About us
Since 2004, we have been the specialist for high-quality liquid colors (or color pastes) and additive concentrates for efficient plastic processing in the ROWA GROUP group of companies from Pinneberg. Customer-specific solutions are developed and produced at the Karstädt site in Brandenburg. Technical customer service supports implementation at the customer's site step by step. The product portfolio is complemented by the ROWAMETRIC dosing system for quick and clean color changes and the ROWASOL COLOR CUBE reusable container.

LIQUID COLORS Perfectly dispersed colorants on a carrier designed for plastics.
Liquid colors were designed to make plastic coloring more efficient and therefore more sustainable. For our liquid colors or color pastes, we use commercially available pigments or dyes, such as those used in conventional masterbatches. Special wetting agents and rheology additives ensure optimal distribution of the pigments and stability of the dispersion. This ensures maximum color strength and prevents the pigments from settling for a long time. The actual carrier is a non-volatile, high-molecular system that is optimally distributed in the plastic melt and does not migrate from the end product due to its very good compatibility. If necessary, a bio-based carrier system can be used, e.g. for coloring bio-plastics or recyclates. Our products are manufactured in batches through highly effective mixing. It is dispersed until the pigments are optimally distributed in the carrier. Optional post-processing and filtration of the colors guarantees a particle fineness of up to 1 µm. Since there is no thermal energy input during production, the production-related CO2 footprint is extremely low. No matter whether RAL, NCS or Pantone, whether opaque or transparent, fluorescent or effect pigment - we can fulfill almost every wish! As a member of the COLOR COMPETENCE CENTER, we are well connected to the know-how and resources of the ROWA GROUP and can find the optimal solution even for difficult questions. For a color match please contact us! Of course, you can also purchase monopigment concentrates from us for self-coloring. As standard, we offer our products in the containers shown on the left, but we are also happy to fill them in customer-specific containers.
