EkoCrylic (includes catalyst) is a waterborne, catalyzed, acrylic urethane topcoat that is formulated specifically for metal and composite aircraft with extreme durability and gloss that does not fade with age. Similar to other catalyzed urethane topcoats on the market, EkoCrylic produces a very high gloss finish that is very durable and resistant to solvents including fuel and even MEK. However, EkoCrylic is not hazardous, flammable, or harmful to the environment which greatly reduces the health hazards and safety equipment requirements for spray applications. As with all Stewart Systems products, cleaning out the paint gun and mixing containers is done in the sink with water and EkoClean – no solvents.
EkoCrylic is available in over 50 standard colors, and a custom color match service is also available. Clear base is available for use as a clear coat, although it is not necessary to achieve a rich gloss. A flattener may also be purchased separately that will produce a semi-gloss, satin or flat finish depending on the ratio that is used.
EkoCrylic is sold as a kit including catalyst and is thinned with distilled water, so there are no reducers or cleaning solvents necessary which keeps the overall cost down. For example, if you order a gallon, you will get three quarts of color and one quart of catalyst making one complete gallon. Although the cost of EkoCrylic is typically similar to competitive products, the coverage is generally significantly greater reducing the overall weight and price of the topcoat. Typically, 2-4 gallons will cover most any light, single-engine aircraft.
Although EkoCrylic was primarily designed as a finish for the complete Stewart System, it is also an excellent option for a repaint over other finishes. Because it employs a mechanical bond rather than a chemical bond, EkoCrylic will adhere to virtually anything that has sufficient surface texture. By simply cleaning and scuff-sanding any paint finish, you can apply EkoCrylic right over it. If cleanliness is in doubt or a previous color scheme needs to be hidden, a light coat of EkoPrime or EkoPoxy may also be used as a base.
