids are described, such as macromolecules of polyitaconic acid and polyacrylic acid, where such macromolecules have molecular weights >50,000 as primers between a polymeric top coating, such as polyurethane, and an oxidized aluminum or aluminum alloy. A near monolayer of primer is used in polymeric adhesive/oxidized aluminum adhered joint systems in 0.05% primer concentration to give superior results in standard peel tests. 2 figs.
