Download Audio File To start with, the foils are processed prior to the coating procedure and are typically sprayed with oil. This oil needs to be removed or considered before applying the coating. The surface tension of the substrate will be undermined by the presence of the oil. In [...]

Download Audio File From lithium-ion batteries to capacitors to solar panels, one common feature is they are all produced through a coating method. Energy storage devices describe a wide variety of products. From lithium-ion batteries to capacitors to solar panels, energy storage devices are as diverse as there are [...]

Download Audio File There are a variety of methods for encouraging fluids to stick to substrates in coating applications- corona, plasma or flame treating the substrate; adding a primer prior to coating; and utilizing a vacuum system at the coating head interface. The addition of surfactants is one method [...]

Download Audio File When there are two rolling surfaces moving in the same direction, the fluid needs to decide which surface to follow. But how is this decision made? Film split instabilities are caused in a variety of coatings and with a variety of coating techniques. Most commonly found [...]

Download Audio File Economies of scale occur when a coated product is manufactured wide, fast and in one pass. Substrates can be manufactured wide and multilayer coating can provided added functionality, but how do you make a coated product faster. The first hurdle is curing (typically the bottleneck of [...]

Download Audio File When coating a fluid, consideration of the rubbery behavior needs to be considered with the shear rate versus viscosity data. Coating rubber bands is not easy. So when you look at coating liquids that have molecules already formed, or the fluid has a rubbery nature, care [...]

Download Audio File Adhesives are a coating in the converting world that do not get a lot of respect. However, when you look at the market of adhesive coating, the technology requirements and process expertise can be just as demanding as some higher tech type coatings in the electronics, [...]

Download Audio File When looking for process, product, and profit improvements for your PSA tapes and labels, consider going back to the drawing board. Pressure-sensitive adhesive (PSA) coating is common for tapes and labels and useful for many market applications. This is a broad area that has many caveats, [...]

Download Audio File Coating equipment can be exposed to a variety of conditions-acidic fluids, corrosive chemicals, and abrasive slurries to name a few. So how do you identify the right material selection for the tooling that will carry the fluid to the substrate for application? While not an exact science, [...]

Download Audio File Coating with a self-metered system is a study of flow dynamics where we are fighting viscous forces. Depending on where the math is being applied, one force rises over another in combination with viscosity. Sometimes you need to be more concerned about elastic forces, sometimes gravity, [...]
