Abstract: A composition for use in coating surfaces and a method for coating surfaces with the composition is disclosed. The composition comprises a first component including a waterborne amine curing agent, a second component including an epoxy resin, and a third component including zinc dust. The first component, the second component, and the third component being combinable to provide a zinc-rich waterborne epoxy coating, wherein the coating composition provides an anti-corrosion protection to a metal substrate.

Abstract: A simultaneous interpenetrating polymer network—geopolymer epoxy composition includes a first component comprised of a waterborne epoxy curing agent and an alkaline silicate solution, and a second component comprised of an epoxy resin and an aluminosilicate. The two components are mixed to produce a SIN-GE composition that cures at ambient temperatures. The SIN-GE composition may be a low-viscosity, sprayable composition, or may be a higher-viscosity composition. The compositions may be used as coatings, adhesives, mortars, casting materials, and the like.

Abstract: An improved anti-corrosive zinc coating composition for application on a metal substrate is provided. The coating is comprised of a siloxane polymer resin in combination with zinc dust and ceramic microspheres, the microspheres having diameters of 45 microns or less. At this reduced diameter, the microspheres act as spacers for the zinc particles without interfering with the conductivity of the coating, thereby reducing the amount of zinc necessary to achieve cathodic protection of the substrate. The coating is economical to produce, provides excellent corrosion protection, and resists mud-cracking.
