Document Type and Number:
WIPO Patent Application WO/2020/241784
Kind Code:
A1
Abstract:
The present invention provides: a rust inhibitor that has excellent rust inhibiting and anti-corrosive properties, not only on iron members, but also on non-iron metal members, and can prevent rust and corrosion over long periods; a rust inhibitor composition that contains the rust inhibitor; a coating formation material; a coating obtained from the rust inhibitor, the rust inhibitor composition, or the coating formation material; and a metal component that comprises the coating. This rust inhibitor contains at least one compound represented by a chemical formula (1). (In the formula: R1 is a hydrogen atom or an aliphatic hydrocarbon group with a carbon number of 1—33; R2 is an aliphatic hydrocarbon group with a carbon number of 1—33; the total carbon number of R1 and R2 is 1—34; X is a simple bond or an aliphatic hydrocarbon group with a carbon number of 1—5; either A1 or A2 is -OH; and the other is -O-CH2-CH(OH)-CH2OH or -O-CH(-CH2-OH)2.)
