Wetting and dispersing additives | Rheological additives | Defoamers and air release agents | Surface additives | Substrate wetting agents Let it flow … Consistency is critical. The more viscous a material, the more awkward it is to process. Very low viscosity materials present a challenge. Our rheological additives allow you to control the flow characteristics of your products. Ketchup is a tricky material. Sometimes there is considerable The rheological series for coatings can, for example, ensure delay before it flows out of the bottle, and other times you that they are not applied too thinly or too thickly. They are end up with more on the plate than you need. Why does applied without forming droplets or bubbles. This way, they it take so long for it to get moving, while water or oil flow ensure a uniform coating with a thickness that suits the immediately? product; and prevent the sedimentation of solids. The character of more viscous materials is dependant on the For decades we have continuously advanced our knowledge formulation. Ketchup flows differently than mayonnaise, and of rheology. We have also applied the expertise gathered in both behave differently than a gel or foam. the field of coatings and paints to other applications. Today, The flow characteristics of all materials can be influenced by we also support the plastics and construction sectors, as rheological additives – after all, their name originates from well as manufacturers of paper and adhesives, as well as the ancient Greek verb “rhei”, which means “to flow”. formulators of care products. Our rheological additives can help to improve various products. It all starts with the molecular structure Our rheological additives act at the molecular level. They generate an interaction between the molecules, specifically influencing the flow characteristics of the respective materials. This improves the properties of the respective product and considerably facilitates its processing. Without treatment, Rheological agents – a selection metal pigments will •BYK®-430 is a versatile liquid rheological additive for settle. By adding a BYK medium-polarity systems. It can be incorporated with additive, we can reduce the settling in the basic materials that come into contact with food. coating. •BYK®-R 605 is used as a thixotropy enhancing additive in unsaturated polyester resins, epoxy and polyurethane systems. •BYK®-D 420 is a liquid rheological additive for aqueous or water-reducible systems and contains DMSO as a solvent.
