DÖRKEN is your reliable partner when it comes to innovation in the field of pigment pastes and customized solutions for tinting systems. Our sector “Colorants and Components” includes pigment pastes and customized solutions for tinting systems. By “colorants” we mean our different pigment pastes for a wide range of services. With our “components” we provide the basis for biocide-free* aqueous pastes, dispersion paints, varnishes, plasters and other coatings. In addition, we offer you services in the field of microbiology, advice and transfer of know-how when you want to create a new formulation.
As a chemical company we undertake the task of developing innovative solutions which are not only high-performance solutions but also meet modern standards. As a matter of fact, we continuously focus on our solutions and set new standards which even go beyond legal requirements. This also includes the development of new pastes. We guarantee the strict compliance with quality standards and regulations and thereby ensure that our products meet the highest requirements. With our innovative and user friendly pastes we redefine chemical industry standards – for a market which does not only embrace the needs of today but as well those of tomorrow.
DÖRKEN® WATER (biocide-free*)
The first series of biocide-free* aqueous pigment pastes for water-based systems. With a wide range of applications — from dispersions to coatings — this series of pastes sets new standards and can be used to meet certification requirements under leading environmental standards (such as RAL DE UZ 12a / 102).
DÖRKEN® UNIVERSAL (biocide-free*)
The first biocide-free* series of liquid pastes on the market with a broad and universal range of applications both for water-based and solvent containing systems. The series of pastes can be used to color transparent varnishes, varnishes and dispersion paints offers the possibility of certification according to leading environmental standards such as RAL DE UZ 12a / UZ 102 and the EU Ecolabel.
The DÖRKEN range of products comprises of paste systems for aqueous or solvent containing application cycles and for decorative or industrial purposes – always at a high level of quality.
Well-founded advice is an absolute must for us at DÖRKEN regardless of whether you intend to purchase single pastes or entire tinting systems. We put our know-how at your disposal not only when you want to change your tinting system but also when you need advice regarding a change concerning the formulations.
Thanks to the innovative filler technologies DSP1 and DSP2 it is possible to produce biocide-free* water-based formulations:
Innovative, forward-looking technology forms the foundation for products in an environment of increasingly stringent regulatory requirements. This also includes the technology behind the pastes in the form of semi-finished products. The consequent compliance with hygienic standards reduces infestations to a minimum. The whole process is further optimised by the use of functional biocide-free* fillers because they create a sub-optimal environment for germs. Moreover, the stable high ph-value of approximately 11 ensures in combination with a buffer effect that the formulation’s effect remains constant. The controlled solubility of the filler guarantees a depot effect i.e. the salt load in the aqueous phase is continuously released. The targeted control of the process contributes to stabilize the formulation preventing an unwanted contamination. For our customers this signifies a strategic advantage in the field of preservative-free pastes.
With our know-how in this area we are able to create tailor-made solutions which represent a technological advantage in the field of water-based formulations. Due to these technologies and continuously enhancing them we expand our business model creating a complex range of systems and technologies.

The increasing importance of hygiene during the production process is underlined by the implementation of innovative technologies which enable a real-time control and fast reactions to improve cleanliness and security of the working spaces.
Regular tests for contaminants, impurities and germs in the production environment are an integral part of an effective hygiene management to guarantee a hygienic production and consequently a constantly high level of product quality.
The continuous monitoring of hygienic standards plays a decisive role to minimize potential health risks and guarantee the quality of manufactured products.
