E-Coat is a Black Paint finish with a uniform thickness ranging from 15 microns up to 30 microns. Oshkosh’s electrocoating (E-Coat) immersion process provides coverage of complex parts and a uniform thickness without runs or drips. 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. } E-coat (otherwise known as Electrophoretic Coating, EP Coat, EDP Coating, Electropainting, KTL etc.) The paint is than attracted by one or the other being grounded. Hi, Varying those parameters enables the electrocoat system to build more or less film. The thickness of the coating is determined by the amount of electric current applied to the liquid. For example, will a new reinforcement structure have a negative impact on the e-coat layer thickness or neighboring parts? ClearClad Coatings offer specialty cathodic and anodic electro-coat products. We need it pass 48 salt spray test. Currently this is not possible due to the environmental restrictions on volatile organic compounds of the coatings and compliance with total organic emissions. E-coat thickness can be controlled with the following parameters mainly. This what 150 microns of paint thickness looks like. On the other hand, decreasing the solids or decreasing the temperature will decrease the film build. During the e-coat process, paint is applied to a part using a regulated amount of voltage to achieve the desired film thickness. However, the paint might be thought of as a plastic material in powder form. For a set voltage, increasing the solids or increasing the temperature will increase the film thickness. } For a given percentage solids and temperature, the set voltage will determine the final film thickness of the electrocoat. refers to the high-tech process of using an electrical current to deposit a coating onto a component. Differences Between A-Coating and E-Coating. What bath parameters can change the quantity of film deposited? Other factors such as dwell time, or immersion time and pH, may play a secondary role in film thickness as they are second-level factors. Working on the principle that opposites attract, an e-coat system applies an electrical charge to a metal part immersed in a bath of oppositely charged paint particles. This widespread preference is in part due to its exceptional corrosion resistance and consistent film thickness across a sampling of parts. ... E-coat rinsing and recovery. The higher the voltage, the higher the film deposited. At that thickness, the film insulates the part, so attraction stops and electrocoating is complete. While these metal coating technologies sound similar, the … An electrocoat system has a very wide range of application parameters that can be modified to obtain the desired film thickness. Virtually no toxic VOC's (volatile organic compounds) are emitted into the air, minimizing the impact on the environment.

A. window.addEventListener("load", function(){ John C [last name deleted for privacy by Editor] - Sterling Heights, Michigan Thickness measurements of powder can be taken before and after curing. Each of these markets has specific performance requirements. 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. These two processes are similar, as they both involve the application of a coating to a substrate for purposes such as enhancing corrosion protection, increasing wear resistance, promoting adhesion and many others. 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. Once the coating reaches the prescribed thickness, the part “insulates” and the coating process slows down. [...] 97 Film embossed to a depth of not more than 12 µm, of a specular gloss of 7 or more but not exceeding 17, measured at an angle of 60 ° using a glossmeter (as determined by the ISO 2813:2000 method), consisting of at least two layers of poly(vinyl chloride), of a total thickness not exceeding 0,5 mm, covered on the embossed side with a protective film, in rolls of a width of 1 400 mm or more but … The year 2020 will be here before you know it, signaling the beginning of a new decade and bringing changes to the world as we know it. Examples of Use: Electrocoat is found in a variety of industrial market segments. Typical electrocoat systems operate in film thickness ranges of between 18 and 28 microns. Q. The higher solvent content of the bath increased the capability of the system to build more film. It is possible to control the thickness of the coating by adjusting the electrical current to the tank. The internet is largely anonymous & unvetted; some names may be fictitious and some recommendations might be harmful. The cured thickness of the electrocoating film is usually 0.6 to 1 mil. 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. 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. E-coating is able to deliver this within the range of 12 – 13 microns. As areas of high voltage build a coating they become insulators thus allowing lower voltage areas to build up.
