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 haptic subjected to varying forces. Each external influence has a effects. They can be active on the most varied of materials; different effect; sun is different than rain, heat is different than wood, steel, or plastic. They also serve as release agents friction. Our surface additives allow us to design surfaces so that in aluminum die casting enabling cast products to be easily the product does justice to the required function. released from the mold. In leather applications wax based additives influence the tactility of natural and synthetic leathers.

Depending on the structure of the surface additives are also often used for aesthetic purposes. additive, the coating can benefit from additional properties: it They intensify the gloss or provide it with a matte appearance. could be water or oil-repellant, easy to clean, or particularly This enables the combination of several effects. conductive. Our special graffiti protection ensures that surfaces Coatings, for example, must combine gloss with properties can be very easily wiped clean. like scratch resistance and UV resistance. Some coatings have nanoparticles can optimize the characteristics of surfaces in the job of making the product repel water and simultaneously a variety of ways. They could, for example, increase the UV making it free-flowing. Other coatings generate surfaces that stability and also improve the scratch resistance. If additives are pleasing to the touch but as little gloss as possible. And contain tiny carbon nanotubes (CnT), they can even make others are used to support industrial processes by acting as a coating surfaces conductive. release agent. 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.
