1. A two-component epoxy-based liquid formulation comprising:
a liquid epoxy resin composition comprising,
a reactive diluent modified liquid epoxy resin present in the liquid epoxy resin composition in an amount from 80 wt. % or more comprising a C12-C14 aliphatic chain glycidyl ether reactive diluent modified bisphenol-A/F based liquid epoxy resin formed by mixing together: oxirane, 2,2′-[(1-methylethylidene)bis(4,1-phenyleneoxymethylene)]bis-homopolymer present in an amount from 61-71 wt. %; a formaldehyde, polymer with (chloromethyl)oxirane and phenol present in an amount from 14-24 wt. %; and alkyl (C12-14) glycidyl ether present in an amount from 9-19 wt. %, whereby weight percentages are based on a total weight of the reactive diluent modified liquid epoxy resin,
an epoxy functional reactive diluent present in the liquid epoxy resin composition in an amount from 5-15 wt. % to reduce viscosity and surface tension,
an adhesion promoter present in the liquid epoxy resin composition in an amount from 0.4-3.0 wt. %,
a defoamer present in the liquid epoxy resin composition in an amount from 0.2-1.0 wt. %,
a wetting and dispersing additive comprising a silicone acrylate copolymer present in the liquid epoxy resin composition in an amount from 0.1-1.0 wt. %,
whereby all weight percentages are based on a total weight of the liquid epoxy resin composition; and
a liquid epoxy curing agent composition comprising,
a liquid epoxy curing agent present in the liquid epoxy curing agent composition in an amount from 80 wt. % or more,
an adhesion promoter present in the liquid epoxy curing agent composition in an amount from 0.5-3.0 wt. %,
whereby all weight percentages are based on a total weight of the liquid epoxy curing agent composition;
wherein the liquid epoxy resin composition and the liquid epoxy curing agent composition are mixed together to provide a dual functioning single coating epoxy-based formulation that, when applied to a substrate as the single coating and cured, simultaneously acts as both a moisture vapor barrier and a primer.
