From the idea to the product

First of all, the optimization potential for the use of liquid color is determined in an initial consultation. The focus here is on the current coloring method and the application-specific requirements. Advantages by switching to liquid paint. In addition, the paint in question ROWAMETRIC dosing system discussed. Depending on the manufacturing process and the coloring, different pumps can be used. For small batch sizes and many color changes, the peristaltic pump is the dosing device of choice. For “continuous runners” or very low dosages, the progressive cavity pump may be the best solution. And if the color is to be continuously injected into the melt under high pressure, the gear pump is used.

Are all key data and a suitable project has been identified, we begin with the reproduction of one or more colors according to the customer’s template. It does not matter whether it is a RAL, NCS or Pantone color, whether it should be opaque or transparent and contain fluorescent or effect pigments – we fulfill almost every wish! Of course, the color can also consist of monopigment concentrates if the goal is self-coloring with “monos”.
An initial profitability analysis can then be carried out based on the resulting liquid color dosage and the sales price. As liquid coloring offers many other advantages in addition to lower coloring costs, all aspects of the production process must be considered in the cost analysis.

The liquid colors and additive concentrates of the ROWASOL are an alternative to conventional masterbatches. They consist of pigments or dyes that are dispersed discontinuously at room temperature in a solvent-free, liquid carrier system. Special wetting agents and rheology additives ensure optimum distribution of the pigments and stability of the dispersion. Depending on the application, the use of liquid colors can provide advantages in terms of the amount of colorant used, the homogeneity of coloring, color change times and storage. In addition to customer-specific color settings, we also offer optimally pre-dispersed monopigment concentrates that allow the user to make their own color settings to achieve maximum flexibility.
