Abstract
A self-stratifying anticorrosive coating is described herein, including a zinc-rich epoxy, a curing agent chosen from the group consisting of amines, thiols, phenols, and carboxylic anhydrides, a binding agent chosen from the group consisting of aminoalkyl dialkoxysilane, dimethoxysilane, and aminoalkyl trialkoxysilane, a graphitic material, a solvent, a water scavenger, and a moisture-cured siloxane.
Claims20
A method of curing a primer, the method comprising the steps of:
- mixing an epoxy monomer with diisocyanate;
- adding dimeric oxazolidine to the mixture of epoxy monomer and diisocyanate, wherein a diamine is formed after hydrolysis;
- curing the epoxy monomer and the diisocyanate with the diamine;
- and
- chemically binding the diamine to the epoxy monomer, wherein when all of the diisocyanate has been consumed the curing of the primer occurs.

10 more elements
A method for a self-stratifying anticorrosive coating on an associated substrate comprising the steps of:
- mixing together a photopolymerizable material, a solvent, a graphitic material, and sacrificial metal particles;
- adding a material that prevents polymerization of the photopolymerizable material inside the coating before, and immediately after, application on the associated substrate;
- adding a silane mixture.
