Download Audio File When it comes to slot die fluid coating, the mathematical equations that dictate flow are fundamental, but the details are complicated. The goal with understanding the math should be not to make things more complicated, but to simplify the understanding and lead engineers and operators towards [...]

Download Audio File With the modern coating era upon us, the need to coat functional materials has grown exponentially. Whether you are looking to coat flexible electronics, solar panels, optical films, or energy storage devices, the need for fluids that provide transmission of energy is important. So how can [...]

Download Audio File Slot die coating technology is a function of the coating process, auxiliary system and fundamental technique. The decision to utilize a coating technology needs to be analyzed against these functions to determine best fit. In the era of clean, thin and precise converting operations, a customized [...]

Download Audio File Fluid coating is a world of science and art. Some things we know well, and some things have yet to be proven, and many things have yet to be investigated. So where do we start? Fluid coating is the process of depositing one or more liquids [...]

Download Audio File When describing fluid flow onto substrates to people not living in the world of converting operations is like trying to explain rocket science to a pig. Very few people ever wonder how the glue on tape is placed, or how plastic sheets focus light on a TV [...]

Download Audio File One of the best ways to not have defects in fluid coating isn't a trick with a pump or a tip with a coating head. Reducing defects works best by practicing preventative medicine. Defect prevention comes from a handful of considerations at the beginning of a [...]

Download Audio File Streak defects are one of the most common coating defects in roll-to-roll coating. They are also very elusive! How streaks are formed and progress is a combination of the development of a particle and the presence of an area where the particle can hang-up in the [...]

Download Audio File Agglomeration is a dispersion issue that can cause headaches for coating operators. Fundamentally, an agglomerate is a collection of particles that stick together and create a larger particle that can get stuck in narrow gaps or cause coating defects. Why is this such an issue? Ideally, people [...]

Download Audio File In premetered coating, a slot die is the control valve that turns fluid flow through a pipe into a precise, flat, and even coating on a continuous substrate. How does a chunk of metal do this? I like to think of a slot die as a [...]

Download Audio File Fluid coating is only as good as the quality team says it is. Once the fluid hits the substrate many things can happen - the substrate can wrinkle, air can be trapped, and curing can do more damage than good. The key is to understand where [...]
