Wetting and dispersing additives | Rheological additives | Defoamers and air release agents | Surface additives | Substrate wetting agents Perfectly distributed and stabilized. Mixing means “to distribute and stabilize evenly.” It is a challenge to distribute the finest particles both in thin and viscous carrier media. This applies to pigments, metal flakes, and also to fillers. Our wetting and dispersing additives enable you to wet and stabilize these small particles. Take finely chopped herbs, oil and vinegar; mix them all From plastics to paper together, et voilà! – you have a salad dressing. But it´s not long We use our dispersing additives to evenly color the materials in before the herbs clump together and sink to the bottom of the plastics. They also help to improve the mechanical properties bowl. That´s why you have to shake the dressing prior to use. by consistently distributing the fillers in the polymers. In paper Many blends made up of solid and liquid components behave in finishing, our additives are used to create surfaces which this manner: The particles they contain clump together, which produce outstanding results when printed upon. makes further processing difficult. Our wetting and dispersing The versatility of our dispersing additives is due to a number of additives can prevent this by encasing the particles which factors. On one hand, it depends on the molecular structures thwarts clumping, allowing the particles to evenly distribute of the particles which are to be stabilized. Pigments present and stabilize in the liquid. different requirements than those of metal flakes or mineral We originally developed the wetting and dispersing additives fillers. On the other hand, our dispersing additives are tailored to be used in paints and coatings. They are used to evenly to the carrier materials, like binders or resins, in which they are distribute pigments in the binder, resulting in radiant colors being used. and high gloss. Over time, we have specifically advanced our As we develop our range of products, we use innovative knowledge on the topic of dispersing, and today we incorporate procedures in order to offer suitable solutions for new this knowledge in the most varied of applications. trends. For example, our DISPERBYK® series was developed using controlled polymerization technology (CPT). Our latest development from this series boasts virtually no volatile organic compounds which could cause odor annoyance. Dispersing additives – a selection •DISPERBYK®-2000 was developed from controlled polymerization technology (CPT). It is ideal for use with deep black automotive coatings. •BYK®-9076 is a dispersing additive that can be used in a variety of plastics and coating systems. It is particularly suitable for stabilizing carbon blacks. •DISPERBYK®-2163 is a wetting and dispersing additive for Poor dispersion without additive: Good dispersion with BYK additive: solvent-borne coatings and printing inks as well as pigment milky film clear film concentrates. •BYKJET®-9170 fulfills the special requirements placed on dispersing agents in state-of-the-art inkjet and digital printing. 6 BYK.
