About Us. E-Coat is a Black Paint finish with a uniform thickness ranging from 15 microns up to 30 microns. E-coating (e-coat) is the preferred coating for many original equipment manufacturers (OEMs) in the automotive, agricultural and appliance industries. E-coat can produce uniform finishes with excellent coverage and outstanding corrosion resistance. However, thickness can be achieved from 15 - 30 microns consistently; depends upon the component shape & customer requirements. E-coating is more environmentally friendly : Unlike many liquid coatings, there are no solvents to evaporate in the E-coat process. Increasing the immersion time will increase the film thickness only if the film thickness level has not reached the maximum as determined by the voltage, percent solids and temperature. Good quality spray paints need to apply 12 – 18 microns to be certain of maintaining a 12 micron minimum. refers to the high-tech process of using an electrical current to deposit a coating onto a component. Both the e-coating process and powder coating process provide superior protection for metal surfaces and are based on the same principle of electrodeposition. ClearClad Coatings offer specialty cathodic and anodic electro-coat products. ElectroFin® uses a PPG POWERCRON® e-coat formulation 4. specifically designed to provide excellent edge coverage of fins with a unique polymer that controls the … E-coat is a primer paint commonly used within both the automotive and Industrial industries. Among the vast array of industrial metal finishing options are two comparable processes known as electrophoretic deposition (colloquially known as electrocoating or e-coating) and powder coating. E-coat is an immersion (dipping) process very similar to plating except we are depositing organic finishes, not metal. The process works on the principal of "Opposites Attract". The higher the voltage, the higher the film deposited. Using e-coat simulation technology allows an understanding and validation of the impact of a design change. The consistency is similar to baby powder or face powder. 1. In the past, some electrocoat engineers would increase film thickness by adding solvent to the bath. The formula to determine the square feet per gallon is (% of volume solids for electrocoat x 231) / (144 square inches x coating thickness in inches) One square foot is equal to 144 square inches. Why E-coat is superior to powder coat for cast iron kettlebells. At a predetermined thickness, this film build insulates the part, attraction stops, and the process is complete. Electronic coating thickness gauges for measuring on magnetic substrate materials use the electromagnetic induction principle. How Google uses data when you visit this site. With it being electrically deposited and its excellent throw power capabilities it has the ability to reach places where complex part configuration and high rack densities are present. Once the coating reaches the prescribed thickness, the part “insulates” and the coating process slows down. Powder coating cannot deliver much less than 30 microns and will normally work within a 30 – 60 micron range. A.

Notice how the primer/e-coat layer is lifting at the edge of the chip. I manage an e-coat facility that works parts from the size of a quarter to a rear axle on an 18 wheeler. The cured thickness of the electrocoating film is usually 0.6 to 1 mil. The higher solvent content of the bath increased the capability of the system to build more film. new LazyLoad(); However, some electrocoat applications only deposit between 8 and 10 microns for clear acrylic electrocoats, and others deposit 35-40 microns for epoxy electrocoats used in tough environmental conditions. Electrocoating is a painting method which uses an electrical current to deposit paint. Each paint has an upper limit past which you generally cannot get more paint to deposit. J.M. You couldn’t replicate a paint chip like this in a million years on factory paint. Footer. The thickness of the coating is determined by the amount of electric current applied to the liquid. This allows for … This what 150 microns of paint thickness looks like. Powder coating has many similar characteristics. A three-coil probe system is used where the central coil is powered by the instrument and the other two coils, either side of the central coil, detect the resulting magnetic field. The process works on the principle of “opposites attract” and is an economical alternative to standard coating systems. ... until the coating reaches the desired thickness. While powder coating electrifies powdered paint particles, the e-coating process involves immersing the surface in a liquid paint pool that is then electrified. E-coat thickness can be controlled with the following parameters mainly. During the e-coat process, paint is applied to a part using a regulated amount of voltage to achieve the desired film thickness. Increasing the pH on a cathodic system could increase the film thickness due to a lower dissolution of the film in the permeate stages. The higher the voltage, the thicker the film build. Compared to Powder Coating, E-Coating is a thinner coating which does not significantly inhibit thermal properties. Currently this is not possible due to the environmental restrictions on volatile organic compounds of the coatings and compliance with total organic emissions. Can a hole be removed if another one is made bigger? 3. Working on the principle that opposites attract, an e-coat system applies an electrical charge to either the metal part, or the fluid in the immersion tank. The coating thickness is limited by the applied voltage. Concentration of the paint (Non Volatile content) Substrate type, thickness range, part shape, and economics determine the best method to be employed.For uncured applied powders, height measurement can be performed with powder combs and with magnetic gages employing special powder probes. Not factory! Typical electrocoat systems operate in film thickness ranges of between 18 and 28 microns. In terms of a minimum however, it all depends. Hi, A. E-coat is also a better choice over powder coat if thickness is a concern, the paint is distributed more evenly without fluctuation. Typical electrocoat systems operate in film thickness ranges of between 18 and 28 microns. However, thickness can be achieved from 15 - 30 microns consistently; depends upon the component shape & customer requirements. As areas of high voltage build a coating they become insulators thus allowing lower voltage areas to build up. If you need a product/service, please check these Directories: Jobshops Capital Equip. } A higher pH signifies lower acid concentrations and thus lower attack on the deposited film. On the other hand, decreasing the solids or decreasing the temperature will decrease the film build. For example, will a new reinforcement structure have a negative impact on the e-coat layer thickness or neighboring parts? window.cookieconsent.initialise({ E-coating is able to deliver this within the range of 12 – 13 microns.
