▎ 摘  要

NOVELTY - Anticorrosive-coated substrate comprises: first curable liquid layer applied to the substrate, where the first curable liquid layer has a thickness of at least 100 microm, where the first curable layer comprises at least one polymer or at least one monomer; quasi-one-dimensional particles or quasi-two-dimensional particles, sacrificial metal particles and a solvent; a second curable liquid layer having a thickness of at least 100 microm on top of the first curable liquid layer, where a percolation threshold of the quasi-one-dimensional particles or the quasi-two-dimensional particles is reached, and the first curable liquid layer and the second curable liquid were cured simultaneously. USE - The substrate is useful in fast coating compositions, which is used in oil or gas fields for coating of equipment e.g. oil rigs and pipes. ADVANTAGE - The substrate avoids amine blush and bloom in the primer and all intermediate layers, preferably in humid conditions e.g. off-shore environments.
