Abstract
Improved anti-corrosion systems or products are disclosed containing individual epoxy and curing agent fractions dispersed in low VOC ester-containing dispersants. Preferably, the epoxy fraction is a conventional epoxy resin, whereas the curing agent is an imidazoline. The dispersant advantageously includes a mixture of carboxylic acid esters, such as alkyl glutarate, succinate, and adipate esters.
Claims19
A liquid anti-corrosion product designed for application to metal surfaces and comprising a first component including an epoxy ingredient in a first compatible dispersant, and a second component comprising a curing agent for the epoxy in a second compatible dispersant, said first and second dispersants serving as a carrier for the epoxy and curing agent and which do not react to any significant degree with the epoxy, curing agent, and/or any epoxy/curing agent adducts, said first and second dispersants each comprising at least one ester selected from the group consisting of C8-C40 monocarboxylic acid esters, C4-C40 polycarboxylic acid esters, and mixtures thereof, said first and second dispersants each being present in the corresponding component at a level of from about 50-90% by volume, and said product being substantially free of water.
An anti-corrosion product comprising a liquid composition including an epoxy, a curing agent for the epoxy, and a dispersant for the epoxy and curing agent, said dispersant serving as a carrier for the epoxy and curing agent and does not react to any significant degree with the epoxy, curing agent, and/or any epoxy/curing agent adducts, said dispersant comprising at least one ester selected from the group consisting of C8-C40 monocarboxylic acid esters, C4-C40 polycarboxylic acid esters, and mixtures thereof, said dispersant being present in said product at a level of from about 20-50% by volume, and said product being substantially free of water.
