The transformation from cathode ray tubes to LCD displays has been rapid since the early 2000s. We now have thinner, lighter and bigger screens available with affordable prices. You have probably also seen pictures of flexible displays and read stories about flexible mobile phones and foldable screens. I'm sure many of you have also thought if we really need those and would it in the end be practical to have a foldable display in your pocket. Probably not, but flexible displays allow new product opportunities for many industries such as car industry and consumer products. However, one of the biggest drivers for the flexible displays is actually related to the manufacturing of the displays.
The open time, wet edge or lapping of a coating is a measure of how much time an air dry coating takes to reach a stage where it can no longer be applied by brush or roller to the same "wet" coating without leaving an indication on drying that the "wet" and newly applied coating did not quite flow together. Therefore, the advantage of having good open time in a stain would result in better general appearance of the stain.
The ability of nanocellulose and microfibrillated cellulose to provide strength in different products has been discussed and studied for a long time. MFC fibers are strong and lightweight and has large surface area which makes it an excellent candidate for strengthening aid. Some are referring to the composites containing MFC as being “the next world-changing supermaterial” (Gizmodo, 2014), while others believe that they can be part of car production (Financial Post 2017). So how is this actually working?
