ACRACOAT ANTI-CORROSIVE

Order here

Our Acracoat line of Anti-Corrosive coatings offers an environmentally friendly solution in protecting metal surfaces from corrosion. Acracoat works by leaving a thin clear film that is impermeable to moisture and surrounding elements. Acracoat is a water-based Acrylic coating with NO harmful VOC’s.  Acracoat can be used as a primer (use before painting) or can be used as a clear coat (for use after paint)

Some Key Benefits:

·         100% aqueous, meets zero VOC criteria (EPA method 24, ASTM D-2359)

·         Acracoat will not only work as a primer, but will also work as a clear coat

·         Air dries rapidly, in minutes, similar to solvent systems

·         Can be brush, roller, dip or spray applied, after appropriate viscosity adjustment

·         Can be applied to previously rusted surfaces

·         Provides proven, long-term bond to metals, i.e. outstanding adhesion

·         Odorless

·         Can be top-coated with aqueous or solvent-borne paints, or self-top-coated

·         Primer has good outdoor weather-ability without top-coating

·         Primer has excellent, and early water and chemical resistance

·         Environmentally friendly and non-flammable

·         Rapid resistance to severe scuffing and abrasion

·         Protection is not based upon heavy metals

·         Since it is pigment-free, settling or separation in dip tanks is negligible

Acracoat encompasses a wide variety of markets.

Though the method of application, condition of substrate and coverage rate will influence performance, it is noted that Acracoat applied in two coats exhibit excellent corrosion resistance, according to DIN50021, as follows, representing 240 hours of salt-fog exposure, without top-coating:

·         No flash rusting, even over heavily-rusted metals

·         No under-rusting at the cut-line

·         No spread at the cut-line

·         No rust spots below the paint

·         No blisters on the surface.

Acracoat may be top-coated immediately or even self-top-coated. It has an outstanding weather-ability. The only caution is that it should not be applied to metals that have a fresh coating of oil or mold release, as is common practice from some steel manufacturing plants. In these cases the metal should be pre-cleaned to remove the deposits or left outdoors to weather away these deposits before priming. In our testing the anti-corrosive properties were still attained when applied over oily surfaces but this is to be avoided wherever possible.

The current market for anti-corrosive primers is held by solvent-borne coatings, typically at low solids contents (approx. 25%), and these do not meet the strict VOC (Volatile Organic Content) guidelines arising throughout North America. These perform the task reasonably, but require that the base metal be de-rusted and pre-cleaned to a large extent, and subsequent painting with a quality topcoat is necessary to maintain the anti-corrosive abilities.

  Acracoat is an aqueous primer, which we feel meets both ecological concerns and provides high resistance to rusting and long-term corrosion resistance.

·         The use of aqueous primers has in the past led to a phenomenon called “flash rusting”, whereby the water content of the coating initiates rusting allowing soluble iron ions to bleed through the wet film and appear as circular rust spots on the finished paint film. These rust spot’s compromise the integrity of the finish, and can continue to grow as rusting progresses. It is understandable then that water-based paints have found little success on ferrous substrates. Those products on the market show limited success at best, and often contain qualifiers limiting their use to previously un-rusted substrates...”substrate must be de-rusted, cleaned, and free of scaling, and should be top-coated within a specified period” to maintain effectiveness. We have an anti-flash rust additive that eliminates this effect entirely and when used in our anti-corrosive primers; it performs so well that it offers protection even when primers are applied on fully rusted substrates.

·         The second fault of aqueous coatings of the past is the need for coalescent to provide the necessary film hardness and abrasion resistance. The use of co-solvent adds a large VOC component to the paint decreasing some of the benefits of using aqueous paints in preference to solvent-borne coatings. Our primer has no co-solvent or plasticizer and can offer a zero VOC anti-corrosive primer.

·         Possibly the most important feature of these metal primers is that they do not contain any heavy metals. This offers a tremendous ecological benefit when these paints replace the more common solvent-borne products often containing zinc chromates or other toxic metal-based additives.
