2. Paint touchup may be required on an aircraft following repair to the surface substrate. In the case of a repair and touchup, once the aircraft paint coating has been identified, the surface preparation follows some basic rules. For a spot repair that requires blending of the coating, an area about three times the area of the actual repair will need to be prepared for blending of the paint. Because epoxy holds well to surfaces and doesn't dry as hard as enamel, epoxy doesn't become brittle and crack or chip from the plane. The toughness of enamel makes it strong enough to handle the conditions to which an aircraft is regularly exposed. For best results, the lacquers must be applied over fresh, successive coatings of wash primer and modified zinc chromate. The standard primer for aircraft applications is zinc-chromate. Zinc chromate is often the go-to for the former and the latter is used to give the aircraft a nice shiny look. Enamels are mineral spirit based, and acrylics are waterbased. Our goal is to be your one-stop shop for all your aircraft refinishing needs! Some detailed information for the identification of each finish is necessary to ensure the topcoat application does not react adversely with the undercoat. Because of these rigorous demands, there are generally only two types of paint used for aircraft: epoxy and enamel, one of which is less hazardous but less durable and the other which is stronger but more expensive. See more ideas about aircraft painting, aircraft, paint schemes. Uniform Surface Corrosion. Apply two light coats over the sanded repair area, slightly extending the second coat beyond the first. General safety precautions should be followed when you paint and when you use special types of paints. Typical application is by spray gun. It was very effective in removing multiple layers of paint. Do not use MEK on nitrocellulose finishes. just a silly thing - but was interested in what members thought of current paint jobs on the various models of planes in the air today. A wide variety of aircraft paint options are available to you, such as metal. PMB is similar to conventional sand blasting except that soft, angular plastic particles are used as the blasting medium. There are lots of different brands of model paints, such as Humbrol, Tamiya, Xtracolour, AeroMaster or Gunze Sangyo. Photoluminescent Paint. The paint on the Piper Archer that was tied down next to my aircraft was completely dull and faded after only 3 years. The MEK picks up the pigment from an acrylic finish, but has no effect on an epoxy coating. First, let’s take a look at some of the common types of corrosion seen in aircraft. EFS-2500 has no chlorinated components, is non-acidic, nonflammable, nonhazardous, biodegradable, and has minimal to no air pollution potential. // Leaf Group Lifestyle. Cleanup is easier, and the product complies with EPA rules on emissions. Old wash primer coats may be overcoated directly with epoxy finishes. Often the two paints are split by laying a base coat of enamel to provide the color and design for the aircraft and then applying a second coat of clear polyurethane to supply strength and extra shine. It's a fact of aviation life. Damage to epoxy finishes can best be repaired by using more epoxy, since neither of the lacquer finishes stick to the epoxy surface. These paints are sprayed over epoxy primer after being thinned to proper consistency using enamel thinners. If hanger space is available, Aircraft Paint Booth Inserts may be the perfect solution for your refinishing operations. PMB is most effective on metal surfaces, but it has been used successfully on composite surfaces after it was found to produce less visual damage than removing the paint by sanding. Surface corrosion is … Plastic media blasting (PMB) is one of the stripping methods that reduces and may eliminate a majority of environmental pollution problems that can be associated with the earlier formulations of some chemical stripping. Industrial enamel is very different from commercial enamel. Allow to dry according to the material data sheet before buffing and polishing the blended area. With Cotton Wad Saturated With Test Solvent, PS Carbon dioxide pellets (dry ice) used in conjunction with a pulsed flashlamp that rapidly heats a thin layer of paint, which is then blasted away by the ice pellets. Joined: Feb 23, 2005 Messages: 34,385 Display Name: Display name: Tom-D. Here, the paint thickness must be within exacting limits for any particular aircraft or group of aircraft types. According to United Airlines, their aircraft are repainted every seven years on average. The first rule, as with the start of any paint project, is to wash and wipe down the area with a degreaser and silicone wax remover before starting to sand or abrade the area. For commercial airliners or business jets, your processes and equipment in aircraft painting and paint removal can make all the difference in your operation – in speed, efficiency, safety and maintaining your reputation in aerospace and aircraft MRO. For a small fee, Aerospace Reports will assist you with the paperwork process to change your aircraft N#. Our unique liveries and aircraft … Acrylic and epoxy finishes show no effects. Just wipe the surface, and do not rub. Stripping is carried out using a liquid which, at 25°C, can strip an aircraft of all its paint in 24 hours. Acrylic nitrocellulose lacquers may not be used over old nitrocellulose finishes. It provides protection for the aluminum or composite structure from corrosion, bugs, rain and the sun. The most experienced painter, the best finishing equipment, and newest coatings, do not produce the desired finish on an aircraft if the surface was not properly prepared prior to refinishing. The process has minimum effect on the surface under the paint because of the plastic medium and relatively low air pressure used in the process. Figure 1. provides a solvent test to identify the coating on an aircraft. Primer is applied first, followed by the topcoat. This is done not only for the weight reduction that is gained by stripping the many gallons of topcoats and primers, but for the opportunity to inspect and repair corrosion or other defects uncovered by the removal of the paint. Paint Luster: My previous aircraft’s finish was still deep and shiny 8-years out of the paint shop when I sold it. At Jaco Aerospace, you’ll find a huge selection of aircraft paints and coatings, suitable for all sizes of planes and operations. Epoxy is a polyurethane paint formed by the reaction of a hardener and a resin. The use of several different types of paint, coupled with several proprietary coatings, makes repair of damaged and deteriorated areas particularly difficult. Similarly, epoxy has a higher resistance to chemicals, meaning it won't break down when exposed, nor does it fade or oxidize as quickly. The following procedure aids in identification of the paint finish. Aircraft paint needs to handle harsh weather conditions, bend and flex, withstand different chemicals and still look good.
