Powder coating is a safe, dry finishing process used to create a protective finish. The powder coating product is made up of finely ground particles of pigment and resin which makes it low in toxicity and have low flammability. Powder coat is applied using a special electrostatic spray gun. The particles are charged with static electricity and are then sprayed on to metal surfaces that have been electrically grounded. This makes the particles adhere to the surfaces thus creating a magnetic attraction. The metal items are then heated to 350 – 450 degrees Fahrenheit. The powder coating melts and adheres to the surface creating a uniform film and then is cooled to form a very durable finish.
With the growing need to reduce pollution, powder coating is an ideal process and a safe alternative to the chromium plating processes. Since powder coating uses no solvents it is a much safer process to the environment and is virtually pollution free. The powder coating process has little impact on the environment since the process emits zero or near zero volatile organic compounds (VOC). The spray booths are easily maintained and cleaned without the use of harmful solvents or paint washes. Since there are no solvents used in the powder coating system and the coating process does not emit the kinds of vapors and fumes that liquid paint does, there is the reduced need for contamination clothing.
Powder coating started out as a finish for metal. Powder Coating can be used on any object that is made from metal including: aluminum, steel, brass, copper, bronze, titanium, magnesium, and much more! But, now powder coating is an increasingly popular finish for many of our every day products because it is solvent free.
The appliance industry powder coats such items as dryer drums, water heater jackets and oven components. The automotive industry coats springs, bumpers, wheel, louvers, frames and some of these manufactures are now using powder for primer and final body finish. Some of the every day uses for powder coating are: lighting fixtures, antennas, electrical components, filing cabinets, wagons, barbecue grills, patio furniture, metal railings, park benches and garden tools. Snowmobiles, bicycle frames, ski poles, golf clubs, exercise equipment and baby strollers are also examples of where powder coating is used.
No, the Powder Coating process eliminates the problem of run or drip marks on the finished product.
No, leave the prepping process up to Competitive Edge Coatings. If you prep your parts prior to bringing them it is likely that we will still have to prep them, so don't worry we will do all the work!
The coating colors are almost unlimited with high gloss, loss gloss, metallic and clear finishes available. Special effects are also available like: glitter, antiquing, veining, holographic, metallic and rough pebble finishes. Powder Coated finishes stay brighter and vibrant longer than other methods.
Yes, Powder Coating is much thicker than liquid paint. The extra thickness provides a more scratch resistant finish. Powder Coating is also more environmentally safe and provides a drip free and more versatile alternative to paint.
The Powder Coating process creates a hard finish that is tougher than conventional paint. Powder Coating provides a durable, rust-free, chip resistant, and long lasting finish.
Sandblasting is an effective cleaning process for hard surfaces with the use of high pressure air. The effect of sandblasting is similar to that of using sandpaper, but provides a more even finish.
Historically, the material used for sandblasting was sand that had been sieved to a uniform size. The silica dust, the "after product" produced from this process, caused silicosis after sustained inhalation of this dust. This has caused the sandblasting process to be regulated. Sandblasting is now performed in a controlled environment using ventilation, protective clothing and a breathing air supply. Sandblasting equipment typically consists of a chamber in which sand and air are mixed. The mixture travels through a hand-held nozzle to direct the particles toward the surface or work piece.
Sandblasting can be used for smoothing, shaping and cleaning hard surfaces, debarring, blending and stress relieving of any part that is hard. This process also removes slag, rust, and imperfections in steel as a preparation for various coatings. The effect of sandblasting is similar to that of using sandpaper, but provides a more even finish.
The sandblasting process can be used effectively on steel, iron, copper, brass, aluminum and glass. Sandblasting can be used toclean up fabricated parts, structural steel, castings, pipes (inside and out) pipe fittings, auto body parts and machine parts. This process can also be used on new materials to remove rust, paints, stains and glues. Sand blasting works for automotive restoration. It helps avoid a lot of hard labor, especially when working with deeply convoluted surfaces like a rusty wheel rim.
Glass bead blasting is a metal cleaning process that creates a clean, bright, uniform matte texture. The glass beads are applied to a surface using low air pressure. Using the bead blasting process a surface can be cleaned without any damage. The beads come in a variety of sizes. The smaller the glass beads, the smoother the surface, larger beads produce a more textured finish.
Bead blasting is chemically inert and environmentally friendly. This method of metal cleaning is an acceptable method when properly controlled. The glass beads used in this process are made from lead-free, soda like type glass, containing no free silica that is made into preformed ball shapes. The glass beads can be recycled approximately 30 times.
The Glass Bead Blasting process removes paint, rust and corrosion from all types of metals, from autos, trucks, equipment, machinery engine blocks, heads and intakes. Glass Bead blasting can be used on a wide range of materials including aluminum, stainless steel, copper, steel, brass, titanium, sterling silver, bronze, metal, glass, plastic and rubber. It can be used in the restoration processes of cars and trucks. Glass bead blasting is also an effective cleaning process on equipment, machinery engine blocks, heads and intakes. Bead blasting is a low cost process and can be used on decorative parts including: custom auto parts and custom motorcycle parts.
High temperature ceramic coating is often referred to as an exhaust coating, header coating or high heat coating. High temperature coatings are designed to prevent corrosion of exhaust systems and engine components. Corrosion is the breaking down of essential properties due to exposure to moisture in the air. The high temperature coating product can withstand temperatures in excess of 1200 degrees and some coatings can withstand temperatures higher that 1600 degrees. The high temperature coating process can also increase the durability and provide thermal insulation to the exhaust system. This durable ceramic coating runs between 2 and 4 mils thick and provides a hard finish which is resistant to rust and chipping. This coating process has an excellent adhesion and is abrasion resistant.
High temperature ceramic coatings are recommended for use on parts that are exposed to extremely high temperatures. Ceramic coating can be applied over chrome, aluminum, carbon steel, stainless steel or cast iron. It is ideal for parts exposed to extreme temperatures (2,000°F) such as exhaust pipes, headers, manifolds, turbo housings, intakes and brackets.
The dry film lubricant is a paint-like coating process which provides a permanent lubrication and protection from corrosion to surfaces of a part with .003-.005" coating of fine molybdenum disulfide particles. After the dry fill lubricant application and curing, the lubricants bond to the surface and form a solid film. By coating the surface of a sliding or moving part, the dry fill lubricant processes will ensure that lubrication is retained and reduce friction and result in less wear for the part or mechanism. There are dry film lubricants that contain special rust inhibitors that protect the part from corrosion in harsh environments.
Places of concern and a good use of the dry film process are piston skirts, cylinder wall, crankshafts, camshafts, bearings, gears, valve stems, rocket pivots and on any part that will be operated in a corrosive atmosphere. Another good reason to use dry film lubricant is for parts that may be stored for long periods of time.
