BYK P 2720 is a rheology additive used in combination with hydrophilic fumed silica. BYK P 2720 enhances the rheological properties of two-component systems when combined with hydrophilic fumed silica. It enables direct control of the initial viscosity of components and application viscosity of entire systems. BYK P 2720 provides spontaneous viscosity build-up after mixing and enables high anti-sagging properties, allowing application above head or on vertical surfaces without sagging. This makes BYK P 2720 suitable for advanced material applications requiring thick, stable coatings that maintain shape without dripping. BYK P 2720 combined with other additives provides tailored rheology for demanding advanced material formulations.
