The Chemistry of Waterborne Coatings

A basic understanding of the chemical nature and behavior of water-borne finishes, by the industrial user, may help remove much of the mystique surrounding them. Chemically, the water-borne paints are identical in most respects to solvent-based paints, i.e. in curing mechanism (brake or air dry properties), in polymer makeup (the basic element of the finish which is responsible for physical properties of the dry film), and in film integrity. In fact, the presence of water is purely for application and viscosity purposes, as is the thinner (VMP, Mineral Spirits, Toluol, Etc.) for solvent-borne.

How these polymers are dispersed or dissolved in water will relay significant information into the physical properties; i.e. gloss viscosity (the fluidity of a material), impact, abrasion resistance, scrub-ability, solvent resistance, corrosion resistance drying properties. Below, is our diverse line of water-borne systems available for your industry needs.

Waterborne

  • Waterborne latex single component acrylic-vinyl-rubber copolymer with dehydrated V.O.C. of 0.6 – 2.4, for use as a primer, topcoat or direct-to-metal paint. Has superior chemical resistance and abrasion resistance to any known single or multi-component urethane or epoxy. Possesses a medium gloss of 75% – 85% (60 deg. head). Gloss retention is comparable to many two-component urethanes.

  • Waterborne dispersion two-component epoxy-copolymers with dehydrate V.O.C. range of 1.4 – 2.3 for use as a primer-topcoat, or direct-to-metal paint. Possesses excellent gloss retention and good chemical corrosion resistance.

  • Waterborne solution acrylic-alkyd copolymer with a dehydrated V.O.C. range of 1.2 – 2.9 for use as a topcoat or direct-to-metal paint. Possesses excellent gloss retention and dilute acid and alkali resistance.

  • Waterborne solution alkyd, epoxy ester and vinyl copolymers for use as a primer for two-coat application. Dehydrated V.O.C. range of 1.4 – 2.9.

  • Waterborne latex single component acrylic copolymer with dehydrated V.O.C. of 0.6 – 2.4 lbs. per gallon. For use as a primer-topcoat or direct-to-metal paint. Possesses gloss of 83% – 90% (60 deg. head), with gloss retention comparable to many two-component urethanes. Forward and reverse impact of 160 – 180 psi; and abrasion resistance is excellent chemical resistance is limited o dilute acids or alkali.

  • Waterborne latex single component acrylic-vinyl-rubber copolymer with no measurable EPA V.O.C. Possesses similar properties to Thermalbond systems and may be used in areas where zero (0) emission is required.

  • Waterborne dispersions, emulsions or solution coatings. For use as a quick release coating for interiors of plastic pellet hoppers, coal cars, fly ash hoppers, refuse containers and trucks, filled with PE or Teflon extenders.

  • Waterborne dispersion single or two-component urethane-copolymers with dehydrate V.O.C. range of 1.6 – 2.4, must be used with Aqua-Epoxy primer for optimum results.
