Wetting and dispersing additives | Rheological additives | Defoamers and air release agents | Surface additives | Substrate wetting agents Strong yet beautiful. They should look beautiful, but also be durable: Surfaces must fulfill various functions. You can use our additives to achieve the most varied combination of requirements. Wind and weather, scratching, general wear and tear: Waxes incorporate protective functions (water-repelling, Depending on the product and the application, surfaces are scratchproof) with aesthetic properties (gloss, matte) and subjected to varying forces. Each external influence has a haptic effects. They can be active on the most varied of different effect; sun is different than rain, heat is different materials; wood, steel, or plastic. They also serve as release than friction. Our surface additives allow us to design surfaces agents in aluminum die casting enabling cast products to be so that the product does justice to the required function. easily released from the mold. In leather applications wax based additives influence the tactility of natural and synthetic Adjusting properties leathers. Our additives can make a surface scratchproof or UV-resistant. Surface additives based on silicones and acrylates are They can affect water repellency or abrasion resistance. Our primarily used in paints and coatings. They help to generate surface additives are also often used for aesthetic purposes. a particularly smooth and durable surface. Depending on They intensify the gloss or provide it with a matte appearance. the structure of the additive, the coating can benefit from This enables the combination of several effects. additional properties: it could be water or oil-repellant, Coatings, for example, must combine gloss with properties easy to clean, or particularly conductive. Our special graffiti like scratch resistance and UV resistance. Some coatings have protection ensures that surfaces can be very easily wiped the job of making the product repel water and simultaneously clean. making it free-flowing. Other coatings generate surfaces that nanoparticles can optimize the characteristics of surfaces in are pleasing to the touch but as little gloss as possible. And a variety of ways. They could, for example, increase the UV others are used to support industrial processes by acting as stability and also improve the scratch resistance. If additives a release agent. contain tiny carbon nanotubes (CnT), they can even make coating surfaces conductive. Three different groups Our surface additives can be divided into three groups. The first includes our extensive range of wax-based additives, the second is based on silicones and acrylates, and the third is made up of nano additives. Surface additives – a selection •AQUACER® D 272 is a wax-based performance additive that is used to process paper surfaces. •BYK®-SILCLEAN 3700does not just generate exceptionally smooth surfaces, it also makes them dirt and oil-repellant, thereby much easier to clean. •NANOBYK®-3605 is a nanoparticle dispersion for improving the scratch and abrasion resistance of radiation-curable SILCLEAn® prevents dirt from sticking to coated surfaces, making them very coating systems. easy to clean. 12 BYK.
