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: A waterborne coating composition comprising a waterborne epoxy coating with hydraulic cement, which is capable of a thin initial application. The coating composition may be made, stored and transported as a two-part composition, where each part is a pourable liquid. The waterborne epoxy composition cures under normal conditions and adheres to surfaces including masonry, concrete and metal.

Abstract: A method for controlling uniformity of applied film thickness of clear protective coatings by means of a color-dissipatable dye additive which dissipates within a reasonable timeframe, generally from hours to a few days, leaving the applied film with no evidence of its use during the application phase. The color additives temporarily impart color to an otherwise clear coating, and subsequently dissipate over a short period of time. An embodiment of this technology includes the addition of a compatibilizer carrier solution to increase the ease of measuring the dye for addition to the clear coating.
