Embodiment

[0086] For the examples given below, epoxy-based coatings (e.g., film layers) with multiple carriers (some with corrosion inhibitors, some without) were applied (baked at 170°C for 20 minutes) onto zinc phosphate Process steel samples for steel formation. Coatings were applied to a thickness of 25 microns using the pull down rod method. Epoxy based coatings comprise a coating matrix formed from BPA epoxy resin, isocyanate and methyl isobutyl ketone (MIBK). The carrier with the film-forming compound is formed as microcapsules. The plurality of microcapsule carrier bodies are formed from polyurethane / urea formaldehyde. The average outer diameter of the film-forming microcapsules was 5 μm. The carrier with the corrosion inhibitor is formed as particles. The plurality of particulate carrier bodies are formed from melamine formaldehyde / pentaerythritol tetraester. The average outer diameter of the corrosion-inhibiting fine particles was 1 μm. The amount of vehicle in each coatin...

Abstract

A corrosion inhibiting composition comprising a plurality of first supports and a plurality of second supports. The plurality of first supports has a first support body encapsulating a film-forming compound. The plurality of second carriers has a second carrier body encapsulating a corrosion inhibitor. The first carrier body and the second carrier body are each formed from a degradable material. Coatings and methods for inhibiting corrosion on metal substrates are also disclosed.

Description

technical field [0001] The present disclosure relates generally to corrosion inhibiting compositions and methods of making and using the compositions, particularly compositions comprising a film forming compound and a corrosion inhibitor. Background technique [0002] Many metals and metal alloys are susceptible to corrosion, which causes them to lose their structural integrity. Accordingly, methods of detecting the presence or absence of corrosion and attempting to prevent or suppress corrosion have been developed. Contents of the invention [0003] In one embodiment, the corrosion inhibiting composition comprises a plurality of first supports and a plurality of second supports. Each of the plurality of first supports includes a first support body and a film-forming compound. The first carrier body encapsulates the film-forming compound. The first carrier body is formed from a first degradable material. Each of the plurality of second carriers includes a second carrie...
