This results in personnel-, time- and cost-intensive manual labour. With its 2K coating system, Sulzer Mixpac is setting a completely new professional standard in this field. Both new application systems, MixCoat™ Spray and MixCoat™ Flex, combined with the tried and true 2K cartridge technology and a newly developed spray mixer, form these revolutionary new systems. They not only simplify difficult repair jobs, but also create value-added, real cost advantages.
protection or as sealants, e.g. in ship and bridge building, for pipelines or wind turbines. Both components of a 2K coating are non-reactive by themselves. They only cure when they are brought together in the correct mix ratio. This is why they can only be mixed immediately before they are to be used. Previously, there was no appropriate technology to automate this process. Existing systems involve many challenges as they often use inferior quality cartridges, which can lead to leaks and contamination during storage. Additionally, these cartridges cannot easily be filled without incorporating air, which leads to off-ratio mixing problems during use. The existing systems are often complicated and not easy to use. For example, users complain that the dispensers are very heavy, that the air hoses are loose and jam during use, and that the air supply is awkward to handle. Manual mixing and application, however, also involve numerous disadvantages and risks. Both the mixing and the application are very time-consuming, especially when

Sighing, he dipped his brush and passed it along the topmost plank.” So it was for Mark Twain’s titular hero, Tom Sawyer, when he was made to paint a fence as a punishment for fighting. In Mark Twain’s day, painting with a brush was the only way to paint large objects. While the technology in this area has made huge progress since then, two-component (2K) coating materials are often still, to this very day, mixed by hand and applied with a brush. These functional coatings serve as corrosion
