Title:
PRECOAT ALUMINUM MATERIAL AND ALUMINUM COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2020/054697
Kind Code:
A1
Abstract:
Provided are: a precoat aluminum material which can join various resin members; and an aluminum composite material prepared by using the precoat aluminum material. The precoat aluminum material (1) has: a substrate (2) made of an aluminum material; and a primer coating film (3) formed on the substrate (2). The primer coating film (3) includes a urethane resin. In the infrared absorption spectrum of the primer coating film (3), the absorbance AC=O value at the peak top of the maximum peak among peaks present within a wavenumber range of 1180-1330 cm-1 is 0.8 to 1.5 times the absorbance Aurethane at the peak top of the maximum peak among peaks present within a wavenumber range of 1670-1770 cm-1.
