RHEOBYK-431

RHEOBYK-431 is a liquid rheology additive for solvent-borne coatings, adhesives, and sealants to improve anti-sagging and anti-settling properties. With the aid of the pigments and fillers, the additive generates a three-dimensional network structure. The entanglement of the high molecular weight polymers is responsible for the development of the pseudoplastic flow behavior.

The polarity of the system and the incorporation temperature influence the rheological effectiveness. The settling of the pigments and fillers is prevented and outstanding anti-sagging properties are produced due to the rapid rebound in viscosity after shearing. The additive has no "false body effect", no negative influence on the intercoat adhesion, and it is easy to process on account of its liquid form.

Company

BYK has an established history of innovation such as being the first additive manufacturer to begin using Controlled Polymerization Technology (CPT), launching the first rheology-modified wax emulsion, and being one of the first companies to use nanotechnology for improving Coatings properties. BYK invests approximately 7.5% of its earnings in R&D—three times more than the industry average.
